Subject: | TWP/SMET/C2 - connection and timing issues with new logger |
DataStreams: | twpsmet60sC2.b1 |
Description: | Atmospheric pressure data are intermittent during this time period due to connection problems and program timing issues with new logger installation. Data resumed normal operations after this time period. |

Subject: | TWP/SMET/C2 - Incorrect rainrate equation used. |
DataStreams: | twpsmet60sC2.b1 |
Description: | There are two different Optical Raingages in use at the TWP sites. The incorrect equation was used at this site. The incorrect equation is (25*(V^1.87)) - 0.15. The correct equation is (20*(V^2)) - 0.05. The correct equation was installed. |

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). |
