The oasis data has been rerun with these corrections: 1. sonic data (except for NUW sonics) tilt corrected, and rotated to geographic coordinates. 2. CSI soil moisture (Msoil.5cm.1,2,3) corrected by a quadratic fit to the manual measurements (from Tony and SteveS) 3. Fix to Tcase.CNR1a as requested by Scott and Jerry. Recalc of Rlw.in|out.CNR1a using Rpile and corrected Tcase. 4. NCAR prop data from Jun 17-Jun 21 21:15Z flagged as NA. (The azimuths were entered into the props on Jun 21). The OKMN data starts on Jun 24. 5. Units of rain corrected from "183mm/hr" to "mm/hr" in netcdf file.
This will be the final daily log. the project is over today. Intercomparisons for the radiation sensors and the hygrothermometers are underway and will continue until Sunday a.m. cocklebur will be taken down shortly. Weather: Mother nature has blessed us with rain accompanied by lightening. Teardown will have to wait until the weather passes.
As of 430cdt the tower with hygrothermometers was lowered and comparison test was started. The tower is level to the ground with the sensors pointed to the south. The new blower remains connected to all the sensors except the middle one (6.5) The Radiation comparison began about 4:30cdt. Sensors are placed on a piece of plywood laying on top of the schwartz box. LEvel enough for govt. work. Fans are connected.
Aug 7 Friday Last full day of ops!!! Wx: Very much the same as yesterday. AM clear, hazy in east. High expected mid 90`s Base: OK. T/RH: OK. Dropped tower at 4:30cdt for 24 hr comparison. P: OK. Wind: OK. Radiation: Normal. 4:00 cdt began start of 24 hr comparison test. (T,G,M)soil Gsfc: Good agreement. Msoils: ok. Tsoil: ok. Same, NCAR#1 still high during daytime. NCAR#3 still lower at night Sonics: normal. NUW1 down NUW2 down. Removed sensors and tower today. Krypton: OK. fastT: Same. bph: OK. Rain: Are You Kidding? Comments:
Aug 6 Thursday Wx: AM clear, hazy in east. High expected upper 90's. :-( Not what the PI needs.. By afternoon some alto-Q clouds developed, perhaps 40% coverage. Base: OK. Reprocessing of covars to add OKMN variables resulted in problems with the legend labeling but the data are presented. T/RH: OK. 0.5m,1.5m,4.5m,9m on MegaTurbo aspiration. RH: the OKMN 1.5m/9m agree with each other and are suspiciously close to each other but not as consistent with the NCAR sensors at the same level. The OKMN 'sniffer' used in the bowen ratio has clearly much slower response. NCAR 6.5m is reading less than accurately due to fan. P: OK. Wind: OK. speed profile looks good. Radiation: Normal. Will need to look more closely at sensors with clouds for smaller changes like response time. Rnet is consistent except for occassional excursions by the OU NRLite. This occurred this morning with the rain, but also for ~2 hours yesterday afternoon in cloud cover around ~11:00 CDT Rlw offset on CNR1a in/out ~+25w/m^2 (T,G,M)soil Gsfc: Good agreement. Msoils: ok. Tsoil: ok. Same, NCAR#1 still high during daytime. NCAR#3 still lower at night Sonics: normal. NUW1 began losing asamples again last night and data looks bad once again. We will take it down today also since #2 is out of action. Data not good enough for the type of intercomparisons needed anyway. NUW2 down. Krypton: OK. fastT: Same. NCAR fast-t is erroneously high. bph: OK. Rain: 1.8 mm (7-tips) at about 6:00 CDT 5 Aug. Comments: Some trouble plotting using "geo" coords. Instrument coords. work ok. This was an effect of having an extra sonic (csat) without having an orientation field entry in sonics/azimuth.dat
Aug 5 Wednesday Wx: Overcast, Some rain overnight ~1.8mm recorded. High expected upper 80's. Base: OK. Reprocessing of covars to add OKMN variables resulted in problems with the legend labeling but the data are presented. See log message about base and UW#2 bringing down DAQ briefly around 20:00 - 20:30Z. T/RH: OK. 0.5m,1.5m,4.5m,9m on MegaTurbo aspiration. RH: the OKMN 1.5m/9m agree with each other and are suspiciously close to each other but not as consistent with the NCAR sensors at the same level. The OKMN 'sniffer' used in the bowen ratio has clearly much slower response. NCAR 6.5m is reading less than accurately due to fan. P: OK. Wind: OK. speed profile looks good. Radiation: Normal.

Tsoil: ok. Same, NCAR#1 still high during daytime. NCAR#3 still lower at night Sonics: normal. NUW1&2 Sample loss problem removed after zeroing process. NUW1 is beginning to act up again but not nearly as bad as before. Data is probably not good enough for the type of intercomparison needed. NUW#2 data kaput ~11:00, sensor died totally later. Krypton: OK. Has some trouble with the rain as expected but comes back. fastT: Same. NCAR fast-t is erroneously high. bph: OK. Rain: 1.8 mm (7-tips) at about 6:00 CDT 5 Aug. Comments: Some trouble plotting using "geo" coords. Instrument coords. work ok. Soil sample taken Wednesday 5 August, ~11:30 CDT after having a little rain last night. This is probably the last opportunity for a sample.
Aug 4 Tuesday Wx: Cloudy, 30% rain in the forcast. Some drops coming out of the clouds. High expected around 90-F. Base: OK. Reprocessing of covars to add OKMN variables resulted in inability to look at covars using rh values. Hopefully this will disappear soon. T/RH: OK. 0.5m,1.5m,4.5m,9m on MegaTurbo aspiration. RH: the OKMN 1.5m/9m agree with each other. NCAR 6.5m is reading less than accurately due to fan. P: ok. Wind: speed profile looks good. Radiation: normal. Will need to look more closely at sensors with clouds for smaller changes like response time. (T,G,M)soil Gsfc: Good agreement. Msoils: ok. Tsoil: ok. Sonics: normal. NUW1&2 Sample loss problem removed after zeroing process. Both have believable wspd and dir for now anyway. No obsrvance of daylight or temp problem, just seems to be a noisy transducer. NUW1 is beginning to drift. Krypton:OK. fastT: Same. NCAR fast-t is erroneously high bph: OK. Rain: No measurable wet so far. Comments:Some trouble plotting using "geo" coords. Instrument coords. work ok.
