Talk Title: Understanding Mars and Venus with a Global Climate Model
A Global Climate Model (GCM) is a convenient and powerful tool for studying any planetary atmosphere.
I will give three examples of its application for Mars and Venus.
First, I will explain how the modeling of water ice clouds unravels the water cycle on Mars, today and in its recent past.
Then, I will present techniques to reconcile a GCM with observations, in particular inside Martian dust storms.
Finally, I will tackle the modeling of mysterious gigantic gravity waves recently seen on Venus.
