An integrated model study for Europe and North America using the Danish Eulerian Hemispheric Model with focus on intercontinental transport of air pollution

► We model the air pollution in North America and Europe for the year 2006 using DEHM. ► We evaluate the model results against measurements for Europe for all available species. ► The evaluation leads to conclusions on where to improve the model. ► We calculated the intercontinental transport of air pollution between North America and Europe. ► We found that the exchange of air pollution between the two continents is small on the annual basis.
