Subject: | TWP/SMET/C1 - Upper wind speed sensor failure |
DataStreams: | twpsmet60sC1.b1 |
Description: | The upper wind speed sensor was binding at low wind speeds. Comparison to the lower wind sensor showed that the upper sensor flat-lines for long periods of time. The upper anemometer was replaced. |

Subject: | TWP/SMET/C1 - Reprocess: Barometric Data Changed from hPa to kPa |
DataStreams: | twpsmet60sC1.b1 |
Description: | Barometric pressure data was converted from hPa to kPa in order to standardize the measurement units among ARM sites and to conform to accepted standard units determined by the scientific community. |

Subject: | TWP/SMET/C1 - Reprocess: Tipping bucket rain gauge added |
DataStreams: | twpsmet60sC1.b1 |
Description: | A tipping bucket rain gauge was added to the TWP.C1 SMET suite of instruments on 20061017. Effective 20060926, two new variables (count and rain amount) were added to the end of the twpsmet60sC1.b1 datastream. Between 9/26 and 10/17, the data for these two variables are filled with zeros. Users should not use the data during this period as the zeros are not representative of the rain fall at the site. When reprocessing of this datastream occurs these variables will be added for the 19961009-20060926 and data from 19961009-20061017 will be filled with -9999 (missing). |

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. |
