Abstract. The current version of the Dutch Atmospheric Large-Eddy Simulation (DALES) model is presented. DALES is a large-eddy simulation model designed for process studies of the atmospheric boundary layer, including convective and stable boundary layers as well as cloudy boundary layers. In addition, DALES can be used for studies of more specific cases, such as flow over sloping or heterogeneous terrain, and dispersion of inert and chemically active species. This paper contains an extensive description of the physical and numerical formulation of the code, and gives an overview of its applications and accomplishments in recent years.
