Nitrous oxide (N2O) emissions from inland waters remain a major source of uncertainty in global greenhouse gas budgets. In the paper published in the journal Global Change Biology a novel mechanistic modeling approach is presented to explicitly predict the N2O production and emissions via nitrification and denitrification in rivers, reservoirs, and estuaries. The global inland water N2O emissions estimated with this approach are 10-20 Gmol per year, with reservoirs releasing the most N2O per unit surface area. These results indicate that the existing N2O emissions of the International Panel on Climate Change (IPCC) are likely overestimated by up to an order of magnitude.
