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/ARSCL/C3 - Reprocess: ARSCL CloudBasePrecipitation field incorrect |
DataStreams: | twparscl1clothC3.c1, twparsclcbh1clothC3.c1, twpmmcrmode1bl200511041clothC3.c1, twpmmcrmode2ci200511041clothC3.c1, twpmmcrmode3ge200511041clothC3.c1, twpmmcrmode4pr200511041clothC3.c1 |
Description: | The CloudBasePrecipitation field is incorrect and has no physical meaning. An ARSCL processing error occurred when the smet60s data stream format changed, causing the wrong data field to be used to supply precipitation measurements to the ARSCL VAP. The error caused no significant degradation in other ARSCL fields, since manual quality control corrected any related errors. |

Subject: | TWP/MMCR/C3 - Reprocess: Height Error |
DataStreams: | twpmmcrmomC3.00, twpmmcrmomC3.b1, twpmmcrspecmomC3.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/ARSCL/C3 - Reprocess: MMCR Height offset affects ARSCL cloud boundaries |

Description: | MMCR heights were recorded as being too high 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 These errors may affect cloud boundaries that are determined by combining MMCR and MPL measurements; radar moments heights will be off by these amounts also. NOTE: reprocessing is underway. 20060101-20060228 have been reprocessed and archived. These data cover the period of TWP-ICE. |
