SGP/THWAPS/B5 - Reprocess: RH values 10% Above Actual
DataStreams:sgpthwapsB5.b1
Description:
The T/RH probe was replaced with a recently calibrated sensor.  The newly installed probe 
did not have the correct span 0-110% RH for output.  This caused the readings to 
artificially high by 10%.
Measurements:sgpthwapsB5.b1:
  • Standard Deviation of Relative Humidity(sd_rh)
  • Relative humidity inside the instrument enclosure(rh)

SGP/THWAPS/B1 - Wind Data Incorrect Due to Icing
DataStreams:sgpthwapsB1.b1
Description:
An ice storm caused the wind data from the RM Young wind sensor to be
incorrect.  In many instances it was frozen and unmoving, at times it
measured values but those are extremely suspect.
Measurements:sgpthwapsB1.b1:
  • Mean Wind Speed(wspd)
  • Standard Deviation of Wind Direction(sd_wdir)
  • Unit Vector Wind Direction(wdir)

SGP/THWAPS/B1 - T/RH Data Incorrect
DataStreams:sgpthwapsB1.b1
Description:
The T/RH data was incorrect during the listed time period.  Reason unknown.  The sensor 
recovered on it's own.
Measurements:sgpthwapsB1.b1:
  • Standard Deviation of Relative Humidity(sd_rh)
  • Vapor Pressure (kiloPascals)(vap_pres)
  • Standard Deviation of Air Temperature(sd_temp)
  • Beam 0 Temperature(temp)
  • Standard Deviation of Vapor Pressure(sd_vap_pres)
  • Relative humidity inside the instrument enclosure(rh)
