The project focuses on three work-packages:

The first work-package concerns the process-base modeling of physical, chemical and biological process at the field scale. It involves the coupling of two models developed at the UMR EcoSys: Volt'Air, the process-based predictive model of ammonia volatilization on bare soil and SurfAtm, the SVAT model (soil-vegetation-atmosphere transfer) for the description of the exchange of ammonia between the soil, the plant and the atmosphere.
The second work-package relates to the implementation of geographical information system (GIS) methods including the crossing of the information layers to map and generate the model inputs. It implies the constitution of several geo-referenced databases: soil, climate, land-use and management. The project will particularly focus on the cultural practice database, as a consequence of the lack of references on organic fertilization practices in France.
The last work-package concerns the generation of the dynamic and spatially-explicit emission inventories. A methodological component should allow analyzing to what extent the aggregation and the loss of information related to the change of scale alter the values of the emissions. Finally, we will apply this approach to the prospective study of the effect of the implementation of the policies/guidelines for abating ammonia emissions (annex IX of the Gothenburg Protocol (1999)).
