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.
Measurements:sgpvceil25kC1.b1:
  • Aerosol volume backscattering coefficient at 355 nm(backscatter)
