TWP/SMET/C1 - Negative Rainfall Rates
DataStreams:twpsmet60sC1.a1
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.
Measurements:twpsmet60sC1.a1: 
  • Precipitation mean(precip_mean)
  • precipitation minimum(precip_min)
  • Precipitation maximum(precip_max)
  • Precipitation standard deviation(precip_sd)

TWP/SMET/C1 - Wind Speed data contain offset due to induced voltage
DataStreams:twpsmet60sC1.a1
Description:
The marine model of the RM Young wind sensor needs twisted pair shielded cable.  The 
manufacturer did not originally supply the pigtail with twisted pair shielded cable.  Use of 
twisted pair shielded cable for the rest of the cable run to the logger was also not 
specified.  This caused an induced voltage in the wind speed line from the wind direction 
excitation.  The induced voltage varied from sensor to sensor and probably changed anytime 
the cable was replaced or parts of the wind sensor were repaired or replaced. The induced 
voltage has been seen to vary from 0.15 m/s to as much as 1.08 m/s.
Measurements:twpsmet60sC1.a1: 
  • Wind #1 speed maximum gust(wind1_spd_max_gust)
  • Wind #2 speed minimum(wind2_spd_min)
  • Wind #2 speed arithmetic average(wind2_spd_arith_avg)
