Aerosols during Moscow extreme smoke event of August 2010: physico-chemistry and long range transport in Europe

摘要

Freshly-emitted smoke from experimental fires, aerosols aged in urban atmosphere during extreme smoke event in Moscow, and long range transport of smoke plume to Athens identified by back trajectory analysis are quantified by a number of characteristic groups representative for environmental and climate concern. Together with organic/inorganic composition, ion content, and biomarkers composition they show that smoke aerosols is composed of a broad variety of morphologically and chemically heterogeneous species which undergo physical changes and evolution during transport and aging. The data presented here improve the knowledge about the type of aerosols emitted from wildfires, especially due to frequent break outs in Russia and Europe, leading to extreme smoke episodes, affecting visibility, human health, and mortality.
