1.0  DATA SET OVERVIEW
     

This data set contains 10 minute resolution precipitable water vapor
along with vertical profiles of water vapor mixing ratio, relative 
humidity, linear depolarization ration, and aerosol scattering 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 13 May to 25 June 2002.  The data are in 
netCDF format.
