1.0  DATA SET OVERVIEW
     

This data set contains hourly vertical profiles horizontal wind speed and wind
direction retrieved from the Department of Energy (DOE) Atmospheric Radiation 
Measurement (ARM) Southern Great Plains (SGP) 915 MHz Radar Wind Profilers.  The
915 MHz profilers were operated at the ARM SGP Central Facility and the three
ARM SGP Intermediate Facilities.  This data set covers the period from 13 May to 
25 June 2002.  These data are in netCDF format.
