Group: Summary

   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 http://www.archive.arm.gov/armlogin/login.jsp.  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.