Aug 3 Monday Wx: Cloudy, rain in the forcast. High heat index due to higher rh. Base: OK. T/RH: OK. 0.5m,1.5m,4.5m,9m on MegaTurbo aspiration. RH: the OKMN 1.5m/9m agree with each other. NCAR 6.5m is reading less than accurately due to fan. P: ok. Wind: speed profile looks good. Radiation: normal. NRlite has glitch around 0630 today. Same time as our rain event. (T,G,M)soil Gsfc: Good agreement. Msoils: ok. Tsoil: ok. Sonics: normal. NUW1&2 Sample loss problem removed after zeroing process. Both have believable wspd and dir for now anyway. No obsrvance of daylight or temp problem, just seems to be a noisy transducer. Krypton:Some difference between OKMN "H" and ours. Theirs seems low yesterday no obvious reason in sight. OKMN h2o'h2o' field has obvious offset of ~.2 ?? Scott cleaned OKMN krypton today (see entry) fastT: Same bph: OK. Rain: Rain atlast! .25mm at 0630. Rain gauge works!! Comments:
Aug 1 Saturday. Wx: Clear in am, RH ~60% Forcast is same: ~100f, 20% chance or rain. Ground dry as a bone with some cracks. Severe water restrictions in effect. Water smelling and tasting like dirt. Base: OK. T/RH: OK. 0.5m,1.5m,4.5m,9m on MegaTurbo aspiration. RH: the OKMN 1.5m/9m agree with each other. NCAR 6.5m is reading less than accurately due to fan. P: ok. Wind: speed profile looks good. Radiation: normal. (T,G,M)soil Gsfc: Good agreement. Msoils: ok. Tsoil: ok. Sonics: normal. Noticed diurnal sample loss from both NUWs, after zeroing NUW1 the samples remained at 40. While the sample loss for NUW2 stayed below 40 during the day. Will see if sample count returns to 40 for NUW2 after zeroing. UW1 Somewhere on the 31st NUW1 began going out of whack again. After Rezeroing (see entry for sonics) looks good again. UW2 Zeroed after doing NUW1 to see if sample count stays up. So far things look good. Krypton:Some difference between OKMN "H" and ours. Theirs seems low yesterday no obvious reason in sight. OKMN h2o'h2o' field has obvious offset of ~.2 ?? Scott cleaned OKMN krypton today (see entry) fastT: Same bph: OK. Rain: Rain??? hah! Comments:
Aug 1 Saturday. Wx: Clear in am, RH ~60% Forcast is same: ~100f, 20% chance or rain. Ground dry as a bone with some cracks. Severe water restrictions in effect. Water smelling and tasting like dirt. Base: OK. T/RH: OK. 0.5m,1.5m,4.5m,9m on MegaTurbo aspiration. 6.5 using PAM micronel. Penetration depth of vertical orientation appears no more than 2-4cm so we will not reorient the hygrothermometers to horizontal. Reduced winds yesterday caused OKMN sensors to be a bit warmer than respective NCAR. RH: the OKMN 1.5m/9m agree with each other and NCAR 1.5m/9m agree with each other much better than between their respective levels. P: ok. Wind: speed profile looks good. Radiation: normal. See also log message 141 about comparison of rad. Short-Waves: Incoming Epplys have differences up to 20-25 W/m2 day with NCAR higher; 5 at night, hmmm? OKMN being zeroed, NCAR says -5... NCAR SWout is low by about 25w/m**2 peak: possibly shadow effect of rad-stand and cr10 box. Long-Waves: long-waves generally less than 10 W/m2 difference. Net Rad: data has significant differences with 4-component Sums, different spectral response, but also between net rads themselves up to 40 w/m2 between Q7 and NRlite. OKMN 4-comp K&Z CNR1 is significantly different in LW and SWin components. (T,G,M)soil Gsfc: Good agreement. We still don't have a good calibration for the OU Msoil. Msoils: NCAR (CS615s) have not been corrected for their temperature error and show diurnal "peaks", whereas the OU signal is more believable with a hint of "dips" at midday. (consistent with plants drawing down the moisture as they transpire during the day). Tsoil: sensors are reporting significantly different values. NCAR-1 peaks ~4deg warmer in midday and 1-deg warmer at night but consistent with #2 at night. Installation issue or vegetation? NCAR-3 appears shaded in midday and ~1deg cool at night. Sonics: normal. UW1 looks much better since re-zeroing but there were a couple of periods where it didn't agree with the ensemble and appears to be acting up again, so it's still a bit of unknown. Worked ok from ~7/30 10:00 - 7/31 14:00 CDT and for other brief periods. UW2 Steve adjusted the calibration routine, but the virtual heat flux looks inconsistent Momentum flux from both look reasonable and consistent which is nice. Krypton: Same. OKMN still has abnormal high variance evidenced at night. fastT: Same bph: OK. Rain: Rain??? hah! Comments:
July 31 Friday
Wx: Widespread high cirrus, Expecting 30% chance of rain today. Rh higher
Resulting in hazy visibility. High expected to be below 100. We'll see.
Ground dry as a bone with some cracks. Severe water restrictions in
effect. Water smelling and tasting like dirt.
Base: OK. Aster terminal hung up after first look in a.m. Used Xsun in root to kill process.
T/RH: OK. Over the last day or so since MegaTurbo was installed, 4.5m sensor
is showing a cooling trend on the order of 1c. in the day & .5c. at
night. The .5m is about 1c. higher on the average in the day and .3c.
cooler at night before the change in height and ventillation.
P: ok.
Wind: speed profile looks good.
Radiation: normal. See also log message 141 about comparison of rad.
Short-Waves: Incoming Epplys have differences up to 20-25 W/m2 day
with NCAR higher; 5 at night, hmmm? OKMN being zeroed,
NCAR says -5...
