Atmospheric Methane: Its Role in the Global Environment

by Mohammad Aslam Khan Khalil

Methane is an important greenhouse gas that can cause global warming. The present concentrations of methane are nearly three times higher than several hundred years ago. Today, more than 60% of the atmospheric methane comes from human activities, including rice agriculture, coal mining, natural gas usage, biomass burning, and raising of cattle. Methane affects the stratospheric ozone layer and the oxidizing capacity of the atmosphere, which in turn control the concentrations of many man-made and natural gases in the atmosphere. This book brings together our knowledge of the trends and the causes behind the increased levels of methane. Based on the scientific information on the sources and sinks, and the role of methane in global warming, strategies to limit emissions can be designed as part of a program to control future global warming.

Atmospheric Methane: Sources, Sinks, and Role in Global Change (Nato ASI Subseries I: #13)

by M. A. K. Khalil

Methane plays many important roles in the earth's environment. It is a potent "greenhouse gas" that warms the earth; controls the oxidizing capacity of the atmosphere (OH) indirectly affecting the cycles and abundances of many atmospheric trace gases; provides water vapor to the stratosphere; scavenges chlorine atoms from the stratosphere, terminating the catalytic ozone destruction by chlorine atoms, including the chlorine released from the man-made chlorofluorocarbons; produces ozone, CO, and CO2 in the troposphere; and it is an index of life on earth and so is present in greater quantities during warm interglacial epochs and dwindles to low levels during the cold of ice ages. By all measures, methane is the second only to CO2 in causing future global warming. The book presents a comprehensive account of the current understanding of atmospheric methane, and it is an end point for summarizing more than a decade of intensive research on the global sources, sinks, concentrations, and environmental role of methane.

Atmospheric Ozone as a Climate Gas: General Circulation Model Simulations (Nato ASI Subseries I: #32)

by Wei-Chyung Wang Ivar S. Isaksen

One of the major findings in the 1992 IPCC report and the 1994 World Meteorological Organization's Ozone Assessment report was the identification of possible climatic effects over the last few decades resulting from anthropogenic ally-induced changes in atmospheric ozone. The initial quantitative estimates of their direct climatic effects indicate significant impacts, though large uncertainties exist and studies using general circulation models are needed. A point that needs to be addressed in particular is that atmospheric ozone differs from greenhouse gases in that it is formed and destroyed by chemical processes in the atmosphere due to interaction involving a large number of source gases (e. g. H0, NO ' CO, 2 x NMHC, N0, CH and the CFCs). Therefore, the indirect effect of climate-chemistry 2 4 interaction involving atmospheric ozone is an important aspect for consideration in general circulation models. During the last few years, there have been several international workshops related to atmospheric ozone. In 1987, a NATO workshop on atmospheric ozone was held in Lillehammer, Norway. More recently, two workshops were organized to discuss the topic "General Circulation Model Study of Climate-Chemistry Interaction. " The first was held August 19-21, 1992, in Oslo, Norway, and the second held May 26-27,1993, in Albany, New York, USA. The two workshops were IAMAP activities under the Trace Constituent Working Group.

Atmospheric Ozone Dynamics: Observations in the Mediterranean Region (Nato ASI Subseries I: #53)

by Costas Varotsos

An increasing allllo~/allce because of the anthropogenically induced ozone depletion and relevant illcrca5e of the surface ultraviolet (UV) radiation (including erythemal part of the UV spectrum) has resulted in the growth of interest to total ozone (TOZ) surface and satellite observations, surface UV measurements (with an emphasis on UV -B) and. the interpretation of observation results to assess potential impacts of the UV radiation enhancement on man and biosphere. The significance of this phenomenon is diJIcrent in various cowltries. Special attention has been paid, for instance, to ozone depletion and UV radiation increase at high latitudes (this problem has also been discussed during the Workshop). It is equally clear, however, that low and mid-latitude environmental dynamics requires carefuU monitoring and assessment of environm(:ntal trends as well. Such a conclusion is especially true for the Mediterranean Region where numerous resort places are located and subject to excessive levels of Solar Ultraviolet Radiation. This is why the NATO Advanced Rcsearch Workshop "Ground-Level and Satellite Ozone Observations: Changes in the Mediterranean Region" was organized and took place in Athens (Grcccc) during the Lime period 31 October -4 November 1995. It should be pointed out, however, that presentations discussed during the Workshop went far beyond the regional scale of consideration. This has been very important, because it opened an opportwlity to analyse the Mediterrane:an environmental situation in the broader contcx1 of the European global changes.

