1.0  DATA SET OVERVIEW
     

This data set contains 60 second resolution surface infrared temperature
from 10 and 25 m downward looking pyrometer.  In addition the 25 m data
includes upwelling longwave and shortwave hemispheric irradiances.
Both the 10 and 25 m IRT sensors are located at the ARM SGP Central Facility.
This data set covers the period from 13 May to 25 June 2002.  The data are 
in netCDF format.
