NSA/MET/C1 - CMH failure
DataStreams:nsametC1.b1
Description:
Starting 14:17 GMT on 12/4/2011 the CMH Dew Point began reporting missing value, CMH 
relative humidity was flat-lining at 100% and CMH saturated vapor pressure was flat-lined at a 
high value.  This condition continued very intermittently for several months.  Issue was 
frosting and a failed ventilation fan.
