Subject:
TWP/SMET/C1 - Negative rainfall rates
DataStreams:twpsmet60sC1.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.  New loggers were installed 03/09/2004 @ 2243 GMT.
Measurements:twpsmet60sC1.b1:
  • Precipitation mean(precip_mean)
  • Precipitation maximum(precip_max)
  • Precipitation standard deviation(precip_sd)
  • precipitation minimum(precip_min)

TWP/SMET/C1 - Reprocess: Barometric Data Changed from hPa to kPa
DataStreams:twpsmet60sC1.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:twpsmet60sC1.b1:
  • Atmospheric pressure(atmos_pressure)

Subject:
TWP/SMET/C1 - Reprocess: Tipping bucket rain gauge added
DataStreams:twpsmet60sC1.b1
Description:
A tipping bucket rain gauge was added to the TWP.C1 SMET suite of instruments on 20061017. 
 Effective 20060926, two new variables (count and rain amount) were added to the end of 
the twpsmet60sC1.b1 datastream.  Between 9/26 and 10/17, the data for these two variables 
are filled with zeros.  Users should not use the data during this period as the zeros 
are not representative of the rain fall at the site.  When reprocessing of this datastream 
occurs these variables will be added for the 19961009-20060926 and data from 
19961009-20061017 will be filled with -9999 (missing).
Measurements:twpsmet60sC1.b1:
  • Time offset from base_time(base_time)
