This study uses multi-source aerosol datasets, including Modern-Era Retrospective Analysis for Research and Applications version 2 (MERRA-2), Moderate Resolution Imaging Spectroradiometer (MODIS), and Aerosol Robotic Network (AERONET), to conduct a long-term variation assessment of aerosol load, high aerosol load frequency, and dominant aerosol types over Asia. The results indicate that regional aerosol type information with adequate spatial resolution can be combined with aerosol optical depth (AOD) values and heavy aerosol load frequency characterization results to explore the key contributors to air pollution. During the study period, the aerosol load over the North China Plain, Central China, Yangtze River Delta, Red River Delta, Sichuan Basin, and Pearl River Delta exhibited an increasing trend from 2000\u20132009 due to a sharp rise in aerosol emissions with economic development and a declining trend from 2010\u20132019 under stricter energy conservation controls and emissions reductions. The growth of urban\/industrial (UI) type and biomass burning (BB) type aerosol emissions hindered the improvement of the atmospheric environment. Therefore, in future pollution mitigation efforts, focus should be on the control of UI-type and BB-type aerosol emissions. The Indus\u2013Ganges River Plain, Deccan Plateau, and Eastern Ghats show a continuously increasing trend; however, the aerosol load growth rate of the last decade was lower than that of the first decade, which was mainly due to the decrease in the proportion of the mixed type aerosols.<\/jats:p>","DOI":"10.3390\/rs13163116","type":"journal-article","created":{"date-parts":[[2021,8,8]],"date-time":"2021-08-08T21:35:40Z","timestamp":1628458540000},"page":"3116","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Long-Term Variation Assessment of Aerosol Load and Dominant Types over Asia for Air Quality Studies Using Multi-Sources Aerosol Datasets"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3863-3754","authenticated-orcid":false,"given":"Chunlin","family":"Huang","sequence":"first","affiliation":[{"name":"Key Laboratory of Aerospace Thermophysics, Harbin Institute of Technology, Ministry of Industry and Information Technology, Harbin 150001, China"}]},{"given":"Junzhang","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Aerospace Thermophysics, Harbin Institute of Technology, Ministry of Industry and Information Technology, Harbin 150001, China"}]},{"given":"Weiwei","family":"Sun","sequence":"additional","affiliation":[{"name":"Key Laboratory of Aerospace Thermophysics, Harbin Institute of Technology, Ministry of Industry and Information Technology, Harbin 150001, China"}]},{"given":"Qixiang","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory of Aerospace Thermophysics, Harbin Institute of Technology, Ministry of Industry and Information Technology, Harbin 150001, China"}]},{"given":"Qian-Jun","family":"Mao","sequence":"additional","affiliation":[{"name":"School of Urban Construction, Wuhan University of Science and Technology, Wuhan 430065, China"}]},{"given":"Yuan","family":"Yuan","sequence":"additional","affiliation":[{"name":"Key Laboratory of Aerospace Thermophysics, Harbin Institute of Technology, Ministry of Industry and Information Technology, Harbin 150001, China"},{"name":"School of Energy Science and Engineering, Harbin Institute of Technology, Harbin 150001, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"50","DOI":"10.1016\/j.jes.2018.02.003","article-title":"Assessment of column aerosol optical properties using ground-based sun-photometer at urban Harbin, Northeast China","volume":"74","author":"Chen","year":"2018","journal-title":"J.
