Abstract

It is known that local spatially and temporally resolved measurements of atmospheric aerosols in Asian urban city are meaningful since the aerosol distribution in East-Asia is complicated due to the increasing emissions of anthropogenic aerosols in association with economic growth and natural dust significantly varies with the seasons. In this work, we intend to show the spatial and temporal variation of atmospheric aerosols in East Asia, especially around AERONET/Osaka site and Dragon-Asia period, named "DRAGON-Osaka". AERONET (Aerosol Robotics Network) Osaka site was established in 2002 in the campus of Kinki University. Nowadays, LIDAR, PM_2.5 / ₁₀ measurements and others are available. The site data are useful for algorithm development of aerosol retrieval over busy city. However, human activities in this region also emit the huge amount of pollutions, thus it is needed to investigate the local distribution of aerosols in this region. In March 2012, to obtain maximum efficiency of DRAGON-Osaka, several Cimels are deployed at more sites as soon as possible. In order to investigate change of aerosol properties, PM-individual analysis is made with scanning electron microscope (SEM) coupled with energy dispersive X-ray analyzer (EDX). A componential analysis presents temporal variation of aerosol properties.
