The team develops numerical Global Climate Model and various simulation tools in order to simulate the details of the environment on Planet Mars (temperature, winds, clouds, snow, etc.). The aim of this modelling is high: ultimately to build numerical simulators based only on universal equations, yet able to consistently reproduce the available observations obtained by the space missions that have explored Mars. The goal is to create a realistic virtual planet that behaves like the real one. This allows to predict the Martian environment when needed and to interpret new observations. Visualization of the environment on Planet Mars based on available data and numerical simulations of the diurnal variations and the seasonal variations.
