Remote sensing strategy at the first Atmospheric Radiation Measurement field site

The Atmospheric Radiation Measurement (ARM) Program was initiated in 1990 by the US Department of Energy to improve climate model simulations of radiative energy transport and cloud formation, maintenance, and dissipation. ARM stresses the modeling of phenomena occurring at subgrid scales in general circulation models (GCMs). Measurements to support the modeling research will be made at three primary locations. The central facility, the primary location at the Southern Great Plains (SGP) site for study of radiative transfer, uses ground-based remote sensing instrumentation to observe radiation and the atmospheric properties that affect it. Remote sensing instruments and balloon-borne sounding systems installed at several boundary facilities on the perimeter of the overall Cloud and Radiation Testbed (CART) site evaluate vertical profiles of wind, temperature, and humidity. These observations are needed to run single-column models derived from GCMs for a single grid square with an area equivalent to the overall CART area. Observations of local meteorological conditions, air-surface exchange, and solar and infrared radiation at up to 23 extended facilities scattered throughout the CART site provide the surface boundary information needed in the single-column models. Finally, auxiliary facilities at the central facility and at a few locations within 10 km of the central facility will contain whole-sky imaging systems to map cloud characteristics. The purpose of this presentation is to describe the strategy used to obtain remote sensing instrumentation for continuous operation at the central facility.
