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 50 MHz Radar Wind Profiler at the
ARM SGP Central Facility near Lamont, Oklahoma.  This data set covers the period 
from 20 May to 31 July 2003.  These data are in netCDF format.
