Much remains to be explored when it comes to the diversity of exoplanetary atmospheres, much remains to be explored. For a few selected objects such as Proxima Centauri b, first observations of the atmosphere have already been achieved. At the same time, much more information is expected soon with the help of JWST launched in December 2021. However, to interpret existing and upcoming observations, model studies of planetary atmospheres that account for various processes - e.g., atmospheric escape, outgassing, climate, photochemistry, and the physics of air showers - are necessary. Here, we present our unique model suite INCREASE investigating the impact of cosmic rays on diverse exoplanetary atmospheres and their habitability.
