Subject: | SGP/IRT/C1 - Reprocess: Some min and max values swapped |
DataStreams: | sgpirtC1.b1 |
Description: | During the time period specified the minimum and maximum sky_ir_temp values for the first record of each hour are swapped with the minimum being reported as sky_ir_temp_max and the maximum being reported as sky_ir_temp_min. |

Subject: | SGP/IRT/C1 - Reprocess: Longwave Calibration error |
DataStreams: | sgpirt25mC1.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. |

Subject: | SGP/IRT/C1 - UPS failing |
DataStreams: | sgpirt10mC1.b1 |
Description: | The IRT data were intermittently bad during this period due to a failing UPS. The problem was corrected by replacing the UPS. |
