NSA/METTWR/C2 - Chilled Mirror grounding and timing issues
DataStreams:nsamettwr2hC2.b1
Description:
From beginning of data stream, the chilled mirror data was intermittent at best.  Problems 
with grounding and timing issues between logging instruments caused data to be incorrect 
and at times missing.
Measurements:nsamettwr2hC2.b1:
  • Chilled Mirror Temperature(CMHTemp)
  • Chilled Mirror Calculated Saturation Vapor Pressure(SatVPCMH)
  • Chilled Mirror Calculated Vapor Pressure(VPCMH)
  • Chilled Mirror Calculated Relative Humidity(CMHRH)
  • Chilled Mirror Dew Point(CMHDP)

Subject:
NSA/METTWR/C2 - Incorrect Maximum for Precip Values
DataStreams:nsamettwr2hC2.b1
Description:
The max values for cumulative rain sum of 99 mm and the rain rate of 999 mm/hr are 
incorrect.  In communication with the manufacturer it has been found that the manual was in 
error.  The actual max values of the cumulative rain sum is 99.99 mm and the rain rate is 
999.99 mm/hr.
Measurements:nsamettwr2hC2.b1:
  • Precipitation Rate(PCPRate)
  • Cumulative Water Sum(CumH2O)

NSA/METTWR/C2 - Reprocess: Barometric Data Changed from hPa to kPa
DataStreams:nsamettwr2hC2.b1
Description:
Barometric pressure data was converted from hPa to kPa in order to standardize the 
measurement units among ARM sites and to conform to accepted standard units determined by the 
scientific community.
Measurements:nsamettwr2hC2.b1:
  • Atmospheric Pressure(AtmPress)
