2）数据来源：数值模拟，加工方法：基于CALIPSO卫星垂直观测和全球气溶胶模式，通过四维局地集合转换卡尔曼滤波同化方法产生；
3）数据质量良好；
4）该气溶胶同化数据时空覆盖完整，可用于泛第三极地区气溶胶及其化学组分的时空分布特征及其演变规律研究，还可用于气溶胶-云互馈对降水和水汽输送及其辐射、气候以及环境效应研究。

1) Optical depth, vertical mass concentration, and extinction coefficient of dust, sulfate, organic carbon, black carbon, sea salt aerosols, and total aerosols;
2) Data source: Numerical simulation. Processing approach: Derived from vertical observations of the CALIPSO satellite and global aerosol models via the four-dimensional local ensemble transform Kalman filter assimilation method;
3) The data has sound quality;
4) This aerosol assimilation dataset features complete spatiotemporal coverage, and is suitable for studying the spatiotemporal distribution characteristics and evolutionary laws of aerosols and their chemical components in the Pan-Third Pole region, as well as investigating the impacts of aerosol-cloud feedbacks on precipitation, water vapor transport, and their associated radiative, climatic and environmental effects.
