SGP/THWAPS/B6 - Wind Speed Data Artificially Low
DataStreams:sgpthwapsB6.b1
Description:
The wind speed data is lower than surrounding sites during this time period.  Icing 
conditions were occurring leading to the lower wind speeds as the sensor was artificially 
slowed.
Measurements:sgpthwapsB6.b1:
  • Mean Wind Speed(wspd)

SGP/THWAPS/B5 - Wind Speed and Direction Data Incorrect
DataStreams:sgpthwapsB5.b1
Description:
Wind speed and direction data were incorrect as the sensor was frozen.
Measurements:sgpthwapsB5.b1:
  • Standard Deviation of Wind Direction(sd_wdir)
  • Mean Wind Speed(wspd)
  • Unit Vector Wind Direction(wdir)

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)
