Subject: | SGP/IRT/C1 - Measurement range |
DataStreams: | sgpirt10mC1.b1, sgpirt25mC1.b1 |
Description: | The ground surface temperature exceeded the maximum measurement of 50C on some days. The maximum was increased to 60C for IRT10m on 10/1/2012 at 15:25 and for IRT25m on 10/9/2012 at 21:45. |

Subject: | SGP/IRT/C1 - 25m IRT ground surface temperature |
DataStreams: | sgpirt25mC1.b1 |
Description: | The 10m IRT was measuring lower ground surface temperature than the 25m IRT. The 25m lens was cleaned on 12/24/2012 and replaced on 2/8/2013 but the difference in temperature appears to be due to the seasonal difference in surface cover - tall grass vesus bare soil. |

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 is still a bias. The problem was corrected when the IRT (and that at 10m) was upgraded to a newer model. |
