Subject: | TWP/SMET/C3 - Instrument logger problem, Sensor failure |
DataStreams: | twpsmet60sC3.b1 |
Description: | The wind_lower direction sensor failed on 4/14 and disagrees significantly with the wind_upper direction. The wind_lower sensor reports a constant value around 0-15 degrees since it failed. Testing showed that excitation channel two on the logger was the problem. Logger was replaced by spare. |

Subject: | TWP/SMET/C3 - Reprocess: Barometric Data Changed from hPa to kPa |
DataStreams: | twpsmet60sC3.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/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. |
