VORTEX-95 WSI NIDS Single Radar Data
     
     
     1.0  General Description
     
          The VORTEX-95 WSI NIDS Single Radar Dataset contains several
     WSR-88D Level III products that were archived from the WSI NIDS
     datastream during the Verification of the Origins of Rotating
     Tornados Experiment (VORTEX-95).  This experiment was conducted
     in the area 31 - 40 North Latitude and 91 - 107 West Longitude
     during the time period April 1 - June 15, 1995.
     
     2.0  Detailed Data Description
     
          This dataset contains base reflectivity and velocity at 0.5
      and 1.5 degrees, composite reflectitivity, and Vertical Azimuth 
     Display (VAD) wind profiles from 13 sites.  The sites are listed below.

     2.2  Data Remarks

          This dataset is contained on one exabyte tape per week.  This tape
     contains one UNIX tar file for each UTC day on the tape.  

           The structure inside of each tar file is the same.  Each tar file
     contains one directory per station (see abbreviations above).  Each station
     directory contains on subdirectory per product. These directories are
     named as follows:

                BREF1			Base Reflectivity at 0.5 degree
                BREF2			Base Reflectivity at 1.5 degrees
                VEL1			Velocity at 0.5 degree
                VEL2			Velocity at 1.5 degrees
                CREF			Composite Reflectivity
		STAT			Radar status messages
		VAD			Vertical Azimuth Display

     Within each directory, the filename for each file is composed as
     follows:

			YYYYMMDD_hhmm_PPPPP.SSS

     Where:

		YYYY is the year of observation
		MM is the month of observation
		hh is the hour of observation
		mm is the minute of observation
		PPPPP is the product abbreviation
		SSS is the  station id (without K).


     Each individual file is in WSI NIDS format.
     
     
     3.0  Quality Control Processing
     
          No additional quality control was performed on
     the data by the UCAR/OFPS.  There are some gaps in the
     data due to loss of the real-time data feed.
