TWP/SMET/C2 - connection and timing issues with new logger
DataStreams:twpsmet60sC2.b1
Description:
Atmospheric pressure data are intermittent during this time period due to connection 
problems and program timing issues with new logger installation.  Data resumed normal 
operations after this time period.
Measurements:twpsmet60sC2.b1:
  • Atmospheric pressure(atmos_pressure)

TWP/SMET/C2 - Negative rainfall rates
DataStreams:twpsmet60sC2.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.
Measurements:twpsmet60sC2.b1:
  • Precipitation maximum(precip_max)
  • Precipitation mean(precip_mean)
  • precipitation minimum(precip_min)
  • Precipitation standard deviation(precip_sd)

TWP/SMET/C2 - Incorrect rainrate equation used.
DataStreams:twpsmet60sC2.b1
Description:
There are two different Optical Raingages in use at the TWP sites.  The incorrect equation 
was used at this site.  The incorrect equation is (25*(V^1.87)) - 0.15.
The correct equation is (20*(V^2)) - 0.05.  The correct equation was installed.
