Concentration of suspended particulate matter less than 2.5 μm (PM2.5) is a representative parameter of air quality. Simultaneous measurements of PM2.5 and the column aerosol optical thickness (AOT) have been performed at a NASA/AERONET station, Higashi-Osaka, Japan since March 2004. They successfully provide a linear correlation between PM2.5 and AOT. A Mie scattering lidar instrument was deployed at the same observational site in April, 2008. It provides us with the attenuated backscattering coefficients of aerosols at wavelengths of 0.532 and 1.064 μm, which indicate the vertical distribution of aerosols. This work intends to improve the correlation between AOT and PM2.5 by using the measurements of lidar.
