摘要：

The spatial-temporal properties of aerosol types over China are studied using the radiance measurements and inversions data at four Aerosol Robotic Network (AERONET) stations in China. Based on a cluster analysis, five aerosol classes were identified including a coarse-sized dominated aerosol type (presumably dust) and four fine-sized dominated aerosol types ranging from non-absorbing to highly absorbing fine aerosols. The optical properties and seasonal variations of these aerosol types are investigated. The results of analysis show that: (1) the highly absorbing aerosols usually occur in winter, (2) non-absorbing aerosols are frequently observed in summer; (3) coarse-sized dominated aerosols are frequently occurred in spring.
