Changes in biomass burning, wetland extent, or agriculture drive atmospheric NH3 trends in select African regions
16 November 2021
Ammonia (NH3) gas emitted from soils and biomass burning contributes to particulate air pollution. The authors used satellite observations of the atmosphere over Africa to show that declines in NH3 concentrations over South Sudan's Sudd wetland in 2008–2017 are related to variation in wetland extent. They also find NH3 concentrations increased in West Africa as a result of biomass burning and increased in the Lake Victoria region, likely due to agricultural expansion and intensification.
