1.0  DATA SET OVERVIEW
     

This data set contains 10 minute resolution depolarization ratio
from the Department of Energy (DOE) Atmospheric Radiation Measurement 
(ARM) Southern Great Plains (SGP) Raman Lidar (RL).  The RL is
located at the ARM Central Facility near Lamont, Oklahoma.  This data 
set covers the period from 20 May to 07 July 2003.  The data are in 
netCDF format.
