SGP Intermediate Facility

For over 20 years, 3 intermediate facilities, within 6.2 miles (10 km) of the Central Facility, provided a three-dimensional mapping network of the atmosphere and of the cloud fields in the vicinity of the Central Facility. These original intermediate facilities included radar wind profilers, which specifically supported SGP investigations of radiative transfer in partly cloudy conditions; these facilities were retired in April of 2011.

With funding from the American Recovery and Reinvestment Act of 2009, the SGP site received an unprecedented suite of precipitation radars that are the cornerstones of the new intermediate facilities. Radar wind profilers from decommissioned sites are installed in new locations.
