Abstract
This paper introduces the study on structure of atmospheric boundary layer, data analysis and air quality modeling for urban air pollution such a photochemical smog in the Kanto and other areas, and numerical modeling of regional and transboundary air pollution and development of emission inventory in East Asia. Additionally, the tasks for study on the transboundary air pollution in East Asia are summarized and the future direction of atmospheric environmental research in the mid- and long-term are discussed.
