| Subject: | TWP/VCEIL/C2 - Reprocess: Incorrect serial_number and sum_backscatter fields |
| DataStreams: | twpvceil25kC2.b1 |
| Description: | Attribute serial_number: In most cases, this field is not representative of the actual serial number of the instrument because the value did not change when an instrument changed locations or was replaced with a spare. Variable sum_backscatter: An out-of-range condition for the "sum of detected and normalized backscatter" was reported as 0 instead of missing (-9999). The valid range is 0 - 0.0999 /srad. This DQR also applies to a1 level data. |
