The Atmospheric Radiation Measurement (ARM)
Program is a multi-laboratory, interagency
program that was created in 1989 with funding from
the U.S. Department of Energy (DOE). The ARM
Program is part of DOE's effort to resolve scientific
uncertainties about global climate change with a
specific focus on improving the performance of
general circulation models (GCMs) used for
climate research and prediction. These improved
models will help scientists better understand the
influences of human activities on the earth's climate.
In pursuit of its goal, the ARM Program establishes
and operates field research sites, called Cloud and
Radiation Testbeds (CARTs), in several climatically
significant locations. Scientists collect and analyze
data obtained over extended periods of time from
large arrays of instruments to study the effects and
interactions of sunlight, radiant energy, and clouds
on temperatures, weather, and climate.
