Subject: | GRW/MWR/M1 - Incorrect instrument computer set-up |
DataStreams: | grwmwrtipM1.a1, grwmwrlosM1.b1 |
Description: | Starting late on 07/11 the instrument began to have very brief (< 1 min) data outages every few hours. By 07/12 data had become noticeably incorrect, particularly the PWV, LWP, TB23, and TB31. At ~17 Z on 0713 the missing data / no data available flags became more frequent. The problem was identified as improper settings of the instrument computer and was solved on 8/9. |

Subject: | GRW/MWR/M1 - Erratic brightness temperature |
DataStreams: | grwmwrlosM1.b1, grwmwrtipM1.a1 |
Description: | Around 12 Z on 7/20 both the PWV and 23.8 GHz brightness temp values began to diverge from those of the MWRP. By 7/22 both the LWP and 31.4 GHz brightness temp had followed suit. At 0600 Z on 7/22 multiple (10-20), brief (<=1 min) data outages began appearing hourly. The problem persisted intermittently until 8/9. On 8/9, changes in the settings of the computer restored the proper functionality of the MWR software. |

Subject: | GRW/MWRP/M1 - Reprocessed: Updated calibration coefficients |
DataStreams: | grwmwrpM1.b1 |
Description: | On 9/8/2010 the calibration of of the K-band channels was updated. This caused a slight decrease of the retrieved liquid water path. Updated calibrations have been applied to data from 7/1-9/8. The LWP was decreased slightly as a result of the recalibration. Reprocessed data were archived in November 2010. |

Subject: | GRW/MWRP/M1 - Temp/RH sensor failure |
DataStreams: | grwmwrpM1.b1 |
Description: | The temperature and humidity sensor failed causing software crashes and poor retrieval quality. Surface temperature and humidity are incorrect and the bad temperature readings affected the retrievals. Users should completely disregard retrievals from this instrument. |

Subject: | GRW/MWRHF/M1 - Incorrect surface temp and RH |
DataStreams: | grwmwrhfM1.b1 |
Description: | The surface temperature and surface relative humidity did not compare well with the co-located MET system. The temperature was not too different than the MET system, but trended differently. The MWRHF RH values were often 20% or greater different and trended inversely. |
