NSA/MWR/C2 - Frosting/Condensation

Doug reported freezing winds and ice accumulation on the MWR cover and radome. This may 
affect data quality and calibration. 
On 2/24 Doug attempted to slowly thaw the cover and clear the window.
From 2/22 to 2/24 the LWP and PWV reported by the MWR are near zero. These data are 
probably affected by the frost accumulated on the radiometer window.
