- 284: KRYPTON/IR/none Wed 07-Sep-1994 02:06:39 GMT h2o.AA.7.5,.flux looking very wild today
cockpit shows complete noise on this channel at some time
during the day, although it looks clean now. It could have
been this morning when the cloud was passing through.
- 293: KRYPTON/IR/none Thu 08-Sep-1994 17:50:30 GMT AA hygrometer down this morning
The AA IR hygrometer wasn't working this am.
There was rain and cloud overnight,
charlie recyled power and it started producing signal again.
spectra indicate no information beyond 1 Hz at best.
- 294: KRYPTON/IR/none Thu 08-Sep-1994 18:03:39 GMT AA restarted
Just by cycling the power
- 319: KRYPTON/IR/none Mon 12-Sep-1994 23:01:13 GMT Moved IR hygrometer to 10m
After talking with Rick Vong and Herb Zimmerman, moved the IR hygrometer
on loan from ATI from 7.5m to 10m. It was turned off from ~2030 GMT until
~2200 GMT. We mounted its boom on the nominally west face of the flux
tower so that its boom was parallel to the sonic v axis. The hygrometer
is now ~18 inches higher than the 10 m ATI sonic and ~36 inches east of
(behind) the sonic v axis. The hygrometer is within ~8 inches of the
tower.
- 322: KRYPTON/IR/none Tue 13-Sep-1994 18:22:52 GMT h2o.AA.10m.flux covar and archive changes
h2o.AA.7.5m.flux is now h2o.AA.10m.flux, reflecting its raise in prominence.
It is now being covar-ed in the 10m flux group, so we can
use it for latent heat flux.
It is also now being archived in flux/fast, instead of flux/irAA.
sonic.config.S has been updated to reflect this change, and also to remove
the Campbell krypton hyrometers.
- 337: KRYPTON/IR/none Sat 17-Sep-1994 18:29:01 GMT Extended 10m AA IR hygrometer boom
In order to reduce the possible flow distortion from the tower at the
location of the fast IR hygrometer at 10m, extended the boom further
out from the tower. It is now about 16 inches out from the side of the
tower. This change occurred around 11 am PDT.
