Dry deposition of particles: implications and recommendations for mapping of deposition over Europe

This paper assesses current knowledge about the dry deposition of particles with a focus on implications for Europe. General aspects of sources, physical characterisics and concentration data of particles in the atmosphere are considered. Current modelling approaches for calculating the dry deposition of small and coarse particles are reviewed. Shortcomings and uncertainties of these models are presented. Measurements of small- and large-particle deposition with various techniques are summarized together with their limitations. Finally, implications of scale aspects of particle dry deposition are treated with an emphasis on Europe. -from Authors
