1.0  DATA SET OVERVIEW
     

This data set contains hourly vertical profiles of virtual temperature and 
vertical wind velocity retrieved from the Department of Energy (DOE) 
Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) Radio
Acoustic Sounding System collocated with the 915 MHz Radar Wind Profilers 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.
