Subject: | TWP/SMET/C1/C2 - Switch to new Data Header Formats not timely |
DataStreams: | twpsmet60sC1.a1, twpsmet60sC1.b1, twpsmet60sC2.a1, twpsmet60sC2.b1 |
Description: | On April 1, 2001 at 00:00:00 new data header with consistent variable naming conventions, etc were to be used for all sites, all data streams. At the TWP sites the time of the movement to the new convention did not occur precisely at 00:00:00. The following data files contain between 40 seconds and 20 minutes of data from 4/1/02 in the old format. The delayed format change did not affect data quality in any way. twpsmet60sC1.a1.20010401.000001.cdf twpsmet60sC1.b1.20010401.000001.cdf twpsmet60sC2.a1.20010401.000000.cdf twpsmet60sC2.b1.20010401.000000.cdf |

Subject: | TWP/SMET/C2 - Negative rainfall rates |
DataStreams: | twpsmet60sC2.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/C2 - Reprocess: Barometric Data Changed from hPa to kPa |
DataStreams: | twpsmet60sC2.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/C2 - Reprocess: Tipping bucket rain gauge added |
DataStreams: | twpsmet60sC2.b1 |
Description: | A tipping bucket rain gauge was added to the TWP.C2 SMET suite of instruments on 20061129. Effective 20060926, two new variables (count and rain amount) were added to the end of the twpsmet60sC2.b1 datastream. Between 9/26 and 11/29, 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 19981021-20060926 and data from 19981021-20061129 will be filled with -9999 (missing). |
