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.
Measurements:sgpmwrtipE14.a1:
  • tbskytip23
  • vaptip
sgpmwrlosE14.b1:
  • 23.8 GHz sky brightness temperature(tbsky23)
  • Total water vapor along LOS path(vap)

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.
