Short summary
Carbon dioxide and methane drive climate change, but measuring each region's emissions is hard over complex terrain. We combined a detailed computer modeling system with continuous measurements over the Korean Peninsula to estimate both gases. The estimates matched air measurements and agreed with the national carbon dioxide inventory, while suggesting methane from farming and waste may be larger than currently reported. The approach is transferable for national and regional emission monitoring.
