A global high‐resolution emission inventory for ammonia

A global emissions inventory for ammonia (NH 3 ) has been compiled for the main known sources on a 1° × 1° grid, suitable for input to global atmospheric models. The estimated global emission for 1990 is about 54 Tg N yr −1 . The major sources identified include excreta from domestic animals (21.6 Tg N yr −1 ) and wild animals (0.1 Tg N yr −1 ), use of synthetic N fertilizers (9.0 Tg N yr −1 ), oceans (8.2 Tg N yr −1 ), biomass burning (5.9 Tg N...
