Remote Site is setup 
 
Remote site is operational on the slope of  
Watch peak at a height of 200 m above sea 
level. At the moment relativ humidity,  
temperatur and net radiation are measured. 
The data acquisition rate is 6 sec. averaged 
to 1 minute data. 
Time is set to GMT synchronized to the ASTER 
unix computer time. 
Start data logging was 18:30 1994 Aug 7 (219)  
GMT. Data are going to be available after the 
next visite of the remote site.  
 

Flux tower stabilizing bboom afixed 
 
15:00-16:00 Monday 8 Aug a 3m stabilizing boom was afixed 
to the flux tower at approx the 12.5m height. The ends 
of the boom were guyed to the behind dumpling 
 

Remote site data in ../results/remsite/ 
 
Remote site: 
 
   Location of remote site: 
   On the slope of watch peak at an elevation of ca. 204m. 
 
   Measurement of a Vaisaila RH probe and net radiometer with 
   a Campbell CR-10 data logger. A wind monitor is going to be  
   setup later in CACHE3. 
   Readings occur every 6 seconds, the data are averaged to 1 minute 
   values.  
    RH.1min = sum(RH.6sec)/10 
    T.1min = sum(T.6sec)/10 
    NetRad.1min = sum(NetRad.6sec)/10 
    WS.1min = sum(WS.6sec)/10  
    WD.1min = arctan(Ux/Uy) 
              Ux=sum(sin(WD.6sec))/10 
              Uy=sum(cos(WD.6sec))/10 
    WDdev.1min = arcsin(eps)*[1+0.1547*eps^3]  "Yamartino algorithm" 
              eps=sqrt(1-((Ux)^2+(Uy)^2)) 
              Ux,Uy see above 
 
 
Data format: 
   Each line contains the data of the last minute, separated by  
   commas. 
     id,jday,hhmm,secs,T,RH,WS,WD,WDdev,NetRad 
      id = CR10 storage id number (no special meaning) 
      jday = julian day 
      hhmm = hours and minute in hhmm format (GMT) 
      secs = seconds in ss.ss format 
      T = Temperatur in C 
      RH = relativ humidity in % 
      WS = wind speed in m/s 
      WD = wind direction in degree 
      WDdev = wind direction standard deviations 
      NetRad = net radiation in W/m2 
 
Data files: 
 
RS220226.DAT  
  Start: jday=220, hhmm=0302; 08/08/94 03:02 GMT  
  End  : jday 226, hhmm=1757; 08/14/94 17:57 GMT 
  From 220, 03:02 until 225, 16:55  
    There are RH, T and NetRad data available. WS, WD, WDdev are not valid. 
  From 225, 16:56 until 226, 17:57  
    Only NetRad is valid. 
 
 

Remote site has a wind monitor now 
 

Air Condition tries to be a musician 
 
Air Condition in the ASTER trailer gives off some 
strange noises. I think it is the ventilator. 
I turned it off at 11:49 GMT. 
 
 

boomdir.seat is a few mV low 
 
Before 237, 2:09 GMT: 
Boom cshow reading is 1.2mV low  
 
Changed boom: 
237, 2:09 GMT boom set to 269, (268.4mV) 
cshow gives 266.6mV

Forrest fire to the southwest, road closed until 0930 this 
morning 
 
 

La Pooh 
 
The La Pooh truck was just here. 
Andy, Tris and Peter are now happy campers again ;-)
 

The alternative to metalog!

from crossarm to tower to ground stake next to 
container. This has cleared up the noise
in atik.10m.walk

Although fresh memory and batteries were taken to the remote site on Sun/Mon pm
the program apparently was NOT restarted. I will go down later this pm if
possible to do so. Kim's NaOH bottles are being dispersed at 5 pm today fopickup Wed.
