Subject: | NSA/MWR/C1 - Spikes in air temperature readings |
DataStreams: | nsamwrlosC1.b1, nsamwrtipC1.a1 |
Description: | During this month there are occasional negative spikes in the Tkair variable. The problem may be corrosion in the temperature sensor or the infiltration of water from melting snow. The dewblower was replaced and a new sensor installed |

Subject: | NSA/METTWR/C1 - 2m Datalogger Failed |
DataStreams: | nsamettwr4hC1.b1 |
Description: | The 2m temperature, wind speed, wind direction, and relative humidity were reporting the missing value (-9999). |

Subject: | NSA/METTWR/C1 - CMH required Calibration |
DataStreams: | nsamettwr4hC1.b1 |
Description: | The Chilled Mirror was showing some signs of being out of calibration. Temperatures were at times higher than co-located temp probes and the dew point temperature values at times were not consistent with co-located RH sensors. |

Subject: | NSA/METTWR/C1 - 2m level data incorrect |
DataStreams: | nsamettwr4hC1.b1 |
Description: | The 2m data for temp, RH, dew point, wind speed wind direction & vapor pressure were incorrect. The voltage values for the datalogger at that level were reporting as 60V with excursions to 100V. These values should have damaged the logger at that level. After an extended power outage on 08/04 the data all became reasonable. There is no explanation as to the cause of this failure. |

Subject: | NSA/MWR/C1 - Incorrect brightness temperatures and retrievals |
DataStreams: | nsa5mwravgC1.c1, nsamwrlosC1.b1, nsamwrtipC1.a1 |
Description: | The brightness temperatures and retrieved PWV and LWP show a sudden jump and have values that are too high. The suddenly jump back to normal at around 1800 UTC. All other parameters seem reasonable so the cause of the jump may just be due to accumulation of either snow or melting ice on the radome. |
