Subject:	NSA/AERI/C1 - AERI infiltrated by packed snow
DataStreams:	nsaaerich1C1.b1, nsaaeriengineerC1.b1, nsaaerich2C1.b1, nsaaerisummaryC1.b1
Description:	A strong storm with blowing and drifting snow occurred March 9th and 10th during which time the hatch remained open and snow entered the front end of the AERI enclosure. During the period, the snow obscured scene mirror views of downwelling radiance as well as views into the Black Body cavities which provide reference radiances used for calibration. Snow also collected around components inside the enclosure thereby possibly interfering with scene mirror views after the storm until the snow was removed and the front end compartment was dried late on March 13th. Possible corrupting effects apply to all measurement data streams. Measurements are probably bad during the period of the storm and suspect following the storm through March 13th.
