BAROMETER: 
 
	The channel_config file was changed for 
ragwort serial channel 202, ie, barometer. The 
communication parameters were changed to 1200,7,7. 
Ragwort data collection was turned off then on at 
about 00:10 GMT.

Reservoir bottles are mostly frozen still 
 
Steve and I just opened up the 1 and 2m units to check - only about 
3 mm of water is not frozen around the side of the main reservoir bottle. 
We'll just wait for them to thaw.

Pretty good agreement between the wet and dry temps, though.

1m wet bulb appears too warm. 
Need to keep an eye on it if it 
ever thaws again.

7m WET BULB is DRY: 
 
	The 7m wet bulb appears to have gone 
dry. Tomorrow we will change the wicks.

7m TWET is DRY: 
 
	The 7m twet bulb has been dry all day. 
It will be taken caare of tomorrow. 
 
181: PSYCS , Site none, Mon 04-Mar-1991 12:27:39 MST, PSYC TOWER WORK:
PSYC TOWER WORK: 
 
	The psyc. tower was lowered to work 
on the psychrometers. Their wicks were changed  
and bottles filled. This took place from about 
17:30 to 19:10 GMT. 
 
	We will let it run for awhile to see 
if everything looks good. 
 
NOTE: the 10m unit's fan was not housed properly. 
This must of been in this state for some time because 
it's bottle still had water in it. 
 
 
182: PSYCS , Site none, Mon 04-Mar-1991 13:49:21 MST, PSYC CONDITIONS:
PSYC CONDITIONS: 
 
	The 4m wet bulb is reading too high and 
the 7m dry bulb looks low compared to the 10m psyc. 
We will let it run over night and hope for the best. 
 
193: PSYCS , Site none, Tue 05-Mar-1991 18:28:27 MST, Dropped psychrometer tower at 22:30
Dropped psychrometer tower at 22:30 
to work on 4m wet bulb and 7m dry 
bulb.  Tower back up at 23:30. 
 
Steve found that the 7m dry bulb  
extended below the shield that separates 
the wet and dry bulb and that the dry 
bulb was getting wet.  The wick on the 
4m wet bulb was too short. 
 
 
206: PSYCS , Site none, Wed 06-Mar-1991 14:30:10 MST, Psycrometer errors
Psycrometer errors 
The 7m psyc tdry is colder than the 10m tdry throughout 
most of the day/night. Possibly a moisture problem. 
 
 
 
 
220: PSYCS , Site none, Fri 08-Mar-1991 12:36:36 MST, TDRY.7m:
TDRY.7m: 
 
	The tdry sensor at 7m is reading lower 
then the 10m sensor. The question is which one is 
at fault. Since we had problems with the 7m unit 
before it is the likely choose. However, after watching 
xstrip for awhile, it appears that the 10m sensor is not 
responding the same as the 7m and 4m. We will try to lower 
the tower today to do some servicing on it. 
 
update: As discovered before, the fan may be our problem 
at 10m. It may have slipped out again.

After fixing and filling bottles the tower 
was backup at 22:10 GMT. Tower came down
