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. |

Subject: | SGP/WACR/C1 - Reflectivity and Height Offsets |
DataStreams: | sgpwacrC1.b1, sgpwacrspeccmaskxpolC1.a0, sgpwacrspeccmaskcopolC1.a0 |
Description: | The instrument vendor has informed us of a range (height) offset of 13 m and has provided an updated reflectivity calibration. All values reported for 'Reflectivity' are approximately 3 dB too low. In addition, the Reflectivity in the first and fourth range gates (starting from the surface) need to be further corrected by an additional 2.7 and -0.9 dB, respectively. The 'height' field values are 13.33 m too low. The data will be reprocessed to correct these problems. Update: The sgpwacrC1.b1 data were reprocessed to correct the height and reflectivity offsets. The corrected data were archived 20100910-20100915. |
