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/E1 - broken cable on DSDH (aka DD) measurment instrument - Eppley 8-48.
DataStreams:sgpsirsE1.00, sgpsirsE1.b1, sgpsirs20sE1.a0
Description:
Occasionally, the downwelling shortwave diffuse hemispheric (DSDH) readings spike to

spike well below the actual DSH readings.  Technicians repaired the DSDH instument (an 
Eppley 8-48) cable on 02/08/2005 2055GMT.  There have been no dropouts since that time.

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/E12 - Reprocess: Incorrect calibrations
DataStreams:sgpsirsE12.00, sgpsirsE12.b1, sgpsirs20sE12.a0
Description:
During site corrective maintenance to resolve an Extended Facility data collection 
problem, the SIRS.E12 datalogger was power cycled (1725 GMT).  The datalogger reverted to an old 
SIRS program with incorrect S/Ns and calibration coefficients for all instruments at 
this station.

The SW data can be recalibrated as follows:
First divide value by incorrectly applied cal coeff (first number) then multiply by 
correct cal coeff (second number)
  down_short_diffuse_hemisp     107.27	118.68
  up_short_hemisp	        113.19	127.95

  down_short_hemisp             118.46	102.11

The LW data were recalibrated and reprocessed as part of a larger LW calibration task.  
The reprocessed data were archived in October 2006.

SGP/SIRS/E13 - Reprocess: incorrect calibrations
DataStreams:sgpsirsE13.00, sgpsirsE13.b1, sgpsirs20sE13.a0
Description:
After a long data gap on 5/25/2005, presumably a power outage, the following datastreams 
were showing incorrect values as well as incorrect calibration coefficients in the 
datalogger program:
down_long_hemisp_shaded (downwelling PIR instrument)
up_long_hemisp (upwelling PIR instrument)
short_direct_normal (NIP instrument)

The SIRS.E13 datalogger was power cycled (6/2/2005 2200GMT) and the correct program loaded 
into the SIRS datalogger and storage module.

The data during this time range can be recalibrated as follows:
First divide value by incorrectly applied cal coeff (first number) then multiply by 
correct cal coeff (second number)
  short_direct_normal           120.28	124.58
  up_long_netir                 0.2386	0.2595
  down_long_netir               0.3052	0.2304

Description:
C1 experienced a sun tracker power faulure.  The tracker was reset by onsite personnel 
shortly after the power failed.  Only shaded and direct instruments were affected - i.e. the 
downwelling diffuse measurement from the 8-48 B&W pyranometer and the direct normal 
measurement from the NIP pyrheliometer.  The downwelling longwave PIR data was unaffected by 
this event.

SGP/SIRS/E1 - Intermittantly missing downwelling diffuse
DataStreams:sgpsirsE1.00, sgpsirsE1.b1, sgpsirs20sE1.a0
Description:
Starting on or about 10/26/2005 the downwelling diffuse hemispheric irradiance (Eppley 
8-48) instrument had intermittant missing values. Technicians found a loose wire on the 
instrument connector and repaired it on 4/4/2006. 

Use global shortwave hemispheric (PSP) component - normal incident component (CosZA*NIP) 
to calulate diffuse component.  Comparison of absolute difference between actual and 
computed diffuse component values and diffuse standard deviations > 1-2 W/m2 can help filter 
the noisy diffuse data.  There is no standard method.
