[A-AS11] Atmospheric Chemistry

Fri. May 27, 2022 1:45 PM - 3:15 PM 201A (International Conference Hall, Makuhari Messe)

convener:Risa Uchida(Japan Automobile Research Institute), convener:Yosuke Sakamoto(Kyoto University Graduate School of Global Environmental Studies), Yoko Iwamoto(Graduate School of Integrated Sciences for Life, Hiroshima University), convener:Shigeyuki Ishidoya(Advanced Industrial Science and Technology), Chairperson:Hitoshi MATSUI(Graduate School of Environmental Studies, Nagoya 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.
