TWP/SMET/C3 - Rain blocked pressure port
DataStreams:twpsmet60sC3.b1
Description:
Atmospheric pressure values were suspect due to anomolous readings during heavy rain 
events.  Suspect blockage of port due to rainfall.  New logger and enclosure corrected problem.
Measurements:twpsmet60sC3.b1:
  • Atmospheric pressure(atmos_pressure)

Subject:
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.
Measurements:twpsmet60sC3.b1:
  • Precipitation mean(precip_mean)
  • Precipitation maximum(precip_max)
  • Precipitation standard deviation(precip_sd)
  • precipitation minimum(precip_min)

TWP/SMET/C3 - Reprocess: Barometric Data Changed from hPa to kPa
DataStreams:twpsmet60sC3.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:twpsmet60sC3.b1:
  • Atmospheric pressure(atmos_pressure)

TWP/SMET/C3 - Reprocess: Tipping bucket rain gauge added
DataStreams:twpsmet60sC3.b1
Description:
A tipping bucket rain gauge was added to the SMET suite of instruments effective 20060926. 
 Two new variables (count and rain amount) were added at the end of the twpsmet60sC1.b1 
datastream.  When reprocessing of this datastream occurs these variables will be added 
with -9999 (missing) as the value for dates prior to gauge installation.
Measurements:twpsmet60sC3.b1:
  • Time offset from base_time(base_time)