NCAR SWout is low by about 25w/m**2 peak: possibly
shadow effect of rad-stand and cr10 box.
Long-Waves: long-waves generally less than 10 W/m2 difference.
Net Rad: data has significant differences with 4-component Sums,
different spectral response, but also between net rads
themselves up to 40 w/m2 between Q7 and NRlite.
OKMN 4-comp K&Z CNR1 is significantly different in LW and SWin
components.
(T,G,M)soil: Good agreement in Gsfc.
We still don't have a good calibration for the OU Msoil.
Our Msoils (CS615s) have not been corrected for their temperature
error and show diurnal "peaks", whereas the OU signal is more
believable with a hint of "dips" at midday (consistent with plants
drawing down the moisture as they transpire during the day).
Tsoil: sensors are reporting significantly different values.
NCAR-1 peaks ~4deg warmer in midday and 1-deg warmer
at night but consistent with #2 at night. Installation
issue or vegetation?
NCAR-3 appears shaded in midday and ~1deg cool at night.
Sonics: normal.
Lost uw2 data about 1400 yesterday. Steve O. changed cal file for UW2
about the same time. Suggest a repair of file.
Krypton: ok.
Krypton agrees well with OKMN except at night when OKMN reads a little
higher
fastT: Same
bph: OK.
Rain: Rain??? hah!
Comments:
About 1000 am the ingest computer for OKMN was disassembled for heat reasons
and this stopped data collection for a couple of hours. Hopefully the data will
be retrieved from the Campbell and added to our data set.
Also Steve Oncley rapaired the error in the NUW2 sonic calculation. Things
look great now.
July 30 Thursday Wx: Same stuff, same forecast: ~105, 20% chance of rain (hah!) OK was declared a disaster area to go along with Texas. we agree. Base: OK. T/RH: OK. See note regarding installation of MegTurbo at ~17:15CDT 7/29 NCAR 0.5m, 1.5m, 4.5m, 9m have MegaTurbo blower. NCAR 6.5m micronel fan.: Clearly reading higher than others. P: ok. Note OKMN pressure sensor doesn't have a static port but it appears that wind effects can be seen in the NCAR data. Wind: speed profile looks good. Radiation: normal.

More errors on 'a' axis and the reported offset was ~1.8. Data from it 'u' ...noisier transducer pair? Other components look pretty good but speed data is crummy. Virtual heat flux is ok, except of course for the noisy UWs. Krypton: ok. Our 9m variance is significantly less (30%) than the 4.5m Krypton, which may be too much to be real. Cleaned Kryptons today ~12CDT. fastT: Normal. NCAR fast-t.4.5m still has ~3.5-deg higher offset. This has apparently been the situation since the beginning. Our fast T still has somewhat less variance than the OU thermocouple. Both NCAR and OU fast-t have somewhat high variances at night. bph: OK. Rain: Rain??? hah! Comments:
July 29 Wednesday Base: OKMN ingest problems: Last night at about the 9:30 record, some bad time tags were inserted into the $ASTER/projects/OASIS98/results/OKMN/980729.ast file: ...NORM,AST05F,"1943-02-05 -3:-32:-9.10655",... This caused Splus and the nc_server to barf and fill the /home partition. when a 77Mb netcdf file was written, oasis.430205.nc Also time stamps on written into the 'regular' oasis.980729.nc file subsequently via the covar process were bogus via the nc_server. Rebooted everything. Back online at ~12:40 CDT. Recreated covar files. Edited OU data, reran. NOTE, the raw ingest and file archive was OK once the ADAMs were back up and only the nc_server covar file stuff really had to be restarted. Also, mxreset did not work to the ADAMS after initially just restarting the nc_server. Gordon edited the "okman.q" function to skip over bad stuff.
July 29 Wednesday Wx: Same stuff, same forecast: ~105, 20% chance of rain (hah!) OK was declared a disaster area to go along with Texas. we agree. Base: Marigold went down overnight: ~7/28 22:00 - 7/29 10:40 CDT Rawort taken down briefly to isolate Marigold problem: ~7/29 9:40,10:40 OKMN ingest problems: See separate message entry T/RH: OK. See note regarding installation of MegTurbo at ~17:15CDT NCAR 1.5m/9m have turbo blower. NCAR 0.5/4.5m/6.5m micronel fan.: Still reading higher than they should.

Comments: Trying to find a change that was made 22 July about the time the tower was dropped. the w'h2o'.prfl data is now significantly lower that the LE data. IS it the changing of the t/rh sensor? The addition of the bigger blower or a monkey in the software calculations?? All are possible. Lets remove one possibility at a time. Anyone with knowledge leading to the culprit should step forward now.
July 28 Tuesday Wx: High RH, some overcast ~40%, to N., Rotated from S at about 4am CDT. ~50 overcast. But forecast is for 103, 20% chance of tstorms.

Rain: No rain. Hydrometors fell in the afternoon! I think I could count them on one hand. Perhaps we should do a calibration just to keep busy? Comments:
July 25 Saturday Wx: Standard weather; hot, Ground beginning to crack due to lack of moisture. Cracks can be 12" long and 3/8" wide. Base: ok. Upon arrival no xwinds, xtemp, or xrh was running. T/RH: OK. NCAR 1.5m/9m have turbo blower. NCAR 0.5/4.5m/6.5m micronel fan. NCAR 0.5m physically at 1.5m P: ok Wind: speed profile looks good. Radiation: normal. Epply short-waves have differences up to 30 W/m2 during the day, long-waves generally less than 10 W/m2. CNR1 is significantly different. (T,G,M)soil: Very good agreement in Gsfc. We still don't have a good calibration for the OU Msoil (I don't think that they do either). Our Msoils (CS615s) have not been corrected for their temperature error and show diurnal "peaks", whereas the OU signal is more believable with a hint of "dips" at midday (consistent with plants drawing down the moisture as they transpire during the day). Sonics: normal. UW sonics rotated at set to 22.5degrees. sigma_w/u* is low from the UWs, perhaps due to spatial averaging. Krypton: ok. Moved 9m cable to OU Krypton for 1hr yesterday. Found noise to still be present. OU krypton probably noisy. Our 9m variance is significantly less (30%), which is too much to be real. fastT: Normal. Our fast T still has less variance than the OU thermocouple. NCAR fast-t.4.5m is still ~3.5-deg higher than bph-T or OUMN-t.4.5m. There is also a diurnal change of this of ~.4deg. This has apparently been the situation since the beginning. bph: ok. Rain: No rain. Hydrometors fell in the afternoon! I think I could count them on one hand. Perhaps we should do a calibration just to keep busy? Comments: Steve leaves today.
