SGP/SIRS/E10 - tracker failure
DataStreams:sgpsirsE10.00, sgpsirsE10.b1, sgpsirs20sE10.a0
Description:
During the night of 11/05-06 2004 the tracker failed at this location. During CM on 12/01, 
power cycling returned the tracker to service. However, tracker was not properly 
tracking in the AM. Tracker failed again sometime near 01/01/2005.  CM on reloaded the tracker 
program and realigned the tracker on 01/26/2005 1600GMT.  It has been working correctly 
since this time.

SGP/SIRS/E12 - Ice obscured NIP
DataStreams:sgpsirsE12.00, sgpsirsE12.b1, sgpsirs20sE12.a0
Description:
During the morning hours of 01/06, the direct normal shortwave readings are anomalously 
low in clear sky conditions, causing very large differences (approaching/exceeding 300 
W/m^2) between the downwelling shortwave hemispheric (DSH) readings and the derived 
downwelling shortwave hemispheric readings.  It would appear the NIP window had iced over during 
the previous days storm.  The NIP window appears to have cleared itself by the morning of 
2005/01/08.

SGP/SIRS/E15 - Failed NIP cable
DataStreams:sgpsirsE15.00, sgpsirsE15.b1, sgpsirs20sE15.a0
Description:
After the ice storm, the SHORT_DIRECT_NORMAL values were bad or
              missing continuously. Corrective Maintenance on 01/18 found
              the NIP cable had broken inside the Bendix connector. The NIP 
              cable was repaired and returned to service.

SGP/SIRS/E20 - Reprocess: Incorrect calibration coefficients
DataStreams:sgpsirsE20.00, sgpsirsE20.b1, sgpsirs20sE20.a0
Description:
Sometime during the day of 12/27/2004(first avialable day of data) or 12/24-12/26 (no 
archive data available) the SIRS datalogger at E20 was loaded with an old version of an E20 
program.  The calibration coefficients and serial numbers do not match those installed.  
Field techs installed a correct datalogger program on 1/19/2005 1900GMT.  However, 
sometime during 1/20/2005 the datalogger reverted to the wrong program again without user 
intervention.  On 2/16/2005 the correct SIRS program was reloaded on the E20 datalogger.

SGP/SIRS/E18 - Possible PSP dome contamination
DataStreams:sgpsirsE18.00, sgpsirsE18.b1, sgpsirs20sE18.a0
Description:
Downwelling shortwave hemispheric (DSH) measurements did not agree with derived DSH 
readings during the morning hours up to 1500GMT each clear day.   PM cleaning on 2/16 2250 
revealed nothing other than dirty water spots.  A dirty or ice covered PSP dome may have been 
the cause, clearing itself before the PM crew arrived.

SGP/SIRS/E13 - Monthly Report
DataStreams:sgpsirsE13.b1
Description:
:Data quality this site-month is good. The offset for the Global PSP is about -7 W/m^2.
The dominant problem here is the daytime 3 component problem. Direct and Diffuse are
always too high and Global is too low. The problem occurs around the time that the
testing regime switches from twilight to daytime testing regimes or from daytime to
twilight. The flags occur in significant numbers on the 1st - 5th, 7th - 20th, 24th - 
28th,
30th, and 31st. The failures vary in magnitude and duration. The worst flags for a 
particular

respect to this problem. Global goes below daytime empirical limits on both the 5th and
6th for substantial periods of time. Diffuse
also goes below daytime empirical limits on the 6th in the afternoon. Upwelling Longwave
is
below empirical limits on the 24th. This may not be a problem, as many sites exhibited
the same problem on the same night. Exceptionally cold temperatures may be the cause.

SGP/SIRS/E24 - Erratic downwelling shortwave data
DataStreams:sgpsirsE24.00, sgpsirsE24.b1, sgpsirs20sE24.a0
Description:
Downwelling shortwave hemispheric readings are occasionally erratic, jumping to very high 
or very low values for short periods of time. SGP PM techs reseated all Downwelling 
Shortwave PSP instrument connections on 3/17/2005 approx 1945GMT.  The problem did not reoccur 
after that time but the DS cable was replaced on 3/31/2005 approx 1815 GMT to ensure the 
problem did not reappear.
