Evaluation of the impact of environmental control measures during large event on atmospheric aerosol contents based on dual stations remote sensing measurements

摘要

The impact of environmental control measures during 26th World University Summer Games on aerosol loadings is analyzed in this work. The aerosol optical depth (AOD), size distributions as well as angstro?m index during and after the games are compared between two measurement stations. The results indicate that the AODs during the games are significate lower than afterwards at two stations. And the comparison of size distribution shows that fine mode aerosols which mainly produced by human activities are obviously declined during the games at both stations.
