| Subject: | SGP/VCEIL/C1 - low amplitude |
| DataStreams: | sgpvceil25kC1.b1 |
| Description: | When the instrument was replaced with a spare, the backscatter plots began displaying a suspiciously low amount of amplitude (noise) but the cloud base heights were not affected. Discovered that when the vendor repaired this unit in August 2004, noise compensation was set to "OFF". Changed the parameters to "ON". Also noted that the measurement units was set to "FEET". This was changed to "METERS. The heights are not affected because the ingest recognizes the raw data units and automatically converts to meters. |

| 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. |