We're getting a few sprinkles of rain from a slightly darker cloud right now.
July 24 Friday
Wx: Standard weather; hot, 60% ovcst in am, hey, some possibility
of rain today, high expected once again ~100F. Ground beginning to crack
due to lack of moisture. Cracks can be 12" long and 3/8" wide.
Base: Ragwort was down from ~23:54 until 8:30 CDT today.
Meddling in Boulder (Gordon) was cause of crash.
Initial reboot failed to bring up the sonics: socket problems.
Power down of sonics during boot enabled everything to start.
One NUW had to be encouraged to begin sending data.
10:40 another reboot of ragwort. Cause unknown. This time it came up
without
having to stop the sonics. Note that there was an extraneous cockpit
running which i had to kill; that may have had been a factor.
T/RH: OK.
NCAR 1.5m/9m have turbo blower.
NCAR 0.5/4.5m/6.5m micronel fan.
NCAR 0.5m physically at 1.5m
All NCAR systems oriented vertically
Yesterday the gortex filter was removed from the 0.5m. Results
hint a very slight improvement but not conclusive. Conclusion is
that it isn't a significant improvement.
NCAR 1.5m and 9m equivalent or better than OUMN.
P: ok
Wind: speed profile looks good.
1m prop definitely has shot bearing: wobbles, high resistance/treshold.
Radiation: normal. Epply short-waves have differences up to 30 W/m2 during
the day, long-waves generally less than 10 W/m2. CNR1 is significantly
different.
Nets: OKMN-NCAR Q7 about +10 W/m2 night, -10 W/m2 day.
NRLite and CNR1 differences are -10/-50 W/m2 (night/day) and
-20/-20 W/m2, respectively, referenced to NCAR Q7.
Rsum(NCAR)-Q7(NCAR) is -20 W/m2 night, +/-20 W/m2 day.
Rsum(OKMN)-Q7(NCAR) is -10 W/m2 night, 0 to -40 W/m2 day.
All radiation sensors have much larger differences when clouds are
present. I'm not sure why, given that we are comparing 5-min average
statistics, and the sensor spacing is small with respect to cloud
size. We should keep in mind the different shadow patterns for
the various sensors. In particular, there is a big shadow from
our Campbell logger box which forms just under our Epplys in the
afternoon.
(T,G,M)soil: Very good agreement in Gsfc.
We still don't have a good calibration for the OU Msoil (I don't
think that they do either).
Our Msoils (CS615s) have not been corrected for their temperature
error and show diurnal "peaks", whereas the OU signal is more
believable with a hint of "dips" at midday (consistent with plants drawing down the moisture as they transpire during the day).
Sonics: normal. K-probe losing up to 0.5% of samples during the day, which
is acceptable. UW-probes losing up to 3% during the day. CSAT has
been better than the K-probe according to cockpits. Statistics from
UWs have been bad during to spiking, despite setting "despike" in
prep.config.
spd agrees within 0.2 m/s (except at 9m, obviously), dir to within
2 deg. H between NCAR-OKMN at 4.5m is within 30 W/m2 - pretty good.
NCAR H at 9m is larger than at 4.5m - this doesn't make physical sense
and could indicate significant path averaging at 4.5m??
LE from NCAR 4.5m is larger than both 9m and 4.5m OU. This makes
physical sense in the case of 9m, and indicates inadequate sampling(?)
in the case of OU.
sigma_w/u* is low from the UWs, perhaps due to spatial averaging.
Krypton: ok. I still think that the OU krypton is noisy. Our 9m variance
is significantly less (30%), which is too much to be real. Perhaps we
need to clean again?
fastT: Normal. Our fast T still has less variance than the OU thermocouple.
NCAR fast-t.4.5m is still ~3.5-deg higher than bph-T or OUMN-t.4.5m.
There is also a diurnal change of this of ~.4deg. This has
apparently been the situation since the beginning.
bph: ok.
Rain: No rain. Perhaps we should do a calibration just to keep busy?
Comments: We trade Cathy for Tony today.
July 23 Wx: Standard weather; hot, sunny, etc. Base: We had a quick adam reboot yesterday when OG&E pulled our electic meter - everything came back okay with no human intervention. Gordon has restored xwinds and xtemps - I never realized how much I like having them around. T/RH: Lots of stuff happened yesterday - see separate messages. Our philosophy is to make 1.5m and 9m as good as possible, move 0.5m up to 1.5m to allow us to test alternate configurations, and leave 4.5 and 6.5m in the old configuration until we can come up with something better. John is moving the 0.5m now (08:25), and will rotate it 120 degrees around the tower. The blower is now on just 1.5m and 9m andboth T and MR agree with OU from yesterday evening and last night. I don't know a physical mechanism which would cause MR problems, but would be cleared up by increased aspiration. John also removed the GorTex shield on the old 0.5m sensor to try to isolate this problem. On the positive(?) side, I think that most of these problems were induced by vertically orienting the T/RHs last week. The profile differences were less when the intake tubes were horizontal. In other words, the biggest differences between the passive (OU) and fan-aspirated systems are in strong winds with vertical tubes. We might have been fine in the present strong southerly winds if we had left the tubes horizontal pointing South! P: ok Wind: speed profile looks good. However, I've just noticed that the 1m prop was stopped even though the wind was strong enough to move the vane. Thus, the 1m prop bearings may be getting bad. Directions differences are mostly within 2 degrees. In orienting John, I was reminded that we should pay attention to bent vanes. Radiation: normal. Epply short-waves have differences up to 30 W/m2 during the day, long-waves generally less than 10 W/m2. CNR1 is significantly different. Nets: OKMN-NCAR Q7 about +10 W/m2 night, -10 W/m2 day. NRLite and CNR1 differences are -10/-50 W/m2 (night/day) and -20/-20 W/m2, respectively, referenced to NCAR Q7. Rsum(NCAR)-Q7(NCAR) is -20 W/m2 night, +/-20 W/m2 day. Rsum(OKMN)-Q7(NCAR) is -10 W/m2 night, 0 to -40 W/m2 day. All radiation sensors have much larger differences when clouds are present.

