Subject:	SGP/SIRS/E27 - Instrument problem, Shadowband Misalignment
DataStreams:	sgpsirsE27.00, sgpsirsE27.b1, sgpsirs20sE27.a0
Description:	Downwelling and Upwelling longwave values are somewhat noisy due to noisy PIR (pygeometer) case and dome thermistor measurements on both the upwelling and downwelling PIRs. This problem dates back to the beginning of the SIRS E27 data stream.

Subject:	SGP/SIRS/E27 - Tracker Misalignment
DataStreams:	sgpsirsE27.00, sgpsirsE27.b1, sgpsirs20sE27.a0
Description:	Suntracker failed at this facility. The suntracker was reset on 9/17, but this only temporarily fixed the problem and the tracker began failing again 9/18. Tracker was reset and realigned on 10/15/03 17:30GMT and has been operating properly since.

Subject:	SGP/SIRS/E27 - incorrect tracking
DataStreams:	sgpsirsE27.00, sgpsirsE27.b1, sgpsirs20sE27.a0
Description:	The solar tracker at E27 was not functioning properly. The problem affected tracker mounted instruments: downwelling diffuse 8-48 and direct normal pyrheliometer NIP. After tracker adjustment on 4/14/2004 1700GMT the tracker stopped tracking properly during afternoon hours. Attempts to correct tracker operation throughout the failure period resulted in variations on incorrect tracker operation. No replacement tracker was available. After adjustment on 9/15/2004 the tracker problem was resolved. It is unclear what, other than typical az and zen tracker software changes by field techs, corrected the problem. This problem period corresponds to the first time range specified (4/14 to 9/15). On 10/27/2004 a replacement tracker was installed at E27. Technical difficulties kept tracker out of service until 11/05/2004. The replacement tracker at E27 was put into serice by the field techs on 11/05/2004 1830GMT. The tracker has been tracking correctly since this time. This problem period corresponds to the second time range (10/27 to 11/05).

DataStreams:	sgpsirsE24.a2, sgpsirsE24.b1, sgpsirs20sE24.a0, sgpsirs60sE24.a1
Description:	The NIP is shaded by the EF laptop computer enclosure near sunrise during parts of the Spring and Summer. This has occurred from 04/08 to 05/20 and from 07/26 to 09/06 every year since 2001 and will occur during these date ranges in the future as well. The shading occurs for a few minutes each day between 1200 and 1300 GMT depending on the time of the year. For the early dates, shading occurs a little after 1200 GMT and by 05/20 shading happens nearer to 1300 GMT. In late July the shading occurs near 1300 GMT and closer to 1200 GMT by 09/06.

Subject:	SGP/SIRS/E24 - NIP shaded near sunrise
DataStreams:	sgpsirsE24.b1, sgpsirs20sE24.a0
Description:	The NIP is shaded by the EF laptop computer enclosure near sunrise during parts of the Spring and Summer.

Subject:	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.

Subject:	SGP/SIRS/E24 - Dirt on dome
DataStreams:	sgpsirsE24.00, sgpsirsE24.b1, sgpsirs20sE24.a0
Description:	The Downwelling Shortwave Hemispheric (DSH) Irradiance data were erratic. The Pyranometer instrument dome at this site was likely dirty given the relatively large spread between the measured DSH and derived DSH readings during the middle part of the day (up to 50 W/m^2). Rain on 04/06 most likely contributed to this problem. Preventative maintenance on 4/14 effectively cleaned the pyranometer dome. Preventative maintenance reports indicate dry-water spots on dome when it was cleaned on 4/14.

Subject:	SGP/SIRS/E24 - Reprocess: Incorrect calibration coefficients
DataStreams:	sgpsirsE24.00, sgpsirsE24.b1, sgpsirs20sE24.a0
Description:	Calibration coefficient for the downwelling diffuse measurement (8-48 B&W Eppley instrument) was incorrect after the instrument replacement 8/18/2005. Affected downwelling diffuse irradiance data can be corrected: Irr(corr) = Irr(uncorr) / 122.85 * 112.85 (or a overall multiplier of .9186)

DataStreams:	sgpsirsE24.00, sgpsirsE24.b1, sgpsirs20sE24.a0
Description:	During the PIR coefficient change from 4/coeffs to 1/coeff, the downwelling diffuse hemispheric instrument (Eppley 8-48) coefficient was inadvertently changed to 122.85 and should have been 112.85 W/m2/mV. Perform the following calculation to correct the data, DD=downwelling diffuse instrument: DD(new)[W/m2]=( DD(old)[W/m2]/122.85[W/m2\mV] )* 112.85[W/m2/mV]

Subject:	SGP/SIRS/E24 - Reprocessed: Longwave Calibration error
DataStreams:	sgpsirsE24.b1
Description:	Modified pyrgeometer calibration procedures were implemented beginning in July 2004. These modified procedures introduced a calibration bias in the longwave data. The previous procedures were re-implemented at all sites between December 2005 and February 2006 to restore proper calibrations. The data collected while the incorrect procedures were in place have been reprocessed to remove the calibration bias. The reprocessed 60 second averaged data are based on 3 instantaneous 20 second data records rather than on 60 1 second instantaneous data records. Still, these data are considered far superior to the originally processed data. The reprocessed data were archived in October 2006.
