Modelling Atmospheric Ammonia using Agricultural Emissions with Improved Spatial Variability and Temporal Dynamic

Spatially explicit time profile for ammonia emission

The spatial allocation was achieved by embedding the agricultural emission model Integrated Nitrogen Tool across Europe for Greenhouse gases and Ammonia Targeted to Operational Responses (INTEGRATOR) into the air pollution inventory Monitoring Atmospheric Composition and Climate -III (MACC-III), thus accounting for differentiation in ammonia emissions from manure and fertilizer application, grazing, animal houses and manure storage systems. The more detailed temporal distribution came from the integration of TIMELINES which provided predictions of the timing of key agricultural operations, including the day of fertilization across Europe. We correlated time profiles with predicted fertilization day for each crop, local meteorology, excessive precipitation and legislative constraints.
