21: sonic, Site stn8_cosmos, Thu 27-Jul-2000 19:11:48 PDT, sonic to 20Hz
Since everyone else is running at 20 sps, I just changed the UW at stn8 to
do the same.  I'll have to decide if I want to do this elsewhere.

28: soil, Site stn8_cosmos, Sat 29-Jul-2000 09:30:42 PDT, site 8 boom angles
Since part of the intercomparison ends today, I shot boom angles this morning
for site 8 using the datascope, set for 15.0deg E declination, thus these should
be true.  I estimate the error as +/-0.2 deg.

UW 4.7	182.0
KD 1.7	173.3
KD 4.7	170.0
CSID 4.7	182.6
CSIHK 4.7	182.5
CSICH 4.7	133.9
GillHS 4.7	110.7
Prop1.7		182.9
Prop2.7		181.9
Prop4.7		181.1
Prop6.7		181.0
Prop8.7		181.9
Prop10.7	181.1

61: radiation, Site stn8_cosmos, Sun 06-Aug-2000 19:00:29 PDT, Psp.out removed
The Psp.out has been giving bad readings.
It appears to be a connection or the Eppley photopile
is bad.
62: temp_rh, Site stn8_cosmos, Sun 06-Aug-2000 19:01:34 PDT, Tsfc*4 added, sort-of
I installed the 4 tsfc infrared temp. sensors as follows:
tsfc1 at 10cm above ref. pointing south
tsfc2 at about 40 cm. pointing 30-deg out from base to north
tsfc3 at 50cm above ref. pointing north
tsfc4 at 50cm above ref. pointing south
Ref = top height of ridges.

However....
the CR10 logger is reporting all -39.00 for these values.
There appears to be a programming or wiring error based
upon where the connections are vs. the comment in the
program listing.  Unfortunately this is a CR10, not 10x
so it needs to have a prom written to retain any changes
in the program.
More later...

Note: I need to verify the 30-degree angle and the level
of the other sensors.  2 of them do not have the adjusting
knobs and tsfc3 is loose and pointing a little above horizontal.
64: radiation, Site stn8_cosmos, Mon 07-Aug-2000 15:19:49 PDT, TSFC at central site (8) working
The TSFC probes at station 8 are working now.
The wrong calibration factors were used.

65: soil, Site stn8_cosmos, Mon 07-Aug-2000 16:21:34 PDT, Soil mositure at site 8 working
The soil moisture at station 8 is ok now. Another
programming error! The wrong channel was being
selected.



66: radiation, Site stn8_cosmos, Mon 07-Aug-2000 16:47:49 PDT, Rsw.out at site 8 working
The Rsw.out sensor is working now.
It was another case of bad wiring inside the ventillation plenum.

94: other, Site stn8_cosmos, Sun 13-Aug-2000 17:25:52 PDT, Intercomparison towers removed from field
The 2 pam masts and the rohn tower were removed from
the field this afternoon.


110: props, Site stn8_cosmos, Wed 16-Aug-2000 11:38:31 PDT, wind directions
I've plotted wind direction as a function of time of day for the top prop
for Tom to use in SGS.  At night, it is about 290 degrees, during the day
about 340 degrees, with some days a shift to 030 degrees in the afternoon.
The 1.7m prop data are similar, though with more scatter.

111: props, Site stn8_cosmos, Wed 16-Aug-2000 15:45:59 PDT, direction of 1.7m prop reset
Steve S just used the alignment tool and I reset the boom alignment here about
2 min ago.  An edited version of the rserial session is appended below.  
Note the change of direction from 710 to 0, which will have to be included
in the cal_file.  Also note that this unit (#3) was supposed to have been
set up correctly in the lab, and may have a collar slippage problem.
The problem started on Aug 11 at ~19:00 local.

121: sonic, Site stn8_cosmos, Sun 20-Aug-2000 10:55:26 PDT, UW setup at station 8
The broken UW was setup at station 8 ata height of 1.7m
on the UW tower. This sonic is questionable and data should
be used with caution! Time was ~10:40 local.
  The sonic has 1 bad transducer along the A axis.



134: props, Site stn8_cosmos, Thu 24-Aug-2000 12:06:02 PDT, profiles dropped
Both the T/RH and Prop profiles were torn down over the last 2 hours.
In the process, the breezecom antenna was moved, which stopped ingest
for cosmos.  I've just revived this by mxreset, but we lost 2 hours of
data.  

This is the first stage of tear-down.  By now, most of the Swiss instruments
are down, and the Dutch pulled stuff off yesterday.  The profile at s7
also is being removed.
