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.
Measurements:	sgpsirsE24.00: Raw data stream - documentation not supported(Raw data stream - documentation not supported) sgpsirs20sE24.a0: Instantaneous Downwelling Hemispheric Shortwave, Unshaded Pyranometer Thermopile Voltage(inst_global) sgpsirsE24.b1: Downwelling Shortwave Hemispheric Irradiance, Ventilated Pyrgeometer, Maxima(down_short_hemisp_max) Downwelling Shortwave Hemispheric Irradiance, Ventilated Pyrgeometer(down_short_hemisp) Downwelling Shortwave Hemispheric Irradiance, Ventilated Pyrgeometer, Minima(down_short_hemisp_min) Downwelling Shortwave Hemispheric Irradiance, Ventilated Pyrgeometer, Standard Deviation(down_short_hemisp_std)

Subject:	SGP/SIRS/E7 - Downwelling Shortwave incorrect
DataStreams:	sgpsirsE7.00, sgpsirsE7.b1
Description:	Downwelling shortwave values dropped off to unrealistic values frequently at this site (usually between 1600 GMT and 0000 GMT). SGP techs found this was due to a bad multiplexer and it was replaced 04/05/2005 1950GMT along with the downwelling shortwave cable.

Subject:	SGP/SIRS/E3 - Reprocessed: Longwave Calibration error
DataStreams:	sgpsirsE3.b1
Description:	Modified pyrgeometer calibration procedures were implemented beginning in March 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 August 2006.

Description:	Modified pyrgeometer calibration procedures were implemented beginning in July 2003. 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 August 2006.

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.
