Subject: | TWP/SMET/C3 - Reprocess: Tipping bucket rain gauge added |
DataStreams: | twpsmet60sC3.b1 |
Description: | A tipping bucket rain gauge was added to the SMET suite of instruments effective 20060926. Two new variables (count and rain amount) were added at the end of the twpsmet60sC1.b1 datastream. When reprocessing of this datastream occurs these variables will be added with -9999 (missing) as the value for dates prior to gauge installation. |

Subject: | TWP/VCEIL/C3 - standard instrument installed |
DataStreams: | twpvceil25kC3.b1 |
Description: | A spare ceilometer without the tropics window option was installed. The manufacturer recommends the tropics window be used at +/- 25 deg lattitude to prevent direct solar radiation into the laser optics when the instrument pointed at zenith. No significant signal degradation is apparent during the autumnal equinox but, as a precaution, the unit was replaced with the original with a tropics window. |

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. |
