The model uses a fusion machine learning model based on multisource data, including air pollutants, meteorological observations, moderate resolution imaging spectroradiometer (MODIS) aerosol optical depth (AOD) data, and an operational regional atmospheric environmental modeling System for eastern China (RAEMS) outputs. Extreme gradient boosting (XGBoost), a light gradient boosting machine (LightGBM), and a numerical prediction method, i.e., RAEMS were fused to establish this prediction model. Three sets of prediction models, that is, BFM, LightGBM based on multisource data (LGBM), and RAEMS, were used to conduct visibility prediction tasks. The training set was from 1 January 2015 to 31 December 2018 and used several data pre-processing methods, including a synthetic minority over-sampling technique (SMOTE) data resampling, a loss function adjustment, and a 10-fold cross verification. Moreover, apart from the basic features (variables), more spatial and temporal gradient features were considered. The testing set was from 1 January to 31 December 2019 and was adopted to validate the feasibility of the BFM, LGBM, and RAEMS. Statistical indicators confirmed that the machine learning methods improved the RAEMS forecast significantly and consistently. The root mean square error and correlation coefficient of BFM for the next 24\/48 h were 5.01\/5.47 km and 0.80\/0.77, respectively, which were much higher than those of RAEMS. The statistics and binary score analysis for different areas in Shanghai also proved the reliability and accuracy of using BFM, particularly in low-visibility forecasting. Overall, BFM is a suitable tool for predicting the visibility. It provides a more accurate visibility forecast for the next 24 and 48 h in Shanghai than LGBM and RAEMS. The results of this study provide support for real-time operational visibility forecasts.<\/jats:p>","DOI":"10.3390\/rs13112096","type":"journal-article","created":{"date-parts":[[2021,5,27]],"date-time":"2021-05-27T04:30:46Z","timestamp":1622089846000},"page":"2096","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Application of Machine-Learning-Based Fusion Model in Visibility Forecast: A Case Study of Shanghai, China"],"prefix":"10.3390","volume":"13","author":[{"given":"Zhongqi","family":"Yu","sequence":"first","affiliation":[{"name":"Shanghai Typhoon Institute, Shanghai Meteorological Service, Shanghai 200030, China"},{"name":"Shanghai Key Laboratory of Meteorology and Health, Shanghai Meteorological Service, Shanghai 200030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuanhao","family":"Qu","sequence":"additional","affiliation":[{"name":"Shanghai Typhoon Institute, Shanghai Meteorological Service, Shanghai 200030, China"},{"name":"Shanghai Key Laboratory of Meteorology and Health, Shanghai Meteorological Service, Shanghai 200030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunxin","family":"Wang","sequence":"additional","affiliation":[{"name":"Shanghai Typhoon Institute, Shanghai Meteorological Service, Shanghai 200030, China"},{"name":"Shanghai Key Laboratory of Meteorology and Health, Shanghai Meteorological Service, Shanghai 200030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinghui","family":"Ma","sequence":"additional","affiliation":[{"name":"Shanghai Typhoon Institute, Shanghai Meteorological Service, Shanghai 200030, China"},{"name":"Shanghai Key Laboratory of Meteorology and Health, Shanghai Meteorological Service, Shanghai 200030, China"},{"name":"Department of Atmospheric and Oceanic Sciences, Institute of Atmospheric Sciences, Fudan University, Shanghai 200438, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Cao","sequence":"additional","affiliation":[{"name":"Shanghai Typhoon Institute, Shanghai Meteorological Service, Shanghai 200030, China"},{"name":"Shanghai Key Laboratory of Meteorology and Health, Shanghai Meteorological Service, Shanghai 200030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1785","DOI":"10.1016\/0004-6981(81)90214-6","article-title":"Atmospheric visibility","volume":"15","author":"Horvath","year":"1981","journal-title":"Atmos.
