Subject: | SGP/MWR/E14 - Bias in 23.8-GHz measurements |
DataStreams: | sgpmwrlosE14.b1, sgpmwrtipE14.a1 |
Description: | Since the instrument was returned after a power supply failure the 23.8-GHz channel is constantly 3 K higher than the other co-located radiometer (C1). Since the instrument was just returned after extensive refurbishing at the manufacturer the cause of the bias is not clear. |

Subject: | SGP/VCEIL/C1/B4/B5/B6 - Reprocess: Incorrect serial_number and sum_backscatter fields |
DataStreams: | sgpvceil25kB4.b1, sgpvceil25kB5.b1, sgpvceil25kB6.b1, sgpvceil25kC1.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 collected prior to b1 level. |
