Subject:
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)

Subject:
TWP/SMET/C2 - Reprocess: Barometric Data Changed from hPa to kPa
DataStreams:twpsmet60sC2.b1
Description:
Barometric pressure data was converted from hPa to kPa in order to standardize the 
measurement units among ARM sites and to conform to accepted standard units determined by the 
scientific community.
Measurements:twpsmet60sC2.b1:
  • Atmospheric pressure(atmos_pressure)
