TWP/SMET/C3 - Upper wind speed artificially slow
DataStreams:twpsmet60sC3.b1
Description:
The upper wind measurement was consistently slower by around 0.5 - 1 m/s than the lower 
wind measurement.  The bearings on the upper wind measurement were binding.
Measurements:twpsmet60sC3.b1:
  • Wind #1 speed minimum(wind1_spd_min)
  • Wind #1 speed maximum(wind1_spd_max)
  • Wind #1 speed standard deviation(wind1_spd_sd)
  • Wind #1 speed maximum gust(wind1_spd_max_gust)
  • Wind #1 speed vector average(wind1_spd_vec_avg)

TWP/SMET/C3 - ORG overestimated rainfall
DataStreams:twpsmet60sC3.b1
Description:
Optical rain gauge (ORG) measured approximately 10mm higher than two co-located tipping 
bucket rain gauges and a co-located disdrometer.  The ORG is typically higher but usually 
not by an order of magnitude.
Measurements:twpsmet60sC3.b1:
  • Precipitation mean(precip_mean)
  • Precipitation maximum(precip_max)
  • Precipitation standard deviation(precip_sd)
  • precipitation minimum(precip_min)

TWP/SMET/C3 - Upper Wind Sensor Data Questionable
DataStreams:twpsmet60sC3.b1
Description:
The wind_up vs. wind_low wind directions diverged, with the differences between the two 
eventually reached 45 degrees. The Upper sensor was found to be mis-aligned and loose.
Measurements:twpsmet60sC3.b1:
  • Wind #1 direction vector average(wind1_dir_vec_avg)
  • Wind #1 speed minimum(wind1_spd_min)
  • Wind #1 speed maximum(wind1_spd_max)
  • Wind #1 speed standard deviation(wind1_spd_sd)
  • Wind #1 speed maximum gust(wind1_spd_max_gust)
  • Wind #1 speed arithmetic average(wind1_spd_arith_avg)
  • Wind #1 speed vector average(wind1_spd_vec_avg)
  • Wind #1 direction standard deviation(wind1_dir_sd)

TWP/SMET/C1 - ORG Precip Data Incorrect
DataStreams:twpsmet60sC1.b1
Description:
Moisture intrusion into the sensor body allowed condensation on the lens of the ORG.  
Continual and long-term precipitation was reported during this time.
Measurements:twpsmet60sC1.b1:
  • Precipitation mean(precip_mean)
  • Precipitation maximum(precip_max)
  • Precipitation standard deviation(precip_sd)
  • precipitation minimum(precip_min)
