ABSTRACT

The absence of solar radiation and the extreme cold temperatures during the Alaskan winters combined with ice- and snow-covered surfaces sets up outstanding meteorological conditions leading to the formation of layered temperature inversions. This layered structure has a large impact on the atmospheric boundary layer state controlling surface energy balance and surface turbulent fluxes. A synthesis of prominent features of the radiative boundary layer will be discussed. And, in the framework of IGAC-ALPACA, a closure experiment for radiative boundary layers will be described. The application of experimental datasets to developing new model parameterization will be shared with the community.
