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.
