SGP/SIRS/E11 - PSP dome contamination

Measured values of diffuse shortwave downwelling radiation fluctuated below derived values 
of downwelling shortwave radiation during the afternoon hours under clear conditions, 
probably due to a dirty PSP dome. 

SMOS precipitation and wind speed data reveal rain and wind on 02/19/03 at 2300 GMT 
probably contaminated the PSP dome with dirt.

Precipitation of .4mm on 02/29/04 1400 seems to have effectively cleared the PSP dome 
since PSP data on 03/01/04 compares correctly to direct and diffuse components.
