The Japan Society of Atmospheric Chemistry and the IGAC Subcommittee of the Science Council of Japan plan to publish "Future Vision for Atmospheric Chemistry 2022-2032" around the summer of this year, and would like to present and discuss the overall outline and the proposed structure of the introductory section. The purpose of this document is to summarize the research in the field of atmospheric chemistry that should be promoted in the next 10 years (2022-2032) for the purpose of seeking the truth as a basic science, solving social issues such as climate change and health risks, and contributing to the Future Earth and SDGs. It is intended to be used by researchers in the field as a guidepost for the direction of academic research, as a basis for research proposals, etc., and as a communication tool for promoting collaboration with neighboring academic societies. This document is composed of an introductory and individual topical sections.
Topical sections shall consist of seven chapters, each dealing with long-lived greenhouse gases and stratospheric ozone-depleting substances; short-lived climate forcers; laboratory experiments; integrated science with terrestrial ecosystems; integrated science with oceans; aerosols, radiation and clouds; and science above the stratosphere. The first five of these chapters were discussed at the Fall 2021 Meeting on Atmospheric Chemistry and are being revised based on public comments. On the other hand, the contents of the latter two chapters will be presented and discussed during this JpGU meeting.
The introductory section shall present the mission statement of atmospheric chemistry with a conceptual diagram based on the contents of the topical chapters, and then discusses scientific issues, related social issues, inter-disciplinary collaboration, coordination with international projects, and collaboration with domestic ministries and agencies. In addition, the fundamental issues relevant to the entire research field of earth and planetary sciences, such as strengthening of infrastructure, human resource development, and data science collaboration, shall also be presented. We would like to present the essential aspects of these contents and discuss them with the community.
