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. |

Subject: | SGP/SIRS/E18 - Reprocess: Longwave Calibration error |
DataStreams: | sgpsirsE18.b1 |
Description: | Modified pyrgeometer calibration procedures were implemented beginning in December 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 are being reprocessing to remove the calibration bias. Note, this also affected standard deviation, maximum and minimum data fields. |
