- 144: EVE, Site 2, Wed 22-Oct-2003 08:58:38 EDT, st2: sdr installed, eve problem
10/21/03 14:40-15:00
SDR Data: Inserted new CF and verified that it was working OK.
EVE problem: on 10/21 at 0Z the RAMDISK DIR. STRUCT. FAILED!
This was shown evidenced on syslog.log and on console
screen in 'failure to access'.
At that point any 'dir' or 'dir /card' failed,
DAQ fortunately was running, including sdr output (when good media!).
'REBOOT' RECOVERED full ops and the directory structure was
actually OK.
Thoughts:
Second/third time this has been seen: systems getting older
which is a problem, however:
1) EVE code must be examined closely for this problem (ie interrupt
contention on disk access, etc.) and auto recovery procedures.
2) DCOM332 boards must be fully exercized and tested, possibly checked
by manuf. as well. Using 'in-house' software, temp, etc.
- 143: Status, Site 2, Wed 22-Oct-2003 08:46:29 EDT, st2: FastData Outage
SDR Fast Data Outage From 10/14 to 10/20:
The upload of the 'sdr fastdata' compact flash recovered on
10/20 failed. After several checks, including back on a 'sdr'
we found: The MEDIA Itself FAILED !!!
Sandisk 06/03-3 had been used extensively during pre-proj tests
however this indicates 2 things:
1) During project: While servicing and esp. when inserting
a blank media, make sure data is being written successfully
by watching file sizes grow. (problem appeared in dir part.)
I didn't do that on st2 on 10/14 and the Tern dutifully created
file and happily chugged away even though the CF itself wasn't
recording.
2) After project: Perform CF life cycle testing to better
anticipate replacement schedule.

10/20/03 12:20-12:55
kh2o cleaned: everything was wet from dew, output went from .3mv to ~660mV
Soil sample taken
RG: ok but the bucket was essentially full from the last rain event,
which means it'll tip early next time.
SDR/metppf uploaded: NOTE: it appears the sdr data files were corrupt
and this needs to be checked on-site. Data loss from 10/15-20.

- 122: Site_visit, Site 2, Wed 15-Oct-2003 09:35:31 EDT, st2: CO2 Noise, Cal-table, Antenna moved
10/14/03 15:40-16:30, and 16:55-17:25
CO2/O3,etc Noise Problem: (see also entry 118)
The occurance of 5 min noise spikes in the AD data for this station indicated
GOES RF interference.
The Yagi antenna was relocated from the SE leg of the PAM tripod to the W leg
and then aligned to the original azimuth and tilt pointing.
CO2 Cal Tables:
The CO2 sensor data had been showing steps as the calibration switched between
different calibratin tables when the temperature hovers around 10-degC.
SteveO thought it would be useful to change the temp. threshold value to
keep the unit from switching tables:
>st stop unit
>tr0 29500 3080 0 0 0.7479 original values
>tr1 23000 2830 1 1 0.9035
>tr2 15300 2630 2 2 1.0590
Per SO changed tr0 from 3080 (ie 308degK) to 3280 and restarted.
Later returned per SO to change tr1 which he thought more appropriate.
That was put to 3030 (ie 303degK) however when doing that the unit would
not 'go' again, apparently due to inability to hit this temp. on the chiller.
Final Result: Returned tr0 and tr1 to original values so it'll work!
- 118: Site_visit, Site 2, Mon 13-Oct-2003 17:16:12 EDT, St2: Swap SOAD 'plate' (had noise during 'goes')
10/13/03 15:20-16:10 local
Purpose was to investigate Data glitch on AD during Xmit.
Suspected that the SOAD had the 'single-ended' jumper still on the
board but that was not the case.
'Serializer/AD' plates swapped 5 times between 15:20 and 15:30, while watching
data on PC.
At 15:45 spare replacement plate installed and fast data accumulated
for 20 minutes before being downloaded for exam back at base.
NOTE: at one point we observed microbaro voltage reported at 180mV but with
spare plate installed it was reporting at 1180mV....This could have
been due to the ad cable being plugged in slightly incorrectly when
we were using the original 'plate'.
NOTE: We did observe the 1180mV jump up by 5mV during xmit, however, this
is far less than what was seen in the fastout data (I think).....
wrong!...a check of the 'caled' data back at the base shows
that the step is still there. It equals about .1mB but is
very clear in the data.
NOTE: The CO2 pump audibly changes during xmit, indicating reduced airflow
perhaps and that could account for the increased 5mV signal ....maybe?
We should check where the pump is plugged in and
maybe try an 'independent' battery for it.
NOTE: The noise is also on O3, Vbatt, Tbatt but not Tsfc.
This implies location adjacent to the antenna is the culprit.
St2 has a yaggi located on the SE leg, immediately in line with
the microbaro, O3, etc. Cable shielding is the other possibility
and I don't know if SUNY put the shield on or not.

Arrived 1300 EDT; rain now heavy at times, but some clearing.
Walked the path from the road (really muddy, but found a Leatherman!)
Hoped to replace net dome, but one screw head stripped, so had to replace
entire sensor. Old: 91096; New: 94196 (had replaced dome since pulled from
s6)
Disconnected old; carried back to van; brought new to site; entered new coef;
mounted new; connected new. Thus, there shouldn't be any non-zero data with
bad coefs.
Grabbed SDR.
