摘　　要：基于CALIPSO卫星的气溶胶类型产品,研究和分析台湾海峡海域在2008至2018年期间各类型大气气溶胶的时空分布特征:1) 受北方沙尘气候和季风气候的影响,台湾海峡主导气溶胶类型为清洁大陆型(34%),煤烟型(27%)和沙尘海洋型(15%),合计占比75%以上;2) 不同类型气溶胶的垂直分布特点差别明显:其中清洁海洋型、污染大陆型、沙尘海洋型主要分布在2500米之下,沙尘型、污染沙尘型、煤烟型分布在2500米之上;3) 各类型气溶胶占比时间变化随季节变化明显,主要集中在春季,冬季其次,秋季比冬季略低,夏季最低。The paper studies and analyzes the spatial and temporal distribution characteristics of various types of atmospheric aerosols in the area of Taiwan Strait during the period from 2008 to 2018, based on the aerosol sub-types products from the CALIPSO satellite: 1) The dominant aerosol types in the Taiwan Strait are clean continental (34%), soot (27%), and sandy and dusty oceanic (15%), which accounted for a combined ratio of more than 75%;2) Vertical distribution characteristics of different types of aerosols vary significantly: clean oceanic, polluted continental, and dusty oceanic types are mainly distributed below 2500 meters, while dusty, polluted dusty, and sooty types are distributed above 2500 meters;3) The temporal variation in the percentage of each type of aerosol varies significantly with the seasons, with the main concentration in the spring, followed by the winter, slightly lower in the fall than in the winter, and lowest in the summer.
