Subject: | NSA/MWRP/C1 - Incorrect calibration |
DataStreams: | nsamwrpC1.b1 |
Description: | On 4/12 a calibration was attempted but the calibration was not successful. A new calibration was completed on 4/13 20:00 UTC. Data between the two calibration attempts are incorrect and should be disregarded. |

DataStreams: | nsamwrpC1.00, nsamwrpC1.b1, nsamwrprawC1.00 |
Description: | After calibration was completed on 4/26/2006 the last value in the V-band calibration file was corrupted. V-band data are wrong between 4/26 19:30 and 4/27 15:27 when the corrupted values were removed. |

DataStreams: | nsamwrpC1.b1 |
Description: | After being re-installed the radiometer was calibrated with liquid nitrogen. Data between 8/8 and 9/6 have been reprocessed to apply the revised calibrations. |

Subject: | NSA/MWRP/C1 - Reprocessed: K-Band calibration drift |
DataStreams: | nsamwrpC1.b1 |
Description: | At the beginning of November, the K-band channel calibration started to drift. The MWRP brightness temperatures were about 1.5 K higher than the MWR-measured brightness temperatures. By the half of the month the differences were more than 2 K to become about 4 K by the end of November. On Nov 27 new calibration coefficients were derived and uploaded. Data for 20061101-20061127 have been reprocessed with the revised calibrations and are available from the ARM Archive effective January 2007. |

Subject: | NSA/MWRP/C1 - Reprocessed: 6-channel retrieval replaced by 5-channel retrieval |
DataStreams: | nsamwrpC1.b1 |
Description: | Due to repeated failure of the V-band receiver and calibration problems, the 6-channel retrieval was retired and a new 5-channel retrieval which uses only the K-band channels was implemented. All data previously processed with the 6-channel retrieval have been reprocessed. Please note that the 7 channels (brightness temperatures) in the V-band range (51 to 60 GHz) should not be used. See D080331.1 and D080331.2. |
