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.
