NSA/METTWR/C1 - CMH Dew Point and RH data Incorrect
DataStreams:nsamettwr4hC1.b1
Description:
The Chilled Mirror Dew Point reported negative dew point values.  This caused the RH to be 
much lower than reality also.  Compared to the 2m level the RH and dew point from the 
CMH are incorrect.  Mirror was dirty, it was removed, cleaned and recalibrated.
Suggestions: 
Measurements:nsamettwr4hC1.b1:
  • Chilled Mirror Dew Point(CMHDP)
  • Chilled Mirror Calculated Relative Humidity(CMHRH)
