DOE ARM SGP SIRS Radiation Data
     
     
1.0  General Description
     

This data set contains 60 second resolution up/downwelling long/shortwave
hemispheric irradiances, and diffuse/direct shortwave irradiance from the
Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) 
Southern Great Plains (SGP) Solar Infrared Radiation Station (SIRS).  
These SIRS stations are located at many of the ARM SGP Extended Facilities
in southern Kansas and northern Oklahoma.  This data set covers the period
from 13 February 2002 through present.  The data are in netCDF format.
