MAR (Regional Atmosphere Model)

MAR is an atmosphere model designed for meteorological and climatic research. It is used for a wide range of applications, from km-scale process studies to continental-scale multi-decadal simulations. It can be run for ideal test cases (e.g., 1-dimensional studies, simple gravity-wave configuration) or for realistic applications (constrained by reanalyses, operational forecasts, or global climate models). MAR was created in the mid-1990s, and most developments since then have been undertaken at IGE (former LGGE)/CNRS/UGA, Grenoble, France, and at the Liège University, Belgium. MAR is now open to the international community, and this website is designed to facilitate its implementation and use on various platforms and for a large range of applications.

MAR is well known for its fine representation of physical processes in polar regions. It is one of the few models able to simulate realistic surface mass balance, air-snow interactions, and atmospheric circulation over ice sheets, including katabatic winds. MAR has also led to significant advances in the understanding of the surface mass balance of mid-latitude and tropical glaciers. It has also provided climate simulations over Europe and Africa.
