[A-AS07] Atmospheric Chemistry

Mon. May 22, 2023 10:45 AM - 12:15 PM Exhibition Hall Special Setting (2) (Exhibition Hall 8, Makuhari Messe)

convener:Yosuke Sakamoto(Kyoto University Graduate School of Global Environmental Studies), Risa Uchida(Japan Automobile Research Institute), Shigeyuki Ishidoya(Advanced Industrial Science and Technology), Yoko Iwamoto(Graduate School of Integrated Sciences for Life, Hiroshima University), Chairperson:Fumikazu Taketani(Japan Agency for Marine-Earth Science and Technology), Nobuyuki Takegawa(Graduate School of Science, Tokyo Metropolitan 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.
