P44B:
Planetary Atmospheres and Evolution I


Submit an Abstract to this Session


Session ID#: 60191

Session Description:
Understanding the nature and variability of planetary atmospheres, the physical mechanisms governing these atmospheres, and their evolution are strong driving forces of planetary sciences and solar system exploration mission planning. While the long-term evolution of the Earth is constrained by geological studies and isotopic analyses, the evolutionary paths of other planets must be reconstructed from data obtained through astronomical observations and planetary missions. Models of planetary atmospheres use these observations to illuminate governing physical processes operating from the Earth to planets in our solar system and beyond. The rapidly increasing number of discovered exoplanets provides a new opportunity for interdisciplinary collaborations between geoscientists, astronomers, biologists, and planetary scientists concerning the evolution of planetary atmospheres and planetary habitability. This session welcomes observational, theoretical, experimental, and field studies relevant to the evolution of planetary atmospheres and habitability, in and outside of our solar system (including the Earth).
