Subject: | TWP/MMCR/C3 - Possibly corrupt netcdf file |
DataStreams: | twpmmcrspecmomC3.a0 |
Description: | The file twpmmcrspecmomC3.a0.20060331.020000.cdf was potentially corrupted during storage at the archive. The file successfully responds to an "ncdump" command and the data look reasonable. However, the file is only half the volume expected. There are no backups for these data so we are unable to attempt a recovery. |

Subject: | TWP/MMCR/C3 - Diminished Reflectivity Sensitivity |
DataStreams: | twpmmcrmomC3.b1, twpmmcrspecmomC3.a0 |
Description: | Radar sensitivity was diminished by approximately 15 - 20 dBZ during this period. The result is that upper level cloud tops may be missed and thin clouds, particularly thin cirrus, may not be detected during this period. Reflectivity was correctly calibrated, so values are correct where signals were detected. The problem was caused by lightning damage to the low noise amplifier (LNA). The LNA was replaced on 20060718. |

Subject: | TWP/MMCR/C1 - Reprocess: Height Error |
DataStreams: | twpmmcrmomC1.00, twpmmcrmomC1.b1, twpmmcrspecmomC1.a0 |
Description: | A timing error was found in the PIRAQ MMCR's. It resulted in recorded heights being too high for each radar mode by the following amounts: Mode 1: 24.8756 m too high Mode 2: 25.6249 m too high Mode 3: 33.1176 m too high Mode 4: 33.1176 m too high Range gate spacing was not affected. |

Subject: | TWP/MMCR/C1 - Error in recorded heights |
DataStreams: | twpmmcrmomC1.00, twpmmcrmomC1.b1, twpmmcrspecmomC1.a0 |
Description: | An error in MMCR configuration resulted in a timing error. This caused erroneous height values (too large) to be recorded in the data files. |