July 22 Wx: Standard weather; hot, sunny, etc. Base: System Up. Cockpit Displays: OK. T/RH: Temperature profiles look ok. NCAR Rad. shields have radiation induced errors in daytime compared with OUMN. Delta 1.5m ~.4deg, 9.m ~1deg. Blower Added:...see separate message for details. MR profiles Steve said they are not monotonic and he doesn't know why. Two observations, first the OUMN MR with respect to NCAR shows the diurnal effects of the NCAR radiation shield: why? Shouldn't the MR be unaffected and have the temp./rh induced shifts cancel? Second the profile of the 4.5m vs 9.m is not ordered as Steve mentioned. Which is the culprit, looks possibly like the 9.m which doesn't show a slight drop as night comes on. This may be related to the aspiration issue. will look more tomorrow with improved 9m ventillation. P: ok Wind: ok Radiation: ok. Still see a 20 W/m2 bias in CNR1a long-waves. Tony has been making seperate entries on his observations. (Use robust=F!) (T,G,M)soil: Very good agreement in Gsfc. We still don't have a good calibration for the OU Msoil. Sonics: normal. nuw1 statistics bad due to spiking. (I thought I'd fixed that using "despike"?). There seems to be a bit more spiking on the 4.5m sonic, esp. indicated by the reduced number of samples being averaged into the 20hz readings. Krypton: ok. I still think that the OU krypton is noisy. Our 9m variance is significantly less (30%), which is too much to be real. Perhaps we need to clean again? fastT: Normal. Our fast T still has less variance than the OU thermocouple. NCAR fast-t.4.5m is still ~3.5-deg higher than bph-T or OUMN-t.4.5m. There is also a diurnal change of this of ~.4deg. This has apparently been the situation since the beginning. bph: ok. Rain: No rain. Perhaps we should do a calibration just to keep busy? Comments:
A guy doing soil moisture measurements drove up about 10 min ago (~9:50) just to the east of the OU tower with his truck. (He first parked to the south and I told him to move from being directly upwind of the OU sonic.) He says he'll be here for "quite a while". Data from this morning should be used with caution - especially radiation data. Of course, he also put a set of tracks through the grass directly upwind. I couldn't catch up to him by running - sorry! (I gave him a bit of a lecture on site discipline at OASIS (rather than normal mesonet) sites, but I don't think it sunk in.) P.S. "Nathan" left at 11:28.
July 21 Wx: Standard weather; hot, sunny. Forecast is for 104 today. The extended forecast is to get below 100 on the day I leave! Base: System backup done yesterday - probably won't have to do it again. T/RH: Temperature profiles look ok. MR profiles are not monotonic - I don't know why. We are waiting for the blower to arrive today with John to implement better aspiration. P: ok Wind: ok Radiation: ok. Still see a 20 W/m2 bias in CNR1a long-waves. Tony has been making seperate entries on his observations. (Use robust=F!) (T,G,M)soil: Very good agreement in Gsfc. We still don't have a good calibration for the OU Msoil. Sonics: normal. nuw1 statistics bad due to spiking. (I thought I'd fixed that using "despike"?) Krypton: ok. I still think that the OU krypton is noisy. Our 9m variance is significantly less (30%), which is too much to be real. Perhaps we need to clean again? fastT: normal. Our fast T still has less variance than the OU thermocouple. I still wonder if we should try making a better probe. bph: ok. Rain: No rain. Perhaps we should do a calibration just to keep busy? Comments: I've created a small file of the commands I've used to create plots to address the status issues. I'll give this to John and Cathy.
July 19
Wx: Standard weather; hot, sunny.
Base: Data backup on Sunday evening. Data capacity from 9% to 15% overnight
T/RH: still radiative heating effects, Checked local ACE HARDWARE has all the
fittings and pipe to outfit a big aspirator. Will have John or Cathy bring out
a turbo blower..
P: ok
Wind: Profiles of Spd/spd and Dir/dir show differences between prop and
sonic results
Radiation: Picked Jul 14 18:00 - Jul 15 18:00 as the most perfect radiation
day and plotted comparisons between all radiometers.
(T,G,M)soil: Have noted significant differences between corer and pit and clod
gwf and bulk densities.
Sonics: See "Winds". All sonics working. UW2 ran all night without spiking
but UW1 did spike .
Krypton: ok.
fastT: ok.
bph: ok.
Rain: No rain
Comments: The soil moisture is at ~4% gwf and doesn't seem to be decreasing
further. Have asked Steve S to send out turbo pump.
.
July 19 Wx: Standard weather; hot, sunny. Winds back to a southerly regime. Temps were back above 100F yesterday. The paper said 102 for today also. Base: ok T/RH: still radiative heating effects, especially in stronger winds. Tony is working on it. P: ok Wind: ok Radiation: ok (T,G,M)soil: ok? Sonics: ok. same amounts of spiking. I'll try to measure the arrays today. Krypton: ok. fastT: ok. bph: ok. Rain: No rain Comments: I've just looked at the whole month's worth of data. I've found that Tony and I have been here during the hottest period! (Fortunately, we've been able to stay inside a lot.) I don't understand what is happening with water. The field still has a fair amount of green plants. (I would guess an LAI of green vegetation of about 1, and of brown vegation another 1. Tony guessed the same. We've taken some photos to document the state.) However, the root zone appears to be only 6 cm when we dig up clods and the soil moisture in this layer doesn't appear to be changing. Furthermore, the latent heat fluxes have been getting to 200 W/m2 through the month, with little trend. There are only 2 interpretations I've come up with: 1. Water is diffusing upwards from a deep reservoir to maintain the same water potential, balancing the transpiration loss from plants. 2. Water transpiration is dominated by a few plants with deep roots. I think this to be unlikely given the relative uniformity of the green surface cover. Perhaps we should dig deep someplace to map the moisture profile. (If we can break through!)
