Multi-Air Pollution Risk Index in Southeast Asia Region

Multi-air pollution risk index product for CO, NO2, and SO2 based on Sentinel-5P remote sensing data from 2019 to 2020 in Southeast Asia region was developed by integrating hazard, vulnerability, and exposure analyses. Eight stages of data processing were used in this study, which yielded the hazard index, air pollution statistics, the vulnerability index, and the risk index. In addition, data validation, air pollution risk opportunities, and time-series data in rural and urban areas were obtained. Data integration generally use the Google Earth Engine.本研究以2019至2020年东南亚区域的哨兵-5P（Sentinel-5P）遥感数据为基础，整合危险性、暴露性与脆弱性分析方法，构建了针对一氧化碳（CO）、二氧化氮（NO₂）、二氧化硫（SO₂）的多污染物大气污染风险指数产品。本次研究共设置8个数据处理阶段，最终得到灾害危险性指数、大气污染统计数据集、脆弱性指数与风险指数。此外，本研究还完成了数据验证工作，并获取了城乡区域的大气污染风险机遇及时序数据。数据集成工作整体依托谷歌地球引擎（Google Earth Engine）开展。
