Subject: | SGP/IRT/E13 - Reprocess: Sensor Calibration |
DataStreams: | sgpirt200msE13.a1, sgpirtE13.b1 |
Description: | The measurements are greater than AERI, especially when sky temperature is less than -40C. The lens and mirror was cleaned on 11/21/2008 and the mirror was replaced on 1/28/2009 but these actions did not correct the problem. It was learned that the internal calibration factor was not changed by the manufacturer after the unit was repaired and recalibrated on 9/6/2007. The calibration factor was corrected from 1.2172 to 1.4100 on 2/12/2009. |
