Subject: | TWP/VCEIL/C2 - Time offset |
DataStreams: | twpvceil25kC2.b1 |
Description: | On 7/14/2006, I found that the ceilometer time was 8m 36s slow, the PC time display (lower right taskbar) was frozen at "22:24", and AboutTime was not running. Corrected it on 7/17 by running AboutTime so that 19:03:29 became 19:12:05. This also corrected the frozen display on the Windows98 taskbar. I am not sure of the start time of this problem but there were several other Windows related issues that had to be corrected on 5/14 with indications of inappropriate access via Remote Administrator on 5/13. I do not know if the time offset was a sudden or gradual change. |

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). |
