Simultaneous monitoring of aerosols and PM2.5 over Osaka

For a better understanding of aerosols, simultaneous measurements of aerosols and suspended particulate matter(SPM) have been undertaken at Kinki University campus in Higashi-Osaka. The relationship between aerosol properties obtained from radiometry with a multi-spectral photometer as a NASA/AERONET station and SPM concentrations such as TSP, PM10, PM2.5, and OBC with SPM-613D (Kimoto Electric) is examined. It is found that there is a linear correlation between SPM concentrations and aerosol properties, which indicates that aerosol characteristics can be estimated from SPM data, and vice versa. It is also shown that the air quality of the Higashi-Osaka site is poor due to not only anthropogenic particles produced by local emissions, such as diesel vehicles and chemical industries, but also due to dust particles coming from continental desert areas by large scale climatic conditions. As a result, long term simultaneous monitoring of aerosols and SPM provides us with three types of particles according to the season for atmospheric aerosols at an industrial city of Higashi-Osaka.
