Short summary
Our results showed substantially varied fertilizer-induced soil NOx emissions in 2019 from 0.84 to 2.2 Tg N yr-1 globally. Such variations further lead to 0.1 to 3.3 ppbv summertime ozone enhancement in agricultural hotspot regions and 6.7 ppbv to 16.6 ppbv reductions in global methane concentrations.
