Entry ID



The Atmospheric Radiation Measurement (ARM) Program's primary objective is to test and improve General Circulation Model (GCM) parameterizations of clouds and their effect on the radiative energy balance. The ARM Program focuses on six research areas: 1) aerosols, 2) clouds, 3) longwave radiation, 4) shortwave radiation, 5) surface energy exchange (or flux), and 6) atmospheric state. Meteorology data from the North Slope of Alaska/Adjacent Arctic Ocean Cloud and Radiation Testbed (CART) site at Barrow, Alaska include wind speed, wind direction, air temperature, humidity, barometric pressure, visibility, and precipitation for the atmospheric column above the site. Radiation measurements at the site include longwave and shortwave radiation, including infrared and solar radiation. Solar radiation data include total daily solar radiation, direct-beam normal irradiance, downwelling hemispheric diffuse irradiance, and downwelling hemispheric irradiance. Infrared radiation data include radiance spectra ensemble (1800-3020 cm-1 and 520-1800 cm-1), mean radiances for short- and longwave wavenumbers, downwelling hemispheric infrared irradiance, longwave scene radiance spectral averages (AERI Ch1), longwave scene variability spectral averages (AERI Ch1), and net radiation.

Data are available at The ARM measurements are aggregated together in data files. A data file usually contains a time series of one or more measurements for a known time interval and a single location. Most data are stored in netCDF format. Some data files also contain one or more measurements distributed over a region from a single time (e.g., satellite images); these data are stored in HDF format.
