Planetary atmospheres – A roadmap to planets that lost their habitability

There is currently a considerable effort from the science community to study the planetary atmospheres, within and beyond our Solar System. Nevertheless, the knowledge of all mechanisms at work on Solar System planet atmospheres’ is still limited. An understanding of the dominant factors and mechanisms controlling the atmospheric general circulation and its chemical composition is a prerequisite to our understanding of planets’ climate variability and evolution. In this context, Venus, Mars are natural comparative laboratories to investigate diversity of circulation regimes and composition of terrestrial planets’ atmospheres. In this seminar I will address the different temporal evolution path from Solar System rocky planets. I will also present our research related with this topic and with the search for life on the Solar System’s planets and beyond.