Atmospheric Physics

by Julio V. Iribarne H.-R. Cho

The extraordinary growth and development of atmospheric sciences during the last dec­ ades, and the concern for certain applied problems, such as those related to the environ­ ment, have prompted the introduction of college and university courses in this field. There is consequently a need for good textbooks. A few appropriate books have appeared in the last few years, aimed at a variety of levels and having different orientations. Most of them are of rather limited scope; in par­ ticular, a number of them are restricted to the field of dynamics and its meteorological applications. There is still a need for an elementary, yet comprehensive, survey of the terrestrial atmosphere. This short volume attempts to fill that need. This book is intended as a textbook that can be used for a university course at a second or third year level. It requires only elementary mathematics and such knowledge of physics as should be acquired in most first-year general physicS courses. It may serve in two ways. A general review of the field is provided for students who work or plan to work in other fields (such as geophysics, geography, environmental sciences, space research), but are interested in acquiring general information; at the same time, it may serve as a general and elementary introduction for students who will later specialize in some area of atmospheric science.

Atmospheric Pollutants in Forest Areas: Their Deposition and Interception

by H. W. Georgii

In November 1981 a first symposium with the topics of "Acid Deposition of Atmospheric Pollutants" was organised in OberursellTaunus to introduce the problems and first results of research-activities on wet and dry deposition of pollutants and on acid precipitation. In the meantime the hazard to forest and vegetation became more dramatic and research-projects to investigate the input of pollutants to forest-ecosystems have been initiated by several interdisciplinary groups. The rapidly increasing interest in the problems of forest­ decay and the many open questions with respect to the diagnosis of the forest-damage were the background for the organisation of a second symposium which was held in November 1985 at the same location in Oberursel/Taunus. It was mainly concerned with new techniques of sampling and analyzing pollutants in forest areas. Besides deposition, one important pathway of pollutants in orographic terrain is the interception of fog-droplets by vegetation. Special emphasis was laid on the chemical composition of fog. The symposium successfully assembled scientists from the field of atmospheric research with those studying the effect of pollutants on trees and vegetation in order to reduce the many open questions in connection with forest desease. The proceedings presented in this volume are a substantial contribution to the understanding of deposition and interception of pollutants in forest-areas. Thanks to the authors the volume contains a lot of new research ·results and presents therefore a true picture of our present knowledge.

Atmospheric Radiation: Theoretical Basis

by R. M. Goody Y. L. Yung

A complete revision of Goody's classic 1964 work, this volume offers a systematic discussion of atmospheric radiation processes that today are at the center of worldwide study and concern. It deals with the ways in which incident solar radiation is transformed into scattered and thermal radiation, and the thermodynamic consequences for the Earth's gaseous envelope, identifying aspects of the interaction between radiation and atmospheric motions as the central theme for atmospheric radiation studies. As a complete treatment of physical and mathematical foundations, the text assumes no prior knowledge of atmospheric physics. The theoretical discussion is systematic, and can therefore be applied with minor extension to any planetary atmosphere.

Atmospheric Science at NASA: A History (New Series in NASA History (PDF))

by Erik M. Conway

This book offers an informed and revealing account of NASA’s involvement in the scientific understanding of the Earth’s atmosphere. Since the nineteenth century, scientists have attempted to understand the complex processes of the Earth’s atmosphere and the weather created within it. This effort has evolved with the development of new technologies—from the first instrument-equipped weather balloons to multibillion-dollar meteorological satellite and planetary science programs. Erik M. Conway chronicles the history of atmospheric science at NASA, tracing the story from its beginnings in 1958, the International Geophysical Year, through to the present, focusing on NASA’s programs and research in meteorology, stratospheric ozone depletion, and planetary climates and global warming. But the story is not only a scientific one. NASA’s researchers operated within an often politically contentious environment. Although environmental issues garnered strong public and political support in the 1970s, the following decades saw increased opposition to environmentalism as a threat to free market capitalism. Atmospheric Science at NASA critically examines this politically controversial science, dissecting the often convoluted roles, motives, and relationships of the various institutional actors involved—among them NASA, congressional appropriation committees, government weather and climate bureaus, and the military.
