- An interesting feature of the ANICE project is the use of the two complementary atmospheric chemistry transport models, ACDEP and METRAS. This combined modelling effort is expected to lead to a major improvement in the estimate of atmospheric inputs into the North Sea, which can subsequently be used in effect studies.
- Most current models use grids that are too coarse to describe the governing processes with sufficient accuracy, particularly in coastal regions as demonstrated with the ANICE studies (de Leeuw et al., 2001).
- The high dynamics in atmospheric deposition on both spatial and temporal scales and the importance of wet deposition stress the need for a coupling of the deposition and meteorological models.
- The generalisation for Europe-wide applications will require from the models to become more generic. For example, when focus is on nitrogen deposition in the Atlantic zone, a lot of effort is put on the assessment of the P-deposition in the Mediterranean Sea. In the Mediterranean, where abundant cyanophyceae are actively fixing the atmospheric nitrogen, nitrogen is indeed not considered as a limiting factor (Migon et al,. 2001, Markaki et al., 2003) .
