| Zusammenfassung |
| Deriving a parameterisation of ammonia emissions for use in
chemistry-transport models (CTMs) is a complex problem as the emission
varies locally as a result of local climate and local agricultural
management. In current CTMs such factors are generally not taken into
account. This paper demonstrates how local climate and local management can
be accounted for in CTMs by applying a modular approach for deriving data as
input to a dynamic ammonia emission model for Europe. Default data are
obtained from information in the RAINS system, and it is demonstrated how
this dynamic emission model based on these input data improves the NH3
calculations in a CTM model when the results are compared with calculations
obtained by traditional methods in emission handling. It is also shown how
input data can be modified over a specific target region resulting in even
further improvement in performance over this domain. The model code and the
obtained default values for the modelling experiments are available as
supplementary information to this article for use by the modelling community
on similar terms as the EMEP CTM model: the GPL licencse v3. |
