Twelfth Atmospheric Radiation Measurement (ARM) Science Team Meeting
Data collected during the SHEBA (Surface Heat Budget of the Arctic Ocean) field experiment and at the Barrow ARM site are used to evaluate shortwave and longwave radiative transfer (RT) codes used in climate models and for remote sensing applications under Arctic conditions. This project is being carried out as part of the GEWEX Cloud System Study WG5 - Polar Clouds Radiation model intercomparison. Initialization and validation data is available on the web which numerous researchers have already made use of. Several characteristics of the Arctic environment make RT difficult. These include low sun angles, high surface albedo with large spectral variations, low temperatures and water contents (in win- ter), large temporal variations in aerosol optical depth caused by sporadic Arctic Haze events, and the common occurrence of low water paths in clouds. Broadband and spectral radiative fluxes observed at the surface and the TOA are used to evaluate the RT codes under a variety of Arctic conditions including
