1.0  DATA SET OVERVIEW
     

This data set contains 8-minute vertical profiles of absolute temperature,
dew point temperature, and water vapor mixing ratio retrieved from the
Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Southern
Great Plains (SGP) Atmospheric Emitted Radiance Interferometer (AERI).  During
IHOP there were five AERI systems in operation on the ARM SGP site in
south central Kansas and north central Oklahoma.  This data set covers the 
period from 20 May to 31 July 2003.  These data are in netCDF format.
