A Study of Atmospheric Deposition Chemistry: Wet, Dry and Nitrogen Deposition

Abstract

The field observation study of atmospheric deposition chemistry since 1985 was awarded the Academic Prize by the Japan Society of Atmospheric Environment in 2022. This review paper focuses on the following subjects; precipitation chemistry survey from regional or transboundary scales, development of dry deposition velocity calculation program, improvement of dry deposition components measuring method, and estimation of reactive nitrogen deposition. Furthermore, I would like to describe the advantages of regional-based research of the atmospheric environment from the viewpoint of its peculiarity and originality.
