SGP Extended Facility
For over 20 years, 23 extended facilities were distributed evenly throughout a 55,000-square-mile domain and at the corners of the Southern Great Plains (SGP) site. These instrumentation systems were intended to furnish datastreams to facilitate the spatial integration of the surface heat, moisture, and momentum fluxes across the SGP designated area.
Beginning in October 2009, the SGP site was redistributed into a smaller, denser footprint (150 km x 150 km) using the original instrumentation and making accommodations for new instrumentation added through the American Recovery and Reinvestment Act of 2009, resulting in 16 active extended facility sites. Extended facility instruments include an energy balance bowen ratio system (EBBR), eddy correlation (ECOR) surface flux station, surface energy balance systems (SEBS), broadband radiometers (SIRS, IRT), a multifilter rotating shadowband radiometer (MFRSR), and surface meteorological instrumentation (SMOS, RAIN).

*NOTE: Site designations are used in datastream naming conventions for the instruments located at these extended facilities. Each designation is only used once and assigned sequentially as each new extended facility opened. Gaps in numeric order may exist because planned sites were never opened.
