The Mars dust cycle, including dust storms, has a great impact on the temperature, and the climate in general, on Mars. Dust particles in the atmosphere have a great capacity for absorbing/emitting infrared radiation resulting in large changes in the Martian climate. Local and regional dust storms occur in any Martian Year (MY), but global dust storm events (GDEs), which can cover the whole planet, occur, on average, once every 3-4 MYs. MarsWRF is a Mars version of the terrestrial numerical weather and climate model WRF (Weather Research and Forecasting Model) and part of the Planet WRF models for planetary atmosphere research. This requires model calibration by trial and error. The main focus is the formation of global dust storm events. The technique is to run MarsWRF in interactive dust mode. This requires the model user to self-specify the model parameters of the surface dust lifting by dust storms and dust devils. In this thesis, the MarsWRF model is run in interactive dust mode at the classical resolution of 7.5°×9° (latitude by longitude). The resulting dust storms will be compared against higher resolution simulations in Gebhardt et al. (2020).
