三极地区气溶胶类型数据 V2.0（2006-2021）

三极气溶胶类型数据产品是综合利用MEERA 2同化资料和主动卫星CALIPSO产品经过一系列数据预处理、质量控制、统计分析和对比分析等过程而融合得出的气溶胶类型结果。该气溶胶类型融合算法的关键是对CALIPSO气溶胶类型的判断。气溶胶类型数据融合时根据CALIPSO气溶胶类型的种类和质控，并参考MERRA 2气溶胶类型得到最终的三极地区气溶胶类型数据（共12种）和质量控制结果。该数据产品充分考虑了气溶胶的垂直分布以及空间分布，具有较高的空间分辨率（0.625°×0.5°）和时间分辨率（月）。

The Tri-Polar Aerosol Type Data Product is a fused aerosol type dataset developed by comprehensively integrating MEERA 2 assimilation data and active satellite CALIPSO products through a series of workflows including data preprocessing, quality control, statistical analysis, and comparative analysis. The core of this aerosol type fusion algorithm lies in the classification and judgment of CALIPSO aerosol types. During the data fusion process, the final Tri-Polar region aerosol type dataset (totaling 12 categories) and corresponding quality control results are generated based on the types and quality control flags of CALIPSO aerosol types, with reference to MERRA 2 aerosol types. This data product fully considers both the vertical and spatial distributions of aerosols, and has high spatial resolution (0.625° × 0.5°) and temporal resolution (monthly).
