Subject:
TWP/SMET/C1 - Upper wind speed sensor failure
DataStreams:twpsmet60sC1.b1
Description:
The upper wind speed sensor was binding at low wind speeds.  Comparison to the lower wind 
sensor showed that the upper sensor flat-lines for long periods of time.  The upper 
anemometer was replaced.
Measurements:twpsmet60sC1.b1:
  • Wind #1 speed standard deviation(wind1_spd_sd)
  • Wind #1 speed maximum gust(wind1_spd_max_gust)
  • Wind #1 direction standard deviation(wind1_dir_sd)
  • Wind #1 speed arithmetic average(wind1_spd_arith_avg)
  • Wind #1 speed maximum(wind1_spd_max)
  • Wind #1 direction vector average(wind1_dir_vec_avg)
  • Wind #1 speed vector average(wind1_spd_vec_avg)
  • Wind #1 speed minimum(wind1_spd_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:
  • Barometric Pressure(atmos_pressure)

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:
  • base time(base_time)

TWP/MMCR/C1 - Reprocess: Height Error
DataStreams:twpmmcrmomC1.00, twpmmcrmomC1.b1, twpmmcrspecmomC1.a0
Description:
A timing error was found in the PIRAQ MMCR's.  It resulted in recorded heights being too 
high for each radar mode by the following amounts: 
Mode 1: 24.8756 m too high
Mode 2: 25.6249 m too high
Mode 3: 33.1176 m too high
Mode 4: 33.1176 m too high
Range gate spacing was not affected.
Measurements:twpmmcrmomC1.b1:
  • Array of heights for each power(heights)

twpmmcrspecmomC1.a0:
  • Height of Center of Each Range Bin(Heights)

twpmmcrmomC1.00:
  • Raw data stream - documentation not supported(raw)

TWP/MMCR/C1 - Error in recorded heights
DataStreams:twpmmcrmomC1.00, twpmmcrmomC1.b1, twpmmcrspecmomC1.a0
Description:
An error in MMCR configuration resulted in a timing error.  This caused erroneous height 
values (too large) to be recorded in the data files.
Measurements:twpmmcrmomC1.b1:
  • Array of heights for each power(heights)

twpmmcrspecmomC1.a0:
  • Height of Center of Each Range Bin(Heights)

twpmmcrmomC1.00:
  • Raw data stream - documentation not supported(raw)
