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/MWR/C1 - Incorrect brightness temperatures and retrievals |
DataStreams: | nsamwrlosC1.b1, nsamwrtipC1.a1, nsa5mwravgC1.c1 |
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, nsamwrtipC1.a1 |
Description: | The instrument was covered with a shield to test the effect on the RF interference that is affecting the measurements since February. The test was performed on 4/15 and 4/16 for a few hours. |

DataStreams: | nsamwrlosC1.b1, nsamwrtipC1.a1 |
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. |
