VOLTAGES/CURRENTS voltages ok. Florida's load current dropped due to
removing 4-component and fan for diagnosis on board the ship.
TBOX: got a bit warm as the stratus passed over and the ambient air
temperatures rose.
TRH: ok. Warmer temperatures correspond to thick stratus passing over.
4-COMP: Atlanta and Baltimore domes probably rimed over. Gap in Florida data
due to bringing 4-component indoors for diagnosis.

HFT: Sudden increase in Gsoil at Cleveland. Earlier in day had instructed
Jumper on how to clear instruments of rime if/when he

Installation manual says to install temperature sensor over
flux plate. If this was done, why wasn't there a change in
Tsoil?

4-COMP: Did more testing on Florida's 4-component. Tried disconnecting one or
more radiometers at a time to see possible influence on pyg dome
temperatures. Found that with pyg.in disconnected, other 3
radiometers gave good output. When pyg.in cable is reconnected, both
pyg dome temperatures develop a positive offset. Asking NCAR folks
for permission to open pyg.in and inspect wiring.
PRESS: ok
TSOIL: ok
HFT: Gsoil output from Cleveland more variable than other sites. Possibly
due to footprint near sensor causing greater influence from varying
air temperature.
SONICS: High winds and warmer temperatures cleaned frost off sonics.

"Visited" Florida. Light snow cleaned off domes, on downwind side.
No frost on sonic. Fresh layer of snow all around; no
footprints from previous visits. Changed propane. Old
tank weighed 35#, so still had 12.5# of propane in it.
Chose not to change flash card this time.
Visited Atlanta. Light snow cleaned off domes. Fresh layer of snow
all around; no footprints. Changed propane and flash card.
Old tanks weighed 25 and 42 #s, so still had 22# of propane.
No frost on sonic thanks to recent storm/wind.
Intended to visit Baltimore and possibly Cleveland tomorrow, but
a large lead opened up near the ship. The trail to
Baltimore includes 300' of water/slush. The trail to
Cleveland hasn't been checked all the way, but the view from
the bridge shows it may well be inaccessible as well.
VOLTAGES/CURRENTS: ok
TBOX: ok Interesting how box temps vary between sites.
TRH: ok. Cleveland temps don't follow quite the pattern the other 3 sites do.
During Atlanta site visit, Chris Fairall placed Vaisala
handheld temperature/humidity sensor that ETL uses as an
intercomparison standard near intake of TRH. At 22:40 he
read -14.1C, and 84% relative humidity.
4-COMP: pyg.in still disconnected at Florida. ~22:00gmt, replaced pyg.out
cable with pyg.in cable to test pyg.in cable. ~02:00gmt,
transfered pyg.out cable to pyg.in bulkhead connector on
CSI black box.
Not concerned with levels on Florida's 4-component until pyg problem
is solved. Level cable remains unattached.

duster. Residue remained. Used (initially) warm fingers
to melt and wipe off frost/water.
Changed propane and flashcard. Returned propane tanks
weighed 32# and 52#. 52# tank will not be refilled!

result later tonight.
PRESS: ok
TSOIL: ok Tsoil at Atlanta very stable compared to others. Explains near
constant and low heat flux noted below.
GSOIL: Gsoil at Cleveland seems to have recovered from possible footprint near
or on it. Recent storm probably blew in fresh snow cover. Atlanta
Gsoil, though, looks nearly flat compared to other 3 sites.
SONICS: As noted above, thoroughly cleaned all frost off sonic heads at
Cleveland. Good data for all of an hour before they started riming

A "shutdown" of the shebop pc caused the logbook entries for 11/15/97-11/24/97
to be lost from the logbook. Entries for 11/15-11/20 were recovered from an
email copy and re-stored in the logbook as entry #124. Entries for 11/21-11/24
are not recoverable, but contained little besides routine comments. The one
exception is that on 11/22, Florida's propane tank was changed.
Coincidentally, it had run out of propane one hour earlier, having used up
its propane at a rate slightly higher than before. (Or possibly the zero on
the scale had been bumped and the propane weight was wrong.) The TEG was
still warm and started right up.

FYI -> before I did the mods ~1300 Alaskan I found pampoll in the suspend mode. I had to hit the reboot/power button twice. I held it for one sec then release. The first time it cleared the suspend icon ( still locked up, though ), then once more to reboot it.

- 530: RF_Communications, Site base, Sun 14-Jun-1998 19:09:53 AKDT, Base Antenna
Last week I asked the ship's tech to check out the base antenna after we had
lost the data link during the rain. He didn't find anything wrong then, but
yesterday he was up on the mast and checked the N connector between the ship's
heliax and the NCAR antenna cable. The connector was full of water. He dried
and taped it back up. This should help out on those rainy days.

- 724: Base_Software, Site base, Tue 01-Dec-1998 10:09:02 MST, Post field: merged packet data
The packet files from the "flash" and "polled" directories on
shebop were read from the backup tape that Tom/John made just
before shutdown. These files were merged with the ones
we had here on /net/pam, and the data copied into the netcdf
files.
Therefore, the netcdf files here at NCAR should be complete.
