Aerosol depolarization ratio and aerosol optical depth (AOD) were measured at Chungli (24.58° N, 121.1° E), Taiwan during the period from 2002–2004. The depolarization ratios of background aerosol have values mostly less than 0.06. The maximum AOD in the altitude range of 0.7 to 2km occurs in the summer (June–August) while between 2 and 5km, the spring (March–May) shows the maximum. The former is mainly related to strong convection and humidity; however the latter is due to anthropogenic aerosols transported from East China and Southeast Asia based on calculations of backward trajectories. This seasonal variation of AOD inferred from different transport mechanisms and aerosol compositions which are supported by the height distributions of aerosol extinction and origins.
