[A-AS09] Atmospheric Chemistry

Mon. May 27, 2024 10:45 AM - 12:15 PM 104 (International Conference Hall, Makuhari Messe)

convener:Hitoshi Irie(Center for Environmental Remote Sensing, Chiba University), Tomoki Nakayama(Graduate School of Fisheries and Environmental Sciences, Nagasaki University), Shigeyuki Ishidoya(Advanced Industrial Science and Technology), Shinichi Enami(University of Tsukuba), Chairperson:Takuma Miyakawa(Japan Agency for Marine-Earth Science and Technology)

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.
