Subject:
SGP/SASZE/C1 - Occasional signal saturation
DataStreams:sgpsaszevisC1.a1, sgpsaszefilterbandsC1.a1
Description:
During summer months around noon when the sun is near zenith the SASZe is susceptible to 
saturation when viewing brightly illuminated clouds. The saturation is mild and is limited 
to relatively few pixels around 500 nm and 600 nm where sunlight is most intense and 
does not appear to bleed into adjacent pixels. The visible effect in the data is radiance 
values that appear to level off to a fixed high value and that don't reflect the natural 
variation of nearby pixels.
Suggestions: 
It is not recommended to use saturated data values, but because the saturation is 

mild it is reasonable to merely screen out affected pixels for a given time rather than 
discard the entire measured radiance spectra.
