Riassunto

The "European Experiment on the Transport and Transformation of Environmentally Relevant Trace Constituents over Europe" (EUROTRAC) was established in 1986 to tackle the scientific problem and combine the expertise, knowledge and resources in Europe, in order to apply them over a large region covering the greater part of the continent. EUROTRAC is a coordinated multidisciplinary scientific research project involving field measurements, laboratory studies, instrument development and development of comprehensive computer models for the simulation of the physical and chemical processes in the lower atmosphere.

Dalla quarta di copertina:

Although clouds are known to be effective processors for the production of acidified precipitation and the modification of photooxidant concentrations in the atmosphere, the detailed physical and chemical processes by which the changes occur are still far from understood and are a subject of vigorous current research. This book presents recent advances in the field, including photochemical and free radical reactions in cloud droplets, reaction mechanisms for the oxidation of sulfur(IV) by ozone and hydrogen peroxide, the role of transition metal ions in aqueous oxidation, the exchange of pollutants between air and cloud droplets, and some studies of aerosol surface reactions and photocatalysis. The book is volume 2 of the series on Transport and Chemical Transformation of Pollutants in the Troposphere.
