Subject: | TWP/SMET/C3 - Intermittent Pressure Sensor Failure |
DataStreams: | twpsmet60sC3.a1, twpsmet60sC3.b1 |
Description: | The Barometric Pressure sensor was intermittently failing at TWP site C3 Darwin. At times there were large pressure fluctuations occurring on the order of 24 mb in a few minutes. Times of large pressure fluctuations are readily apparent in the data. At these times the data should be carefully analyzed before determining it's usefulness. In between the periods of large fluctuations the readings appear to be stable. It is still suggested that independent pressure data be obtained for comparison before use. |

Subject: | TWP/SMET/C3 - Data reported at 15sec rather than 60s intervals |
DataStreams: | twpsmet60sC3.a1, twpsmet60sC3.b1 |
Description: | Data in these data streams should be reports at 60sec intervals, but the logger program running during this time had the interval set to 15s. Users will have to average the 15sec data to get 60sec data. |

Subject: | TWP/SMET/C3 - Negative rainfall rates |
DataStreams: | twpsmet60sC3.a1 |
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. |
