Subject:
SGP/VCEIL/C1 - poor signal
DataStreams:sgpvceil25kC1.b1
Description:
When parameters were changed (set noise_h2_compensation to "ON" and units to "METERS") to 
correct a low amplitude problem, the backscatter plots began displaying horizontal 
stripes indicating detector "ringing". However, the cloud base heights are not affected. The 
problem was corrected when the instrument was replaced.
Measurements:sgpvceil25kC1.b1:
  • Detection status. See details(detection_status)
  • Aerosol backscatter coefficient at 355 nm(backscatter)
