Subject:	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.
