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.

本研究基于2019至2020年东南亚区域的哨兵-5P（Sentinel-5P）遥感数据，通过整合危险性、脆弱性与暴露性分析方法，构建了针对一氧化碳（CO）、二氧化氮（NO2）、二氧化硫（SO2）的多空气污染风险指数产品。本研究共开展8个阶段的数据处理流程，最终得到危险性指数、空气污染统计数据集、脆弱性指数与风险指数。此外，本研究还完成了数据验证，获取了空气污染风险机遇相关数据以及城乡区域的时序数据。数据整合工作主要依托谷歌地球引擎（Google Earth Engine）完成。
