Subject: | TWP/SMET/C1 - C1 TWP Wind speed calibration factor problem/ Wind1 |
DataStreams: | twpsmet60sC1.a1, twpsmet60sC1.b1 |
Description: | Wind speed calibration factors were reversed between wind speed sensor 1 and 2. Results in less than 1% error, but correction factors may be used. |

DataStreams: | twpsmet60sC1.a1, twpsmet60sC1.b1 |
Description: | Wind speed calibration factors were reversed between wind speed sensors 1 and 2. Error results in less than a 1% error in wind speed. A correction factor may be used. |

Description: | (From Bill Clements) We have been using 6m MSL as the station elevation of Momote (Manus). This was based on information posted near the station barometer in the Momote Weather Service Office. It turns out that the official WMO station elevation for Momote is 4m MSL and the upper air elevation is 5m MSL. All Manus instruments except the sonde station are at 4m MSL. The sonde launching station is at 5m MSL. |

Subject: | TWP/SMET/C1 - Negative rainfall rates |
DataStreams: | twpsmet60sC1.b1 |
Description: | Due to limitations of the Zeno dataloggers all voltage measurements from the optical rain gauge (ORG) were converted to rainfall rates. This resulted in negative values for rain rates. Any value below 0.10 mm/hr should be considered to be 0 mm/hr. New dataloggers alleviated this problem. New loggers were installed 03/09/2004 @ 2243 GMT. |

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). |
