Accurate and timely seasonal warnings are essential to reduce visibility hazards. Here, we develop a seasonal visibility forecast model that takes into account the geographical distance (GDAI). The model is based on an encoder-decoder architecture, integrates geographic distance information, and makes full use of future and historical visibility information and meteorological data to achieve forecasts up to 12 months in advance. The GDAI model consistently outperformed the basic AI model (BAI) across all lead times, demonstrating superior forecasting capabilities. Specifically, GDAI achieved an average increase of 23.06% in R<sup>2</sup>, while the RMSE and MAE were reduced by 22.63% and 40.11%, respectively. GDAI achieves more accurate 12-month visibility forecasts in non-site areas. The average forecast error is reduced by 0.61–1.10 km. GDAI is more reliable than the forecast accuracy of BAI. Verification results in different regions and climate zones show that the accuracy of GDAI is better than that of BAI at more than 70% of the sites. This means that the AI model considering geographic distance can provide earlier visibility seasonal warnings in non-site areas, highlighting the key role of geographic distance in seasonal forecasts. This research not only provides scientific reference for human travel, but also opens up new methods and perspectives for the accurate and seasonal forecasting of major disasters such as global fog seasons and sandstorms.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":36991,"journal":{"name":"Aerosol Science and Engineering","volume":"10 5","pages":"838 - 850"},"PeriodicalIF":2.3,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method improves submicron precision, resists particle agglomeration (validated via PDI), and simplifies procedures by removing test benches, vacuum systems, and manual weighing, while reducing exposure to harmful PM₂.₅ oil aerosols. The approach involves generating oil aerosols, dispersing them in a custom emulsion, and analyzing them using Dynamic Light Scattering (DLS). Stability was optimized via zeta potential measurements, with 96% ethanol achieving over + 10 mV and ensuring reproducibility. Temperature and viscosity were identified as dominant factors affecting particle size, while injection pressure had minimal impact due to choked flow. A rise from 60 °C to 120 °C reduced particle size by ~ 2.5 μm (~ 50%), replicating engine warm-up behavior. Sample size calculations were conducted with a 95% confidence level using MINITAB. To emulate natural polydispersity, a compound oil (Type 3) with a PDI of 1.123 was developed. Validation against a cascade impactor and LAP340 Topas OPC confirmed accuracy.
