Researchers have developed a system to map PM2.5 air quality across Africa by fusing satellite data with reanalysis information. The system uses LightGBM and conformal prediction, trained on over two million records from 404 monitoring sites across 29 countries. This approach aims to quantify prediction uncertainty and identify geographic limitations, providing regional reliability flags to guide air quality monitoring infrastructure expansion and support sustainable development goals.
