Subject:
SGP/MPL/C1 - Reduced detection sensitivity
DataStreams:sgpmplsmask1clothC1.c1, sgpmplnor1campC1.c1, sgpmplC1.a1, sgpmplcmask1clothC1.c1
Description:
During the time periods indicated, the laser power supply was low.  This resulted in 
compromised detection sensitivity, particularly for thin clouds and/or during daylight hours.  
That is, some clouds may not have been identified.  The low laser power would not have 
resulted in false positives.
Suggestions: 
Some clouds may not have been detected.
