The burning of biomass - forests, grasslands, and agricultural fields after the harvest - is much more widespread and extensive than previously believed; most biomass burning is thought to be initiated by humans and is on the increase. This comprehensive volume is the first to consider biomass burning as a global phenomenon and to assess its impact on the atmosphere, on climate, and on the biosphere itself. The 63 chapters by 158 scientists - including leading biomass burn researchers from third-world countries, such as Brazil, Nigeria, Zaire, India, and China, where biomass burning is so prevalent - point to biomass burning as a significant driver of global change on our planet.Global Biomass Burning provides a convenient and current reference on such topics as the remote sensing of biomass burning from space, the geographical distribution of burning; the combustion products of burning in tropical, temperate, and boreal ecosystems; burning as a global source of atmospheric gases and particulates; the impact of biomass burning gases and particulates on global climate; and the role of biomass burning on biodiversity and past global extinctions.Also included are contributions on the importance of biomass burning from the International Geosphere-Biosphere Program: A Study of Global Change and from the International Global Atmospheric Chemistry Project, as well as policy options prepared by the U.S. Environmental Protection Agency for managing biomass burning to mitigate global climate change.Joel S. Levine is Senior Research Scientist in the Atmospheric Sciences Division, NASA Langley Research Center and is the Principal Investigator of NASA's research program on global biomass burning, Biospheric Research Program, Office of Space Sciences and Applications.

These proceedings describe the current state-of-the-art of ozone research. A wide range of topics is discussed including: emissions, transport and transformation of precursors of ozone and of ozone itself, the distribution of ozone, the deposition of ozone at the earth's surface, and its effects on man and the environment. Attention is also given to the role of stratospheric ozone and the role of the ultraviolet radiation which is transmitted through the ozone layer. Finally it describes in detail present and future policy measures to reduce the ozone in the lower atmosphere and to protect the ozone layer in the stratosphere. Many of the papers describe recent developments and new research results. Research carried out in both in Europe and in the United States is described, as are the policy measures which are being taken by both European and U.S. governments.

Unter den weltweit fortschreitenden Beeinträchtigungen der natürlichen Lebensbedingungen nimmt die zunehmende Zerstörung der Ozonschicht eine besondere Bedeutung ein. Dieser Text von Gérard Mégie, Professor an der Universität Pierre et Marie Curie in Paris, stellt die komplizierte Chemie der Atmosphäre einfach, aber präzise dar. Die drei Hauptteile geben eine klare Übersicht über das Thema: das natürliche Gleichgewicht der Atmosphäre, das gestörte Gleichgewicht; die Wiederherstellung des Gleichgewichts. Im ersten Teil ist dargestellt, in welchen Prozessen atmosphärisches Ozon gebildet wird. Auf dieser Basis wird im folgenden der Einfluß menschlicher Aktivitäten gut verständlich. Mit der Autorität des Fachmanns stellt Mégie verschiedene Modelle vor, welche die Entwicklung der Atmosphäre und der Ozonkonzentration vorhersagen, und er informiert über die internationale Zusammenarbeit zum Schutz der Ozonschicht. Sterne und Weltraum schreibt zur französischen Ausgabe: "Es gibt wenige populärwissenschaftliche Werke, die mit solcher Genauigkeit und Verständlichkeit ein wichtiges Problem wirklich gut untersuchen

Presented here is an account of industrial and general air pollution problems in view of air quality management, community and industrial health aspects, emission inventorying, emission and air quality measurement techniques, dispersion phenomena and control technologies. Moreover, several case studies from automotive and manufacturing processes as well as some country reports are presented. Finally, the global warming problem (greenhouse effect), atmospheric carbon dioxide build-up and radiation hazards involved in the atmosphere are discussed

Wie groß ist die Belastung von Boden und Luft wirklich? Wie verläßlich sind Klimamodelle? Wie sicher sind Untergrunddeponien? Ist Meeresbergbau vertretbar? Wie verläuft eigentlich eine Umweltverträglichkeitsprüfung? Die Beiträge dieses Buches, von namhaften deutschen Geowissenschaftlern und Meteorologen verfaßt, geben Antwort auf viele drängende Fragen zu Umweltproblemen, mit denen wir inzwischen täglich konfrontiert werden. Die Vielseitigkeit der Themen orientiert sich an der gestörten Eigendynamik des Ökosystems Erde und möchte allen, die sich mit diesen Fragen beschäftigen, die bestehenden Vernetzungen der Teilsysteme Erde und Atmosphäre aufzeigen und Anregungen zum Weiterdenken geben
