Abstract

The present work aims at studying the local to regional atmospheric pollution transport and transformation processes over the Balkan Peninsula and at tracking and characterizing the main pathways and processes that lead to atmospheric composition formation in the region. The US EPA Models-3 system is chosen as a modelling too, its nesting capabilities applied for downscaling the simulations to a 9 km resolution over Balkans. The TNO emission inventory is used as emission input. Special pre-processing procedures are created for introducing temporal profiles and speciation of the emissions. The Models-3 "Integrated Process Rate Analysis" option is applied to discriminate the role of different dynamic and chemical processes for the pollution from road and ship transport. Some results from several emission scenarios which make it possible to evaluate the contribution of different SNAP are demonstrated as well.
