Abstract

Dimethylsulphide (DMS), emitted by marine phytoplankton, is the second most important source of atmospheric sulphur, after anthropogenic SO2. In the atmosphere, DMS is transformed into condensable acidic sulphur products and, through gas-to-particle conversion, it becomes the most important natural source of atmospheric sulphate aerosols. Possible climatic effects have been suggested, linked to the negative radiative forcing due to scattering of solar radiation and especially to modification of cloud albedo over oceans by sulphate aerosol particles. These effects occur in addition to those deriving from the superimposed anthropogenic component of the atmospheric sulphate. Understanding the cycle of DMS in the marine troposphere and its interaction with the aerosol budget and cloud properties has become a key research target in these last years. Our knowledge of the many processes involved is still fragmentary, however. This book, which updates the state of our comprehension of the marine DMS cycle with special regard to its climatic impact, will be of interest to marine biologists, atmospheric chemists, aerosol physicists and climatologists, and to scientists concerned with changes in the Earth's climate.

Abstract

Oxidation and removal of atmospheric constituents involve complex sequences of reactions which can lead to the production of photo-oxidants such as ozone. In order to understand and model these complex reaction sequences, it is necessary to have a comprehensive understanding of reaction mechanisms and accurate estimates of kinetic parameters for relevant gas-phase atmospheric reactions. This book presents recent advances in the field and includes the following topics: the oxidation of simple organic compounds, NOx kinetics and mechanisms, OH radical production and rate constants for the OH attack on more complex organic compounds, peroxy and alkoxy radical reactions, photo-oxidation of aromatic and biogenic compounds, the interaction between radical species, the nitrate radical and its role in night-time reactions as well as the sources and sinks of HOx and RO2. This book is volume 3 of the series on Transport and Chemical Transformation of Pollutants in the Troposphere.
