Subject: | NSA/MWR/C1 - Instrument problem, Heater problem |
DataStreams: | nsamwrlosC1.b1 |
Description: | The heater of the MWR was ON all the time even when the moisture sensor was dry. Jim Liljegren suspected a problem with the relay that activates the heater. The suggested action was to send the faulty assembly to SGP for repair and get a spare unit from SGP. The spare unit was sent on 9/15 and was installed on 10/18. |

Subject: | NSA/MWR/C1 - New software version (4.15) installed |
DataStreams: | nsamwrlosC1.b1 |
Description: | A problem began with the installation of MWR.EXE version 4.12 in September 2002. The software had been upgraded from a "DOS" to a "Windows"-compiled program to address an earlier problem. The software upgrade corrected the earlier problem but introduced a new one that caused line-of-sight observing cycles to be skipped, a 15% reduction in the number of tip curves, and saturation of CPU usage. Software versions 4.13 and 4.14 also produced these problems. The new MWR software version (4.15) was installed on 9/15/2005. As a consequence of this upgrade, the tip curve frequency increased. The tip cycle time decreased from ~60s to ~50s. |

Subject: | NSA/MWR/C1 - Reprocessed and Corrected:wrong calibration |
DataStreams: | nsamwrlosC1.b1 |
Description: | DATA REPROCESSED and CORRECTED: The calibration had changed as a result of the repairs made by Radiometrics and the RF deck temperature had been set to 325K for testing. The temperature was decreased to 307K to prevent thermal instability in winter and the calibration was changed in the configuration file with the values supplied on the repair report. The calibration coefficients were derived automatically after the changes were put into affect. The data were reprocessed using the derived calibration coefficients. ORIGINAL DQR CATEGORY: Red( Incorrect) REPROCESSED and CORRECTED DATA ARCHIVED:2016-03-29 REPROCESS IDENTIFICATION NUMBER: RID 209 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- When MWR#20 was returned to service on 9/1/2005, the calibration had changed as a result of the repairs made by Radiometrics and the RF deck temperature had been set to 325K for testing. On 9/2, the temperature was decreased to 307K to prevent thermal instability in winter and the calibration was changed in the configuration file with the values supplied on the repair report. The data need to be reprocessed with the calibration coefficients that were automatically derived after these changes were put into affect. They are: tnd_nom23=185.621, tnd_nom31=158.801, tc23=-0.022, tc31=-0.039. |

Subject: | NSA/MWR/C1 - Incorrect time stamp |
DataStreams: | nsamwrlosC1.b1 |
Description: | On Sept 27 the motherboard of the MWR computer was replaced. Following the replacement, the date on the computer was not set to the correct time of day, therefore the date and time in the files were wrong. The time on the computer was reset on Sept. 30. Time stamps between Sept. 27 and Sept. 30 were later corrected based on gathered information, however they may have as much as 5 minutes of uncertainty. |

Subject: | NSA/MMCR/C1 - Sensitivity Loss, Calibration Wrong |
DataStreams: | nsammcrspecmomC1.a0 |
Description: | Jay Mace compared data from CLOUDSAT to the MMCR and found significant discrepancies. It appears that the MMCR has a sensitivity problem and is underreporting reflectivity by ~20 dBZ. A comparison with the MPL shows that this might be a gradual degradation, i.e. there are no apparent shifts identifying when this might have occured. |
