Scientific paper

MarsWRF is a new general circulation model of the Martian atmosphere. A modified, planetary version of the terrestrial, mesoscale Weather Research and Forecasting (WRF) model, MarsWRF can operate as either a limited area or global model, and can be run with higher resolution regions embedded within the outer domain. We will present first results from using the basic global version of MarsWRF to simulate the Martian dust cycle, with two dust lifting processes (near-surface wind stress and dust devils) and with dust as both a passive and an active tracer. In the latter case, we will examine the feedbacks between injected dust and the atmospheric state, and will discuss the realism of the simulations and our future plans for improvement. We will also outline future plans to run MarsWRF with embedded high resolution domains in key lifting areas, and discuss how this will enable us to study multi-scale feedbacks.
