[A-AS11] Atmospheric Chemistry

Mon. May 26, 2025 3:30 PM - 5:00 PM Exhibition Hall Special Setting (5) (Exhibition Hall 7&8, Makuhari Messe)

convener:Shinichi Enami(University of Tsukuba), Hitoshi Irie(Center for Environmental Remote Sensing, Chiba University), Shigeyuki Ishidoya(Advanced Industrial Science and Technology), Tomoki Nakayama(Graduate School of Fisheries and Environmental Sciences, Nagasaki University), Chairperson:Masao Gen(Chuo University)

This session provides a forum for the presentation of the broad spectrum of tropospheric and stratospheric chemistry, including various research topics (e.g., dynamical processes, air quality and climate), approaches (modeling, field measurements, remote sensing, and laboratory studies), and species (gas and aerosol). This session also provides an opportunity for discussing possible future collaboration with other research fields relevant to atmospheric chemistry. We strongly encourage authors to prepare presentation slides and a poster in English. Oral presentation in English is also welcome.
