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.  It also contains the 915 MHz profiler data from 
the Atmospheric Boundary Layer Experiement (ABLE) project in the Walnut River 
watershed in Kansas. This data set covers the period from 20 May to 31 July 2003.
These data are in netCDF format.