We just got back from a day of getting stoned (we visited 2 quarries), but everything appears to have worked fine in our absence. Good night.
July 18
Wx: Standard weather; hot, sunny. Presently clear, with low-level haze.
Winds light and southerly. Winds were light and easterly (and variable)
yesterday.
Base: No problems. Scott brought 8 visitors from the university including
the director of the mesonet and Doug Lilly. I also hosted Jeanne Schneider,
who may be interested in looking at the soil moisture data.
T/RH: Yesterday afternoon we gerry-rigged the vacuum cleaner to the T/RH at
1.5m in order to increase its aspiration. It appeared to help, with our
temperatures during the test about 0.3 C lower than OU, though we didn't run
it for long (we turned it off overnight). Also, our temperatures were
generally lower anyway during the light winds. We'll continue this
test today. Tony switched it back on at 9:00.
P: good. Note that dat("P") now uses my temperature correction on our sensor
and appears to work on new data, implying that the correction is constant.
Wind: Spd and Dir profiles look OK. OU cups are low - I think that they
were going to replace them yesterday, but I lost track of whether they did
with all the visitors.
Radiation: I've looked at the shortwave, longwave, and net rad time series
for the last week. All of the OKMN sensors generally are within 20 W/m2 of
ours, with a strong diurnal signature. However, the CNR1 sw.in is up to
60 W/m2 lower than ours, and both lw.in and lw.out appear to have a bias
of about 20 W/m2. The resulting CNR1 Rnet only has differences of 30 W/m2
from our Q7. The NRLite Rnet has differences of up to 50 W/m2. You get
what you pay for!
(T,G,M)soil: The computation of Gsfc shows that most of the differences
between our Gsoil measurements is compensated by Ssoil, so that Gsfc agrees
to within 10 W/m2! It is obvious from the data that .1 was significantly
different from the other measurements before Tony reburied it. The OU sensors
are different by as much as 50 W/m2 during the day. Presumably, this is due
to a slightly different albedo at their "plot" about 15 m away which would
effect the local net radiation. Of course, any of the other energy balance
terms also could be locally different.
Sonics: The CSAT has been spiking the least (typically 4/day). The ATIs have
both been spiking somewhat more (30/day?) during the heat of the day.
The UWs have been spiking significantly, with 3-10% loss of raw samples during
high temperatures. Presumably this is caused by the longer pathlengths.
I don't trust the UW array geometries. Currently, we are using the default
of 60 degrees for all angles, because I haven't measured them. Through the
theodolite, it appeared that the UW2 array was twisted somewhat, though the
zero calibrations indicated that the pathlengths were nearly perfect.
Obviously, I should measure the geometries, but haven't figured out how to
do it. [I can't use the "dummy transducers" that we built up for the old
UWs and ATIs, since they screwed in and the new transducers aren't removable.
Also, I don't have a set of calipers out here, though I should be able to
borrow one from OU.]
Krypton: ok. O.
fastT: ok. .
bph: ok.
Rain: No rain
Comments: Meltponds slowly increasing in size and number.
July 17
Wx: Standard weather; hot, sunny
Base: No problems.
T/RH: Comparison of NCAR aspirated TRH with OKMN behives: Dispite the changing
of the intakes of the TRH from south facing horizontal to down pointing,
the NCAR T > OKMN T. In fact there is no significant difference from the
previous situation. Looking at the data from the horizontal intake period
it is probable that there were wind speed.direction effects.
P: ok.
Wind: Spd and Dir profiles look OK
Radiation: Yesterday an intercomparison of the radiation systems was started.
(T,G,M)soil: The order of the soil T s has been changing.
Ssoil is now available, thanks to Steve's diligent coding.
Sonics: The uw1 and uw2 are up and running. The angles for the two sonics were
shot with the theodolite .
Krypton: ok. O.
fastT: ok. .
bph: ok. Look reasonable -.
Rain: No rain
Comments:
July 16 Wx: Yesterday morning was a nearly cloudless day,with shifting winds from the north. Today is hazy.. . Base: Last night a series of difficulties occured 19:17: Aster reboots, cocklebur can't access disk. Maybe a power problem? 20:10: Aster reboots again. Why?? 23:32: Adams reboot. This could have been Gordon attempting to fix the system. 23:37: Ragwort crashes. SerialSock gives ECONNRESET error.

It is possible that the difficulties were instigated by power failure(s) which managed to penetrate the UPS protection. First thing this morning the serial channels to ragwort were disconnected and later reconnected. The reporting rata for the two UW sonics was reduced to 5 Hz.

The two UW sonics have been added to the array, but they had been on-line, on and off, for almost two days without any difficulty occuring. . T/RH: The Ts reported from the NCAR aspirated TRHs appear to be systematically lower than for the OKMN bee-hives.

