Subject: | PYE/GNDRAD/M1 - Reprocess: wrong configuration and calibration |
DataStreams: | pyegndradM1.00, pyegndrad20sM1.a0, pyegndrad60sM1.b1 |
Description: | The configuration of the IRTs was inadvertently set to default and the program of the data loggers were changed to that used at TWP.C3. This caused the calibration of the data to be wrong. It was corrected by reconfiguring the IRTs and changing the conversion factors in the data logger program. These data can be either discarded, since they were collected prior to the "official" start of the PYE site, or reprocessed and corrected using the following translations: sfc_ir_temp(new) = sfc_ir_temp(old)*1.2 - 106.64K sfc_ir_temp_max(new) = sfc_ir_temp_max(old)*1.2 - 106.64K sfc_ir_temp_min(new) = sfc_ir_temp_min(old)*1.2 - 106.64K sfc_ir_temp_std(new) = sfc_ir_temp_std(old)*1.2 |

Subject: | PYE/GNDRAD/M1 - Reprocess: Longwave Calibration error |
DataStreams: | pyegndrad60sM1.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. |
