Subject: | NSA/SKYRAD/C1 - Shaded PIR data unreasonable |
DataStreams: | nsaskyrad60sC1.a1 |
Description: | There was a 10-25 W/m2 spike in data probably due to operator working around instrument or cleaning it. |

Subject: | NSA/SKYRAD/C1 - IRT measurements during precipitation events |
DataStreams: | nsaskyrad60sC1.a1 |
Description: | The IRT measurement of sky/cloud temperature was in question during precipitation events because rain or snow could accumulate in the upward-pointed lens barrel. This was corrected by reorienting the IRT to measure the sky temperature as reflected by a gold mirror. |

Subject: | NSA/SKYRAD/C1 - IRT insufficiently heated |
DataStreams: | nsaskyrad60sC1.a1 |
Description: | IRT had insufficient heating to maintain an internal reference temperature above 0 degrees C. Measurements of sky temperature were over-estimated when instrument was below freezing. |
