Subject:
NSA/METTWR/C1 - 2m level data incorrect
DataStreams:nsamettwr4hC1.b1
Description:
The 2m data for temp, RH, dew point, wind speed wind direction & vapor pressure were 
incorrect.  The voltage values for the datalogger at that level were reporting as 60V with 
excursions to 100V.  These values should have damaged the logger at that level.  After an 
extended power outage on 08/04 the data all became reasonable. There is no explanation as 
to the cause of this failure.
Measurements:nsamettwr4hC1.b1:
  • Standard Deviation of 2m Vector Averaged Wind Direction(WD2M_SDU_WVT)
  • 2m Average Calculated Vapor Pressure(VP2M_AVG)
  • Standard Deviation of 2m Calculated Dew Point(DP2M_STD)
  • 2m Average Relative Humidity(RH2M_AVG)
  • Standard Deviation of 2m Relative Humidity(RH2M_STD)
  • 2m Average QLI Input Voltage(Volt2M_AVG)
  • 2m Vector Averaged Wind Speed(WS2M_U_WVT)
  • 2m Average Temperature(T2M_AVG)
  • Standard Deviation of 2m Calculated Vapor Pressure(VP2M_STD)
  • Standard Deviation of 2m Temperature(T2M_STD)
  • 2m Average QLI Reference Temperature(RefT2M_AVG)
  • 2m Average Calculated Dew Point(DP2M_AVG)
  • 2m Arithmetic Mean Wind Speed(WS2M_S_WVT)
  • 2m Vector Averaged Wind Direction(WD2M_DU_WVT)
