First, the Himawari-8 AOT data were consistent with the AERONET measurements over most of the China Seas, except for some coastal regions. The spatial feature showed that AOT over high latitude seas was generally larger than over low latitude seas, and it is distributed in strips along the coastline and decreases gradually with increasing distance from the coastline. AOT undergoes diurnal variation as it decreases from 9:00 a.m. local time, reaching a minimum at noon, and then begins to increase in the afternoon. The percentage daily departure of AOT over the East China Seas generally ranged \u00b120%, increasing sharply in the afternoon; however, over the northern part of the South China Sea, daily departure reached a maximum of &gt;40% at 4:00 p.m. The monthly variation in AOT showed a pronounced annual cycle. Seasonal variations of the spatial pattern showed that the largest AOT was usually observed in spring and varies in other seasons for different seas.<\/jats:p>","DOI":"10.3390\/rs13245082","type":"journal-article","created":{"date-parts":[[2021,12,14]],"date-time":"2021-12-14T22:06:10Z","timestamp":1639519570000},"page":"5082","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Spatial and Temporal Variations of Aerosol Optical Thickness over the China Seas from Himawari-8"],"prefix":"10.3390","volume":"13","author":[{"given":"Qianguang","family":"Tu","sequence":"first","affiliation":[{"name":"School of Surveying and Municipal Engineering, Zhejiang University of Water Resources and Electric Power, Hangzhou 310018, China"},{"name":"State Key Laboratory of Satellite Ocean Environment Dynamics, Second Institute of Oceanography, Ministry of Natural Resources, Hangzhou 310012, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8271-4987","authenticated-orcid":false,"given":"Yun","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Environmental Studies, University of Illinois Springfield, One University Plaza, Springfield, IL 62703, USA"}]},{"given":"Jing","family":"Guo","sequence":"additional","affiliation":[{"name":"Marine Monitoring and Forecasting Center of Zhejiang, Hangzhou 310012, China"}]},{"given":"Chunmei","family":"Cheng","sequence":"additional","affiliation":[{"name":"School of Surveying and Municipal Engineering, Zhejiang University of Water Resources and Electric Power, Hangzhou 310018, China"}]},{"given":"Liangliang","family":"Shi","sequence":"additional","affiliation":[{"name":"School of Surveying and Municipal Engineering, Zhejiang University of Water Resources and Electric Power, Hangzhou 310018, China"}]},{"given":"Yunwei","family":"Yan","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Satellite Ocean Environment Dynamics, Second Institute of Oceanography, Ministry of Natural Resources, Hangzhou 310012, China"},{"name":"Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai), Zhuhai 519000, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5022-7380","authenticated-orcid":false,"given":"Zengzhou","family":"Hao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Satellite Ocean Environment Dynamics, Second Institute of Oceanography, Ministry of Natural Resources, Hangzhou 310012, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1308","DOI":"10.1016\/j.atmosenv.2009.12.011","article-title":"A European Aerosol phenomenology-3: Physical and Chemical Characteristics of Particulate Matter from 60 Rural, Urban, and Kerbside Sites across Europe","volume":"44","author":"Putaud","year":"2010","journal-title":"Atmos.
