160 BB 19:20:00 20:20:00
Disassembled sampler-pulley system and datalogger for adjustments to two
sampler levels, equal vacuum tubing lengths, and for attachment of critical
orifices to all sampler units. Will return June 23.
Return to Richland unload and set-up sampler holder June 23
(JD 176 GMT 02:00-05:00) Now using two sampler heights, 2.5 meters and
8 meters. All flowmeters recalibrated and samplers are being rotated
into different positions to eliminate a "sampler/position effect".
All tubing equal length to eliminate "height/flow effect".

BIO FLUX:
The bioflux data logger provides
2 output signals. These have been setup for
temperature measurements at 8m and 2m on
channels 104 and 106, respectfully.
Data are now coming in @ 03:00Z.
- 95: BUGFLUX , Site none, Fri 12-Jun-1992 18:08:41 GMT, Bioflux data requirements
Bioflux data requirements
The bioflux program is designed to measure the surface flux of
viable micro-organisms.
Bruce and Brenda take 30 or 60 minute impactor samples at different
heights on their tower. They need the heat flux and the temperature
gradient data from the cosmos flux and psychrometer towers in order
to calculate their fluxes.
Ht flux = overbar(w't') = K Cp rho Dt/Dz
Bioflux = = K Dbio/Dz
Bioflux = overbar(w't')/Cp rho (Dbio/Dt)
For the days which they collected impactor samples we should provide
the covars for :
wt
tdry.psyc.1.5m
tdry.psyc.3m
tdry.psyc.5m
tdry.psyc.7.5m
tdry.psyc.10m
This should be printed out numerical data.
Six parameters with 288 values each for each of the 10 or so days
that they operate.
- 152: BUGFLUX , Site none, Sat 27-Jun-1992 02:23:14 GMT, Added the bioflux 1-D sonic and fast t
Added the bioflux 1-D sonic and fast t to cosmos
Installed 20hz filters for these channels in the filter board on cosmos.
The sonic signal coming out of the Campbell 21X datalogger was very ugly,
with much jitter, so the Aster data connection is at the input of the 21X and
looks OK. The output voltage of the sonic is +-5V with 1V=1m/sec. The
channel is configured with gain=0.
The fast t seems to be broken, the output is fixed at around -2.8 V.
Cosmos was down for this work from 15:57 (22:57 GMT) to about 17:00 (00:00).
