Subject: | TWP/GNDRAD/C2 - IRT signal |
DataStreams: | twpgndrad60sC2.b1 |
Description: | When the other GNDRAD radiometers were replaced on 12/3/2006, the quality of the IRT signal began to degrade until 12/26 when it became unusable. The instrument was replaced on 2/4/2007. |

Subject: | TWP/GNDRAD/C2 - Reprocess: IRT calibration |
DataStreams: | twpgndrad60sC2.b1 |
Description: | The configuration of the IRT was set to that used at TWP/C3. This caused the calibration of the data to be wrong. It was corrected by reconfiguring the IRT to match the datalogger program. These data can be reprocessed and corrected by adding 10K, i.e. sfc_ir_temp(new) = sfc_ir_temp(old) + 10K. |