Graphic: 
July 15 Wx: Clear, a bit hazy. Slightly cooler than usual. Light winds from E. Base: Still floundering with dat code for soil. Found that the constants we are using for the OU moisture aren't working (giving NAs). Jerry is checking. Last night started work processing OU Bowen ratio measurements, ultimately to yield w'h2o'.prfl. Got pretty far, but saw a sign reversal problem. Jerry will check on this also. Also created dat.azimuth which reads a file of sonic boom angles. dat.dir still isn't picking this information up properly. T/RH: No T/RH reporting problems since I replaced the HC11 board. The NCAR sensors do have large (0.5 C) radiation errors during winds with a northerly component. See the graph of T NCAR-OU vs. north wind component attached to this entry. Both 1.5m and 9m show this trend. P: ok. I've created a dat.P with my temperature correction so that we can check if the temperature dependence is constant. It gets the magnitude of the pressure variation better, though there still is a large phase shift between the NCAR and OU signals. Wind: ok. Spd profile looks good. NCAR speeds are greater than OU. Radiation: pretty good. (T,G,M)soil: ok. See Tony's extensive comments elsewhere in this volume. Sonics: Yesterday was a big day! All sonics are now operating, though we need to zero the UWs and work on their calibration routine. That's the first task for today. Krypton: ok. OU cleaned theirs 2 days ago, so the means are now closer and the variance is smaller (though there still appears to be a noise floor at night.) The fluxes never were too bad between their system and ours. fastT: ok. Variance from OU's is somewhat higher than ours, which could be either (or both) spatial filtering of our signal or noise on theirs. bph: ok. Look reasonable - lower variance than fast sensors, but same shape. Rain: No rain Comments:

He talked to Gordon and discussed Neechee(or something like that). A scheme to apportion the soil Ts, G, and Ms was devised. I will run the soil energy budgets today and see whether the scheme is good. T/RH: Again, TRH at 1.5m was dead this morning. It will be replaced with the spare. T and RH profiles look good P: ok.

Sunday, July 12 [We're planning to only work this morning, since the OU people also won't be here today (Jerry and Chris were here yesterday). We had fun last night finding flaws in "Armagedon" (sp?).] Wx: Sct Cu now - could be another warm one. Winds still southerly yesterday, but generally pretty light. Currently they are from the NE. Base: I've just bkfiles_kill'ed, so we're now down to 21%. I also took several pictures with the digital camera yesterday of the sensors and created a skeletal WWW site on stout with them. I've made a color-coded idraw of the dat objects. We still have some configurations to play with - I'm waiting to talk to Gordon to discuss philosophy. T/RH: TRH at 1.5m was dead this morning. See previous logbook entry. We're not reading RH from OKMN. Perhaps we should. P: ok. Wind: ok. Why aren't the OU data plotted when asking for "Spd", but are when asking for "Spd.2m"? Radiation: ok. There was a full moon 2 nights ago, but I don't think we can measure it! (Tony says it is 10^-6 of sunlight, or 1 mW/m2.) (T,G,M)soil: ok. Gsoil.1 now fits in with the rest. Tsoil.1 NCAR agrees with Tsoil.1 OU and Tsoil.2 NCAR agrees with Tsoil.2 OU, but not with Tsoil.1. This has to be coincidence, since the sites are not colocated. Sonics: UPS didn't deliver the new transducer for ati.9m because they needed a signature and didn't get one from the front desk!@$#! I guess we'll have to wait until Monday. ati.4.5m and csat.4.5m have worked pretty well, with only a few spikes appearing on cockpit. Statistics look reasonable when plotted as a time series - scatterplots may show differences. One of the UWs was sent to ATI to get an EPROM upgrade (I think). Hopefully, this will allow us to use it for a 20cm path. Krypton: ok! Suggested that the OK sensor to be cleaned, since h2o'h2o' looks terrible. Their voltage channel shows 30 V, which obviously is wrong. I could believe 30 mV, which is too small for normal operation. However, the fluxes don't look too bad. fastT: ok. bph: ok. mr.bph variance agrees pretty well with h2o variance! Rain: No rain Comments:

Saturday, July 11 Wx:Yesterday was hot, similar to the weather for the whole of the week. In the afternoon grey cumulus developed but there was no rain. The remnats of the soil dampness was gone. This morning is partially overcast. Base: Yesterday cocklebur was down when we arrived. It was brought up but low-level problems persisted, slow response, difficulty in finding data. Steve spent a portion of the afternoon re-ordering the access to soil parameters. He has cleaned up the system, killing processes. Sent all marigold and some ragwort files to NCAR. T/RH: Profiles look OK. Note: after the rain the gradients of RH increased P: See logbook # 103. Wind: Profiles of Dir and Spd look OK. . Radiation: ok The Rsw negative fluxes of ~ 3 - 5 Wm-2 during the night-time are, apparently, a real instrumentation response. The sensor exports a small energy flux throughout the night. See logbook # 85. (T,G,M)soil: Gsoil.1 is an outlier with too small a magnitude, but the difference is closing. . Sonics: 9m ATI was been brought into trailer. One of the u transducers was temperature sensitive, generating a weak signal. It was removed and ATI will FEDEX a replacement. A method for the re-stringing the transducer coax was developed. Hopefully we should be able to make a field replacement of the transducer. The UWs are to be sent to ATI Krypton: ok! Asked for the OK sensor to be cleaned fastT: ok. bph: ok. Rain: No rain Comments: ADAM temperatures top out at ~ 35 degreeC

We spent today figuring out how to repair the 9m ATI. Herb is sending out a new transducer tomorrow, and we'll try to replace it in the array. We also worked a bit on software, trying to get Gsfc running, along with some nuisance software issues resolved (mostly failed). check_aster has been normal, except for 2 nc_server processes (we killed one). cockpits have been okay. Otherwise, we didn't do any QC checks today. backup was done. I'll kill the files when I return tonight (we're now at 93%) to allow me to try to FTP them to Boulder. The data rate was 14 K/s earlier today, which was a bit slow for this much data.

