| Subject: | SGP/VCEIL/B5 - Noisy Backscatter |
| DataStreams: | sgpvceil25kB5.b1 |
| Description: | Since October of 2004, the noise in the backscatter plots occasionally become high in amplitude for periods of time lasting anywhere from an hour or so to as much as a day. This problem appears similar to a dirty window (such as the problem at B6 last week), but the fact that the plots show high amplitude for short durations of time imply that this problem is different. Cloud base height detection appears to be unaffected. |

| 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. |
