Subject: | PYE/GNDRAD/M1 - Reprocessed: IRT configuration and calibration |
DataStreams: | pyegndrad20sM1.a0, pyegndrad60sM1.b1 |
Description: | The configuration of the IRT 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 IRT and changing the conversion factors in the data logger program. These data have been reprocessed to apply correct calibrations and the reprocessed data were archived 20070212. |

Subject: | PYE/GNDRAD/M1 - Reprocessed: 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 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 February 2007. |
