Abstract
In this work, a set of retrieval methods for evaluating the aerosol mass concentration suitable for high-pollution areas is used to study the vertical distribution of the PM(2.5 )mass con-centration in different regions of East Asia from 2007 to 2016,high-resolution satellite active remote sensing data. Research has revealed that high-pollution areas in East Asia are located mainly in the Taklamakan Desert, northern India, and northern China, followed by Southeast Asia and southern China. The aerosol thick-ness in the dust source areas of eastern China is generally 4 km, with an average PM(2.5 )mass concentration of 60.3 mu gm(-1) in the aerosol layer. In densely populated areas, the aerosol thickness is 2 km, with an average PM(2.5 )mass concentration of 40.9 mu gm(-1 )in the aerosol layer. Results from this work can be used for further analysis of the aerosol effects on weather and climate in East Asia.
