Subject: | TWP/SMET/C3 - Rain blocked pressure port |
DataStreams: | twpsmet60sC3.b1 |
Description: | Atmospheric pressure values were suspect due to anomolous readings during heavy rain events. Suspect blockage of port due to rainfall. New logger and enclosure corrected problem. |

Subject: | TWP/SMET/C3 - Data missing due to Logger Change |
DataStreams: | twpsmet60sC3.b1 |
Description: | All Data from this site are missing during this time period due to a change of the collection system, logger and enclosure. Data resumed after change. |

Subject: | TWP/SMET/C3 - Negative rainfall rates |
DataStreams: | twpsmet60sC3.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. |

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: Incorrect Units Listed for Vapor Pressure |
DataStreams: | twpsmet60sC3.b1 |
Description: | The netcdf file header incorrectly listed the units of Vapor Pressure as hPa when in fact they were kPa. |

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. |
