| Subject: | SGP/IRT/C1 - Degraded hardware |
| DataStreams: | sgpirt25mC1.b1 |
| Description: | The surface temperature from the 25m IRT was ~10K less than measured from the PIR. The lens was replaced on 2/8/2013 but there was still a bias. The problem was corrected when the IRT (and that at 10m) was upgraded to a newer model. It may be possible to determine the calibration offset, using the PIR as reference, and correct the surface temperature measurements. |
