The central facility, located near Lamont, in north-central Oklahoma, houses the core instrumentation for the Southern Great Plains (SGP) site and is the center of operations for SGP experiments. The facility houses a wide range of in situ and remote sensing instrumentation, including a millimeter-wavelength cloud radar, micropulse lidars, microwave radiometers, a ceilometer, several radar wind profilers, and the only continuously operated Raman lidar in existence.

The central facility’s state-of-the-art instrumentation is augmented by balloon-borne atmospheric profiling, surface radiation measurements and surface latent and sensible heat flux measurements. Because of its extensive collection of in-situ and ground-based remote sensing instruments, it is an ideal site for major collaborative field projects.
