Abstract

In order to analyze the urban atmospheric particles in Asia, we have undertaken simultaneous measurements of aerosols and suspended particulate matter (SPM) at a NASA/AERONET station at Kinki University Campus, Higashi-Osaka, since March in 2004. The relationship between concentration of suspended particulate matter (PM) and column aerosol optical thickness (AOT) is examined. It is found that a strong linear correlation exists between PM and AOT, and better correlation is obtained for the aerosols with the same origin, such as anthropogenic aerosols and dusts, rather than overall. The derived regression lines between PM<SUB>2.5</SUB> and AOT highlight the possibility that the PM<SUB>2.5</SUB> concentration can be estimated from the AOT, and vice versa. As a result, a distribution map of PM<SUB>2.5</SUB> has been obtained by using AOT values derived from Terra/MODIS data observed in April 2006 over East Asia.
