Cette synthèse retrace l'histoire des travaux de recherches menés sur l'ozone atmosphérique. Ceux-ci ont permis de comprendre les processus impliqués dans la formation, la destruction et le transport de la molécule dans la stratosphère, contribuant ainsi à la sauvegarde de cette couche protégeant la surface terrestre du rayonnement solaire ultraviolet.

This book, written by an international group of experts from China, Europe and the USA, presents a broad and comprehensive analysis of the chemical and meteorological processes responsible for the formation of air pollutants in eastern Asia, and in particular for the development of severe pollution episodes observed primarily during winter in the northeastern part of China. With the rapid population growth, economic development and urbanization occurring in Asia, air pollution has become a major environmental problem in this part of the world. The book is organized around six distinct parts. The first part of the volume offers a general perspective on issues related to air pollution including persistent haze events in eastern and southern Asia. The second part presents an overview of air pollution sources (i.e., anthropogenic and biomass burning sources). The third part analyzes in-situ observations of chemical species in China, while the fourth part focuses on space observations of gas-phase and aerosol species. The modeling aspects are treated in the fifth part of the volume, which includes a presentation of several air quality forecast systems and an assessment of the role of urbanization on air pollution levels. Finally, the effects of air pollution on health and crop productivity in China are discussed in the last part of the book. The book also presents an integrated view of past and present situations in Asia and provides the scientific basis from which mitigation policies can be established and air quality can be improved. Audience: This book is written for scientists, educators, students, environmental managers, policy-makers and leaders in public administration and private corporations who wish to use science-based information to mitigate air pollution. The book should help decision-makers to design effective policies for air quality improvement and to successfully manage short-term air pollution episodes that substantially affect people’s quality of life and strongly impact the economy. .

Erstmals trägt dieses nationale Assessment den Forschungsstand zum Klimawandel umfassend für alle Themenbereiche und gesellschaftlichen Sektoren zusammen. Womit müssen wir in Deutschland rechnen, welche Auswirkungen werden die Klimaveränderungen auf Wirtschaft und Gesellschaft haben, und wie können wir uns wappnen? 126 Autoren aus ganz Deutschland äußern sich zu Themen wie bereits beobachtete und zukünftige Veränderungen, Wetterkatastrophen und deren Folgen, den Projektionen für die Zukunft, den Risiken sowie möglichen Anpassungsstrategien. Die Autoren stellen in verständlicher Sprache den aktuellen Forschungsstand dar und veranschaulichen die wichtigsten Gedanken in Grafiken und Tabellen. Alle Texte wurden mehrfach wissenschaftlich begutachtet. Klimawandel in Deutschland ist die erste Gesamtschau zu dem Themenkomplex, benennt offene Fragestellungen und liefert eine Grundlage für Entscheidungen im Zusammenhang mit dem Klimawandel. Deutschland reiht sich damit ein in die Liste von Ländern wie die Vereinigten Staaten, Österreich und Großbritannien, in denen derartige Berichte bereits vorliegen. Die Herausgeber: Prof. Dr. Guy Brasseur und Prof. Dr. Daniela Jacob, ehemaliger Direktor und gegenwärtige Direktorin des Climate Center Germany/Helmholtz-Zentrum Geesthacht, und Susanne Schuck-Zöller, die auch die Projektleitung übernommen hat, werden bei diesem Buch unterstützt von einem Editorial Board, dem elf herausragende Wissenschaftler aus den wichtigsten Klimaforschungseinrichtungen in Deutschland angehören.

Since the Industrial Revolution the chemical composition of the atmosphere has changed at a rate unprecedented in recent history. Ozone depletion emerged as one of the most important environmental issues of the 20th century as evidence grew for substantial human influences on the atmospheric ozone abundances over much of the globe. The science of the ozone layer and its interactions with halogenated chemical compounds are the primary subjects of this book. The volume provides a comprehensive view of the chemical, dynamical, and radiative processes that affect ozone and other chemicals in the stratosphere and mesosphere. Over recent decades our understanding of these processes has increased dramatically. The discovery of the Antarctic ozone hole has shown that human activities can lead to major changes in our environment. From a review of a previous edition - "[ ¦] an interesting and well-written overview of the current status of our knowledge of the composition of the middle atmosphere and the basic radiative, dynamical and photochemical processes which maintain it." (Bulletin American Meteorological Society)
