Notes:  This is a brief description of the upper-air meteorological data
acquired by a radar wind profiler at the Raging Waters entertainment complex.
A Radian 915-MHz phased-array radar wind profiler was deployed in a dirt
parking lot.  Wind profiles were acquired as one-hour averages.  The data
acquisition computer time was set to Mountain Daylight Savings Time (MDT).
Wind profiles were acquired between 14:00 MDT on 04 October 2000 and 08:00 MDT
on 27 October 2000.

The original (raw) ASCII data files acquired by the radar are found in the CNS
directory.  The final naming convention is wyrjul.cns, where 'w' stands for wind
profile data, 'yr' is the two-digit year, and 'jul' is the Julian day.
For example, the first data file for VTMX is W96278.cns, where the year is 1996
and the Julian day of 278 is October 4.  It should be pointed out that the year
was set to 1996 on the data acquisition computer clock.  This was done to avoid
so-called Y2K computer glitches since the POP4.x software used to acquire these
data was not Y2K complient.

Files in the MOM directory contain binary moments data.  The final naming
convention is hyrjula.mom and dyrjula.mom.  In this case 'h' and 'd' represent
header and data files, respectively, and 'a' represents the first moments data 
file of that day.  Common data format (CDF) files were generated using
'lapcdf.exe'. This routine, found in the PROGRAMS subdirectory, ingests the raw
CNS data files and generates ASCII data files found in the 'CDF_A'
subdirectory.  The final naming convention is rag6mmdd.w1a and rag6mmdd.w2a,
where 'rag' is the three-letter abbreviation for the Raging Waters site, '6' is
the last numerical digit of the year (i.e., 1996), 'mm' is the month, 'dd' is
the day, 'w' represents wind profile, '1' and '2' represents the radar
operational mode (1 for 60-m wind resolution and 2 for 100-m resolution), and
'a' is the first version of the CDF data file.  These CDF data files were run
through a quality control screening algorithm (lapqc.exe) found in the PROGRAMS
subdirectory. This program, based on the Weber-Wuertz algorithms, objectively
removes questionable data such as spikes and outliers.  These data files are
found in the CDF_B subdiretory and use the naming convention of rag6mmdd.w1b
and rag6mmdd.w2b, where 'b' represents the second version of these CDF data.

Data files found in the CDF_CMDT subdirectory are the final version of these
CDF files and have the naming convention of rag0mmdd.w1c and rag0mmdd.w2c,
where '0' represents the year 2000, and 'c' represents the third version. Data
in this directory are identical to those found in CDF_B with the exception of
being corrected for the proper year.  Data converted to UTC time can be found
in the CDF_CUTC subdirectory. Wind profile in CDF_CMDT and CDF_CUTC may be
displayed and printed with 'lapg.exe' found in the PROGRAMS subdirectory.

JPG images of profiles on the major tracer IOPs are found in the
CDF_CMDT\IMAGES subdirectory. In addition, two sets of six Surfer (Golden
Software, version 6.03) files are included.  These contour plots represent
climatological averages of the data availability, scalar wind speed, vector
wind speed, eastward (U) wind speed, northward (V) wind speed, and persistence
(ratio of the vector wind speed to the scalar wind speed).
