SGP/SIRS/E12 - Ice obscured NIP

During the morning hours of 01/06, the direct normal shortwave readings are anomalously 
low in clear sky conditions, causing very large differences (approaching/exceeding 300 
W/m^2) between the downwelling shortwave hemispheric (DSH) readings and the derived 
downwelling shortwave hemispheric readings.  It would appear the NIP window had iced over during 
the previous days storm.  The NIP window appears to have cleared itself by the morning of 
2005/01/08.
