Subject:
SGP/SIRS/E15 - PSP dome contamination
DataStreams:sgpsirsE15.b1, sgpsirs20sE15.a0
Description:
PSP dome was dirty.  Afternoon values of downwelling shortwave radiation were less than 
derived values by about 50 W/m^2.  

PSP values compare well to derived PSP values after precip event on 02/29/04 1300-1600 
GMT. Maintenance on 03/02 1713 GMT revealed no unusual contamination.  Precip on 02/29 
likely effectively cleaned the PSP dome.
Suggestions: 
Disregard afternoon PSP data from 1900-2300 GMT for clear skies
