Subject:
SGP/SIRS/E9 - PSP dome contamination
DataStreams:sgpsirs20sE9.a0, sgpsirsE9.b1, sgpsirsE9.00
Description:
Measured values of diffuse shortwave downwelling radiation fluctuated below derived values 
of downwelling shortwave radiation by 50 W/m^2 during the afternoon hours under clear 
conditions. 

SMOS precipitation and wind speed data reveals rain and wind the night before on 02/20/03 
0100 GMT probably contaminated the PSP dome with dirt.

Precipitation of .25mm on 02/23/04 0300 seems to have effectively cleared the PSP dome 
since PSP data on 02/24/04 compares correctly to direct and diffuse components.