Thursday, July 9 [Sorry for missing a few days - the need to do a daily status got lost in the transition from Tom to me. See other entries for significant events.] Wx: Broken Cu, winds light and westerly (at the moment) Yesterday's winds also were quite variable. The ground also is moister (and slightly greener) following the rain early yesterday morning. Base: ok. The adams rebooted in the electrical storm 2 nights ago, but came up by themselves. The RF network modem was swapped out by Stan 2 days ago since it was too powerful (500, rather than 100 mW). It then died during the electrical storm, but came back after cycling power and waiting about 1/2 hour. T/RH: Profiles still are a bit strange. See logbook #94 for some details on playing with RH and T biases. P: Still see heating effect. We should try radiation shielding today. Wind: Speeds ok. Flipping the vane at 2m 2 days ago helped make the directions consistent. Flipping the vane at 6.5m appears not to have helped. Radiation: ok. Tony and Tom have been looking into Rsw negative fluxes of ~ 3 - 5 Wm-2 during the night-time. (T,G,M)soil: Tony dug up and replanted T probe and G plate site #1 2 days ago, since Gsoil.1 was an outlier (too large magnitude). Fortunately, it rained about 9 hours later to help "set" these sensors. However, Gsoil.1 is now an outlier with too small a magnitude! Tony will keep on looking at this. Sonics: 9m ATI U is spiking heavily during the heat of the day and improves at night. V & W are behaving well. Cooling the boom (and thus electronics) with a wet towel 2 days ago may have helped somewhat, but didn't eliminate the problem. We've also seen spikes on 4.5m ATI, though not as bad. The OU CSAT has given a few spikes, but not as many as the ATIs. The UWs are now built, but not working. (Both were operated for a few minutes yesterday giving -99.99.) I'm trying to isolate this problem. Krypton: ok! (even though it rained 2 days ago) I cleaned both of ours 2 days ago, which changed the offset by about 10 g/m3, but the gains appear to be the same. Variance of 9m is lower than 4.5m (as expected) and also larger after the rain (as expected). Variance from the OU sensor is too large - I wonder if this is noise? (And/or if it should be cleaned?) fastT: ok! (worked through the rain) Variance from ours is still less than from the OU CSI thermocouple. bph: ok. Rain: ok. There were 2 events in yesterday morning's rain. The first, both OU and NCAR show about 6 mm of rain. The second OU shows 89 and NCAR 64 mm. There also is a time shift (NCAR late by 5min), which apparently has been known. Comments:
- 98: LOG, Site NCAR, Wed 08-Jul-1998 08:09:57 CDT, lots of rain last night
There was a thunderstorm about 3:30 last night (it woke us up in the motel! There are some puddles around the site. The OU network went down, so we are unable to look at OU data. Stan is working on it. The ADAMS apparently rebooted themselves during the storm - probably due to lightning. I didn't know they would do that! All sensors appeared to have survived: 1. NCAR Fast t works and shows a 5 degree drop, along with the slow Ts. 2. NCAR kryptons got wet, but dried in 1-2 hours. Perhaps their offset (difference from hygrothermometers) has changed by 0.5 g/m3). [Note that their offset is now negative, which may indicate that we are using the "scaled" calibration.] 3. Soil sensors record the moistening and increased cold flux into the soil as expected. The soil Ts show a cold pulse during the rain, and then settling back to the general nighttime cooling trend. All this is normal. Tony is very glad that he [had the foresight to] reinstalled the sensors at site #1 just before this wetting event. Also note that this site did not record the most moistening, so he didn't disturb the soil too much.

- 44: LOG, Site , Sat 27-Jun-1998 09:50:55 CDT, NCAR/OKMN comparisons
We are now ingesting OKMN data and I note the following comparisons: Temperature: 1.5m and 9m temperatures agree within better than 0.1 C at night, but NCAR temperatures are 0.1-0.2 C cooler during the day. The difference is smaller at 9m than at 1.5m, consistent with a wind-speed-dependent radiation error in the OKMN shield. As a consequence, T(9m) - T(1.5m) is greater (more positive) for NCAR than for OKMN, by 0.05-0.1 degC during the day and 0 to 0.05 degC at night. Winds: NCAR winds speeds are 10-20 cm/s higher than OKMN at both 2m and 9m. A 48-hour average, June 26 (1030 CDT) -28 (1030 CDT), gives NCAR OKMN NCAR-OKMN 9m 7.080 7.014 0.066 m/s 2m 5.468 5.440 0.028 m/s 9m-2m 1.612 1.574 0.038 m/s Pressure: There is a 1-2 mb difference between NCAR and OKMN which suggests a temperature contamination of one of the barometers. The error decreases as shadows from the prop and sonic towers pass across the NCAR barometer enclosure, indicating a temperature error in the NCAR barometer. Rsw.in: NCAR > OKMN during day by 10-20 W/m^2 OKMN = 0.985*NCAR + 2.3 W/m^2 Hysteresis in the xy plot suggests a leveling difference. NCAR ~ -3 W/m^2 at night; OKMN = 0 Rsw.out: NCAR < OKMN during day by 10-20 W/m^2 OKMN = 1.1*NCAR + 1.0 W/m^2 This difference may be affected by the albedo. It appears that the surface under the OKMN pyg is "brighter" than that under the NCAR. NCAR ~ -1 W/m^2 at night; OKMN = 0 Rlw.in: OKMN = 0.973*NCAR + 10.4 W/m^2 But the xy plot is noticeably non-linear, again with hysteresis suggesting a leveling difference. Rlw.out: No OKMN data; Tcase.out and Tdome.out missing Rnet: NCAR > OKMN during day by up to 25-30 W/m^2 NCAR < OKMN at night by about 10-15 W/m^2 Rnet.OKMN = 0.944*Rnet.NCAR + 8.74 W/m^2 Rnet.OKMN is REBS SN# Q96101 from NCOM Sonic: u.NCAR = 0.97*u.OKMN + 0.015 m/s v.NCAR = 0.93*v.OKMN + 0.72 m/s u'u'.NCAR = 0.91*u'u'.OKMN + 0.017 (m/s)^2 v'v'.NCAR = 0.93*v'v'.OKMN + 0.010 (m/s)^2 w'w'.NCAR = 1.10*w'w'.OKMN + 0.002 (m/s)^2 u'w'.NCAR = 1.38*u'w'.OKMN - 0.007 (m/s)^2 v'w'.NCAR = 0.64*v'w'.OKMN - 0.034 (m/s)^2 u*.NCAR = 1.14*u*.OKMN + 0.022 m/s tc'tc'.NCAR = 0.99*tc'tc'.OKMN - 0.002 (degC)^2 w'tc'.NCAR = 1.13*w'tc'.OKMN - 0.003 (degC)^2 June 29 Found that the ATIs were tilted by about a degree in one direction and the Campbells about a half degree in the other. This appears to explain about 2/3 of the differences in u* and w'tc'. See logbook entry #50. Note that tc'tc' is in good agreement, suggesting neglible (or canceling) errors due to covariance calculations or differences in high-frequency sampling.
