Subject: | NSA/MWRP/C1 - Incorrect surface measurements |
DataStreams: | nsamwrpC1.b1 |
Description: | Surface measurements are spiking and not comparing well with co-located METTWR4h. On 1/13 site operators cleaned a filter in the heater housing. This solved the problem |

Subject: | NSA/MWRP/C1 - 6-channel LWP retrieval has large negative values |
DataStreams: | nsamwrpC1.b1 |
Description: | The 6-channel LWP retrieval had large negative values (<-0.05 mm) betweem 01/09 and 01/27, reaching minimum values of -0.1 mm around 1/17. The reason for the drift was a drift in the 51.25-GHz channel. Somehow, after 1/27 the values returned normal. |

Subject: | NSA/MWRP/C1 - Incorrect surface measurements |
DataStreams: | nsamwrpC1.b1 |
Description: | The MWRP surface temperature and pressure readings were in disagreement with those from other instruments. The possible cause of the disagreement was ice buildup around the sensors. Readings returned to normal March 29. The temperature readings were more affected. Since the readings are erratic, with large oscillations, it is not possible to correct them. Disregard the surface temperature and humidity readings during this time. The wrong readings will affect the first layer of the temperature and humidity profiles as well. |

Subject: | NSA/MWRP/C1 - Bias in 6-channel LWP retrieval |
DataStreams: | nsamwrpC1.b1 |
Description: | On 4/25 there was a slight shift in the calibration of the 51.25-GHz channel. This caused a bias in the 6-channel LWP retrieval that is now lower than the 2-channel retrieval |
