Subject: | SGP/IRT/E15 - Instrument noise problem |
DataStreams: | sgpirt200msE15.a1, sgpirtE15.00, sgpirtE15.b1 |
Description: | The data was much noisier than other nearby sites (a factor of 4-5 times more). The connections and communication and other settings were checked. The IRT was replaced on 1/29/2008 at 17:37 but the response time was incorrectly set to 0.01 s. This problem was corrected when the setting was changed to 0.10 s. |

Subject: | SGP/IRT/E13 - Reprocess: Sky temperature bias |
DataStreams: | sgpirt200msE13.a1, sgpirtE13.b1 |
Description: | Measurements of sky temperature, especially those <250K,, were positively biased compared with AERI because there was no compensation for the effect of the emissivity and temperature of the gold mirror. The problem was corrected by changing the IRT emissivity from 1.000 to 0.987, adding an RTD and transmitter electronics to measure the temperature of the mirror, and changing the ambient temperature measurement for internal reference to external mirror temperature. Use sky temperature measurements less than 230K with caution. Biases as large as 30K have been observed when the actual temperature, as measured by AERI, is less than 210 K. |

Subject: | SGP/IRT/E13 - Reprocess: wrong units |
DataStreams: | sgpirt200msE13.a1, sgpirtE13.b1 |
Description: | While diagnosing serial communication problems, the IRT configuration was reset to factory defaults so the temperature unit parameter was set to C instead of K. |
