The Atmospheric Radiation Measurement Program: Prelude

Atmospheric Radiation Measurement Program (ARM) - Summer 1995 Review

Study of Aerosol/Cloud/Radiation Interactions Over the Atmospheric Radiation Measurement Program Southern Great Plain Site

While considerable advances in the understanding of atmospheric processes and feedbacks in the climate system have led to a better representation of these mechanisms in general circulation models, the greatest uncertainty in predictability of future climate arises from clouds and their interactions with radiation. To explore this uncertainty, the cloud resolving model has evolved as one of the ...

Signal Postprocessing and Reflectivity Calibration of the Atmospheric Radiation Measurement Program 915-MHz Wind Profilers

The Department of Energy Atmospheric Radiation Measurement (ARM) Program has recently initiated a new research avenue toward a better characterization of the transition from cloud to precipitation. Dualwavelength techniques applied to millimeter-wavelength radars and a Rayleigh reference have a great potential for rain-rate retrievals directly from dual-wavelength ratio measurements. In this co...

The Atmospheric radiation measurement (ARM) program network of microwave radiometers: instrumentation, data, and retri vals

The Climate Research Facility of the US Department of Energy’s Atmospheric Radiation Measurement (ARM) Program operates a network of ground-based microwave radiometers. Data and retrievals from these instruments have been available to the scientific community for almost 20 yr. In the past five years the network has expanded to include a total of 22 microwave radiometers deployed in various loca...

Parameterizing the Dependence of Surface Albedo on Solar Zenith Angle Using Atmospheric Radiation Measurement Program Observations

This study evaluates the parameterization of the dependence of surface albedo on solar zenith angle (SZA) over snow-free land surface used by the National Centers for Environmental Prediction Global Forecast Systems (GFS) and those derived from the moderate resolution imaging spectroradiometer satellite observations as described in two recent studies. The influence of cloud cover on surface alb...
