Subject: | SGP/IRT/E19 - Reprocess: Calibration error |
DataStreams: | sgpirtE19.b1, sgpirt200msE19.a1 |
Description: | The IRT was measuring ~20K higher sky temperatures than at other nearby extended facilies. The calibration of the instrument was incorrect. The problem was corrected by replacing the IRT. The offset in the calibration will be determined and the data will be corrected. |

Subject: | SGP/IRT/E19 - Response time |
DataStreams: | sgpirtE19.b1, sgpirt200msE19.a1 |
Description: | The time response of the temperature measurement was changed from 1.0 to 0.1 sec to accommodate the 5Hz sample rate. This caused a 370% decrease in the resolution (to 1.85C at a sky temperature of -50C) and a significant decrease in the signal-to-noise ratio. |
