TWP/SMET/C3 - Intermittent Pressure Sensor Failure
DataStreams:twpsmet60sC3.a1, twpsmet60sC3.b1
Description:
The Barometric Pressure sensor was intermittently failing at TWP site C3 Darwin.  At times 
there were large pressure fluctuations occurring on the order of 24 mb in a few minutes. 
 Times of large pressure fluctuations are readily apparent in the data.  At these times 
the data should be carefully analyzed before determining it's usefulness.  In between the 
periods of large fluctuations the readings appear to be stable.  It is still suggested 
that independent pressure data be obtained for comparison before use.

TWP/SMET/C3 - Negative rainfall rates
DataStreams:twpsmet60sC3.b1
Description:
Due to limitations of the Zeno dataloggers all voltage measurements
from the optical rain gauge (ORG) were converted to rainfall rates. 
This resulted in negative values for rain rates.  Any value below
0.10 mm/hr should be considered to be 0 mm/hr.  New dataloggers 
alleviated this problem.

The wind_lower direction sensor failed on 4/14 and disagrees significantly with the

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)
