An outlook of System for Integrated modeLling of Atmospheric coMposition SILAM v.5

Abstract

Chemical composition of the troposphere is controlled by several major emission sources, such as anthropogenic releases, biogenic gaseous and particulate emission, wild-land fires, wind-driven dust and sea salt emissions, lightning, and transport from the upper atmosphere. These sources contribute to a comparatively limited list of inorganic species and a vast variety of organic substances, which are transported and mixed in the troposphere but also take part in chemical and physical transformations. Due to inter-relation of the transformation processes and synergetic effects of the pollutants impacting human health and ecosystems, modern chemical transport models include a wide range of species, as well as their interactions. This paper presents a new generation of dispersion model SILAM, an open-code system developed at FMI in collaboration with VTT Energy (Finland), Main Geophysical Observatory (Russia), University of Tartu (Estonia), Medical University of Wien (Austria), Danish Meteorological Institute (Denmark). © Springer Science+Business Media Dordrecht 2014.
