TWP/C2/SMET Wind Speeds
DataStreams:twpsmetC2.00, twpsmet60sC2.a1, twpsmet60sC2.b1
Description:
Beginning on December 24, Anemometer #1 (there are two anemometers on
the SMET stand) occasionally reported wind speed values that were low
relative to the other sensor.  It is clear from the data that the low
reading here is the anomalous one.

Description:
On April 1, 2001 at 00:00:00 new data header with consistent variable naming
conventions, etc were to be used for all sites, all data streams.  At the TWP
sites the time of the movement to the new convention did not occur precisely at 00:00:00.  
The following data files contain between 40 seconds and 20 minutes of data from 4/1/02 
in the old format.  The delayed format change did not affect data quality in any way.

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)

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)

TWP/SMET/C2 - Reprocess: Tipping bucket rain gauge added
DataStreams:twpsmet60sC2.b1
Description:
A tipping bucket rain gauge was added to the TWP.C2 SMET suite of instruments on 20061129. 
Effective 20060926, two new variables (count and rain amount) were added to the end of 
the twpsmet60sC2.b1 datastream.  Between 9/26 and 11/29, 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 19981021-20060926 and data from 
19981021-20061129 will be filled with -9999 (missing).
Measurements:twpsmet60sC2.b1:
  • Time offset from base_time(base_time)
