ARM review, 1991

The Department of Energy`s Atmospheric Radiation Measurement Program (ARM) is a major component of the US research program in global change. ARMs goals of quantifying the effect of clouds on the earth`s radiation budget is a key element in improving general circulation models (GCM) through enhancing understanding of the fast physics of the atmosphere. ARM is a well organized and managed program. A major concern for the programs future is the availability of adequate resources to establish and maintain observation sites in the Western tropical Pacific and on the north slope of Alaska.
