NSA/METTWR/C1 - All data from 10m Level Missing
DataStreams:nsamettwr4hC1.b1
Description:
The winch that lowers the tower booms failed.  Manual testing of the motor and winch 
allowed the booms to be lowered briefly and then raised back into position.  A heavy freezing 
rain/icing event added extra weight to the booms.  This extra weight was suspected as the 
cause as to why the 10m boom became disconnected.  After a new motor was installed and 
all booms were lowered and re-raised the 10m level came back on line.
Measurements:nsamettwr4hC1.b1:

NSA/METTWR/C1 - Missing CMH data
DataStreams:nsamettwr4hC1.b1
Description:
CMH data are missing.  Corrosion in the serial data line connections caused a loss of 
communication with the CMH.
Measurements:nsamettwr4hC1.b1:
  • Chilled Mirror Calculated Vapor Pressure(VPCMH)
  • Chilled Mirror Calculated Relative Humidity(CMHRH)
  • Chilled Mirror Dew Point(CMHDP)
  • Chilled Mirror Temperature(CMHTemp)
  • Chilled Mirror Calculated Saturation Vapor Pressure(SatVPCMH)

Subject:
NSA/METTWR/C1 - 10m level loss of power
DataStreams:nsamettwr4hC1.b1
Description:
The 10 meter instrument level lost power so all variables from this level are missing.
Measurements:nsamettwr4hC1.b1:
  • 10m Average Calculated Dew Point(DP10M_AVG)
  • 10m Average QLI Reference Temperature(RefT10m_AVG)
  • Standard Deviation of 10m Calculated Vapor Pressure(VP10M_STD)

NSA/METTWR/C1 - 2m T/RH probe aspirator fan failed
DataStreams:nsamettwr4hC1.b1
Description:
The aspirator fan for the 2m level T/RH probe failed.  This caused higher than normal 
readings for temp and RH and artificially smoothed the data.
Measurements:nsamettwr4hC1.b1:
  • 2m Average Calculated Vapor Pressure(VP2M_AVG)
  • Standard Deviation of 2m Calculated Dew Point(DP2M_STD)
  • Standard Deviation of 2m Relative Humidity(RH2M_STD)
  • 2m Average Relative Humidity(RH2M_AVG)
  • Standard Deviation of 2m Calculated Vapor Pressure(VP2M_STD)
  • 2m Average Temperature(T2M_AVG)
  • Standard Deviation of 2m Temperature(T2M_STD)
  • 2m Average Calculated Dew Point(DP2M_AVG)
