Subject:
SGP/TSI/C1 - Heater problem
DataStreams:sgptsiskyimageC1.a1, sgptsiskycoverC1.b1, sgptsicldmaskC1.a1
Description:
The TSI was converted from a model 880 to 660 which requires separate power for the mirror 
heater. The heater was not powered during this period so morning dew and other 
condensation was not quickly evaporated.
Suggestions: 
The sky image may appear "hazy" and the cloud fraction may be incorrect when the 

relative humidity, measured by SMOS, is near 100%.
