亚洲多角度偏振卫星粗模态气溶胶光学厚度565nm数据集（2005-2013年）

针对亚洲地区气溶胶大尺度空间观测不足，气溶胶气候学特征研究不充分等问题，利用POLDER/PARASOL卫星资料区分了亚洲地区粗细模态气溶胶光学特性参数空间分布特征的气候学特征，并利用地基观测对卫星反演产品进行了系统性验证，获得的粗模态气溶胶光学特性产品有助于研究亚洲区域风尘气溶胶空间分布特征及其演变规律，为开展卫星估算PM10浓度奠定基础。

To address the issues of insufficient large-scale spatial observations of aerosols and inadequate studies on aerosol climatological characteristics over the Asian region, this work utilized POLDER/PARASOL satellite data to discriminate fine and coarse aerosol modes and characterize the climatological features of the spatial distributions of their optical property parameters across Asia. Systematic validation of the satellite-retrieved products was conducted using ground-based observations. The developed coarse-mode aerosol optical property products can facilitate research on the spatial distribution patterns and evolutionary regularities of dust aerosols over the Asian region, laying a solid foundation for satellite-based estimation of PM10 concentrations.
