Full-scale Annual N2O dataset in China (FAN2020)

FAN includes N2O emission of five sectors: agriculture, energy, industry, waste and natural ecosystem. Most sectors cover the temporal variations of N2O emissions from 1980 to 2020, and hence the version was named FAN v2020. For anthropogenic sources, FAN follows the categories of each sector in the IPCC-guided methodology, and includes 23 categories for all anthropogenic sources, which are estimated at the provincial level. Natural sources include N2O emission from forest and grassland ecosystem simulated with at a spatial resolution of 25 km×25 km.
