ARM91

The Atmospheric Radiation Measurement (ARM) program is an initiative by the U.S. Department of Energy to study the effects of clouds on global climate change. Early effor for this program is focused on establishing several Clouds and Radiation Testbed (CART) sites which will make detailed measurements of four-dimensional fields of physical parameters over a 100 km by 100 km area. A four-dimensional data-assimilation model probably will be used to interpolate over the available measurements to obtain evenly-gridded fields.
