SGP/MWR/B5 - Some rain events flagged
DataStreams:sgpmwrlosB5.b1, sgpmwrtipB5.a1
Description:
March 18 there was a strong rain event. During this time the brightness temperatures where 
> 100 K due to water accumulating on the radiometer, however the wet window flag 
indicator was not tripped.  Users should not rely on the wet window flag to screen 
rain-contaminated data.  Instead, apply a brightness temperature threshold of 100 K instead to both 
channels.
