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. |
