SGP/SIRS/E6 - Questionable data due to Ice Storm damage
DataStreams:sgpsirs20sE6.a0, sgpsirsE6.00, sgpsirsE6.b1
Description:
Several SIRS readings at E6 readings have appeared questionable since the ice storm in 
early January.  Starting on 01/13 maintenance found the E6 tracker inoperative. It was reset 
and put back into serivice.  Shortly after, on 01/16 data from the DSH instrument (PSP) 
became questionable possibly due to obstructed or failed ventilator fan.  On 02/10 1645 
GMT maintenance found the DSH instrument ventilator fan failed - the fan was replaced,  
the E6 tracker was also realigned.  Due to early january ice storms, the tracker alignment 
issues and a failed ventilator fan - All tracker mounted and global DS instrument 
measurements are suspect for this time frame.

SGP/SIRS/E6 - Reprocessed: Longwave Calibration error
DataStreams:sgpsirsE6.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 October 2006.

  • Upwelling (10 meter) Longwave Hemispheric Irradiance, Pyrgeometer(up_long_hemisp)
