Abstract

This study was based on two-year MODIS aerosol optical depth (AOD) product and PM₁₀ mass concentrations calculated from Air Pollutant Index (API) in Beijing and the hourly averaged measurements at Peking University in Beijing and Yuen Long station in Hong Kong. The direct correlation between AOD and PM₁₀ mass concentration was found relatively low. The correlation coefficient between aerosol surface extinction (achieved from dividing AOD by seasonal aerosol scalar heights) and PM₁₀ mass concentration increased to some extent. The correlation further improved after considering the influence of relative hfumidity (RH) on aerosol optical properties. This comparison verified that the MODIS AOD can be applied in the evaluation of surface PM₁₀ mass concentration after taking aerosol vertical distribution and influence of RH into consideration.
