| 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. |

| DataStreams: | sgpsirs20sE2.a0, sgpsirsE2.00, sgpsirsE2.b1 |
| Description: | The solar tracker was not working correctly at this site from 2/3/2005 to 2/5/2005 2359GMT. After this time tracker mounted instruments appear to have been responding correctly. There was no maintenance intervention that rectified the tracking problem. This has happened in the past with the SGP SciTec trackers. |

| Description: | During the DIR/UIR instrument changeout on 2/10/2005 the new datalogger program contained incorrect calibration coefficients for the DIR instrument. The program was corrected on 3/10/2005. These data were reprocessed and archived in September 2006. |

| Subject: | SGP/SIRS/E2 - Reprocessed: Longwave Calibration error |
| DataStreams: | sgpsirsE2.b1 |
| Description: | Modified pyrgeometer calibration procedures were implemented beginning in February 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 instanteous data records. Still, these data are considered far superior to the originally processed data. The reprocessed data were archived in September 2006. |
