Session Proposal: The Synergy among Theoretical Methods, Laboratory Studies and Atmospheric Modeling: Chemistry, Photochemistry and Cloud Processes in Planetary Atmospheres (AGU25)

P043
The Synergy among Theoretical Methods, Laboratory Studies and Atmospheric Modeling: Chemistry, Photochemistry and Cloud Processes in Planetary Atmospheres

Session ID#: 247996

Session Description:
The study of planetary atmospheres is more vibrant than ever. With the James Webb Space Telescope (JWST) measuring the chemical composition of exoplanetary atmospheres, and with several current and upcoming missions to solar system bodies like Venus, Jupiter and Titan, the importance and timeliness of this field is clear. A crucial aspect of studying planetary atmospheres is modeling their atmospheric chemistry and aerosol/cloud formation processes. This includes both comprehensive atmospheric modeling and investigations into fundamental chemical processes to better constrain these models. We invite abstract submissions that involve modeling the atmospheric chemistry of planetary bodies beyond Earth. This can include, but is not limited to, atmospheric chemical and photochemical modeling, laboratory studies on chemistry and photochemistry processes relevant to planetary atmospheres, and computational simulations of chemistry and photochemistry pertinent to these environments. The session is open to research aimed at advancing our understanding of planetary atmospheric chemistry beyond Earth.
