Optical Properties of Aerosols in the East China Seas
Aerosol optical properties affect the ability of aerosols to absorb and scatter solar radiation,and therefore the environmental and climatic effects of different types of aerosols vary significantly.In the current study the aerosol data prod-ucts from the cloud-aerosol lidar and infrared pathfinder satellite observations(CALIPSO)satellite were used to analyze the distribution of aerosol optical properties and types in the East China Seas from March 2008 to February 2021.The results showed that the aerosol optical depth in the Bohai Sea and the Yellow Sea was large and the seasonal variation was not obvi-ous,while the aerosol optical depth in the East China Sea was relatively small and the seasonal differences were large;the particle depolarization ratio and the color ratio of aerosols in the three seas were the largest in spring.The Bohai Sea and the Yellow Sea were dominated by dust in spring and dusty marine in other seasons,the East China Sea was most affected by dusty marine in spring,while clean marine dominated in other seasons.The optical depth of dust and dusty Marine aerosols was large with large particles and non-spherical particles,while the optical depth of clean marine aerosols was smaller with particles of spherical shapes.It can be concluded that different types of aerosols have different optical properties,which is of great significance for understanding the energy balance in the atmosphere and predicting climate change.
