Subject: | NSA/MWR/C1 - TKAIR sensor failure |
DataStreams: | nsamwrlosC1.b1 |
Description: | Between 7/14 and 7/28 the tkair variable is missing most of the time and sometimes has large negative spikes. On 7/28, the sensor was cleaned of corrosion and the readings came back to normal. |

Subject: | NSA/MWR/C1 - Rain sensor always on |
DataStreams: | nsamwrlosC1.b1 |
Description: | The rain sensor was always on between 10/5 and 10/23 2006. The user should be aware that not all data flagged as rainy are actually rainy. The problem was caused by a shift in the sensitivity of the rain sensor and was corrected by changing the sensor threshold in the configuration file. |

Subject: | NSA/MWR/C1 - Spikes in air temperature readings |
DataStreams: | nsamwrlosC1.b1 |
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/MWR/C1 - Incorrect brightness temperatures and retrievals |
DataStreams: | nsamwrlosC1.b1 |
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. |

DataStreams: | nsamwrlosC1.b1 |
Description: | Starting approximately on February 13 the MWR experienced high level of noise in the 23.8 GHz channel. The spikes became more prominent around Feb 17 and increased after that date as well. The cause of the interference was identified as the nearby MWRP on Oct 13 and the instruments were realigned. |
