Subject: | NSA/GVR/C1 - Instrument calibration |
DataStreams: | nsagvrC1.a0, nsagvrC1.b1 |
Description: | During the period of time specified, the instrument was undergoing calibration. The antenna pointed constantly to a hot load placed on the instrument window. All brightness temperatures during this time have temperatures > 300 K. |

Subject: | NSA/GVR/C1 - Temperature sensor wire broken |
DataStreams: | nsagvrC1.a0, nsagvrC1.b1 |
Description: | The temp_ext temperatures were occasionally spiking to very large values. Comparisons with the co-located 2m METTWR suggest the GVR exterior temperatures were not reporting correctly. Site ops found the temperature sensor had a broken wire and repaired it 7/13. |

Subject: | NSA/GVR/C1 - Incorrect auxiliary measurements |
DataStreams: | nsagvrC1.a0, nsagvrC1.b1 |
Description: | Between 6/16 and 6/19 there was a software problem and the auxiliary measurements all were reading constant values. The brightness temperature measurements do not appear to be affected. One of the incorrect measurements that may affect the use of the data is the surface temperature. This measurement should be disregarded. Measurements from a different instrument (such as the MWR) can be used to replace the GVR readings. |

Subject: | NSA/GVR/C1 - Incorrect ambient temperature readings |
DataStreams: | nsagvrC1.a0, nsagvrC1.b1 |
Description: | The ambient temperature readings are incorrect. The temperature sensor was replaced on 5/13, however the temperature readings were incorrect until 5/22 due to problems with corrosion in the cables |

Subject: | NSA/GVR/C1 - Saturated brightness temperature |
DataStreams: | nsagvrC1.a0, nsagvrC1.b1, nsagvrrawC1.00 |
Description: | Beginning 7/16 all sky temperature data become nearly equal and abnormally constant. The sky temperature data returned to normal on 7/22 ~20:00 UTC. The saturated brightness temperatures were probably due to water or dew deposit on the window. |

Subject: | NSA/GVR/C1 - Saturated brightness temperatures |
DataStreams: | nsagvrC1.a0, nsagvrC1.b1 |
Description: | Brightness temperatures are saturated probably because of water on the radome. Water vapor retrievals are affected as well. |
