Book Description

This excellent book covers techniques used for extrapolating measurements of trace gas fluxes and factors regulating the production, consumption and exchange of trace gases in terrestrial and aquatic environments.It provides a comprehensive summary of all aspects of scaling, from flux measurement techniques, geographic data, modelling, use of tracers and isotopes, inverse modelling and satellite-borne atmospheric observations. An interesting feature of the book is the fact that both fluxes from terrestrial and aquatic (marine) sources are discussed, along with the uncertainties in estimates of trace gas fluxes at different scales, including point, field, landscape, regional and global scale.As well as reviewing the state of the art in the field of scaling of fluxes of greenhouse gases, ozone and aerosol and their precursors, and acidifying compounds, the emphasis of this volume is on identification of gaps in knowledge, finding solutions, and determination of future research directions.

Book Description

Atmospheric abudance of trace gases since the pre-industrial time has forced the earth's climate to change, threatening food security. Exchange of biogenic trace gases between the atmosphere and the biosphere is directly or indirectly influenced by the plants. This volume contains the latest findings on the correlation between the climate change and biogenic gas emission, plant response to elevated levels of carbon dioxide, temperature, ozone and UV-B in combination and alone, regulatory mechanism of methane, nitrous oxide and ammonia emission and their mitigating options. Ecologists, atmospheric scientists, plant physiologists, research scholars, teachers and post-graduate students will benefit from this book.

Book Description

Trace gases are those that are present in the atmosphere at relatively low concentrations. Small changes in their concentrations can have profound implications for major atmospheric fluxes, and thereore, can be used as indicators in studies of global change, global biogeochemical cycling and global warming. This new how-to guide will detail the concepts and techniques involved in the detection and measurement of trace gases, and the impact they have on ecological studies. Introductory chapters look at the role of trace gases in global cycles, while later chapters go on to consider techniques for the measurement of gases in various environments and at a range of scales. A how-to guide for measuring atmospheric trace gases. Techniques described are of value in addressing current concerns over global climate change.

Book Description

Many trace gases are exchanged between the atmosphere and the biosphere. Although much research has been published on the photosynthetic exchanges of carbon dioxide, oxygen, and water vapor, this book focuses on the importance of biogenic trace gases on atmosphere chemistry and ecosystem stability. Included are methane and its effect on the radiative properties of the atmosphere, hydrocarbons (isoprene and monoterpenes), and their role in the production of ozone and carbon monoxide. Also covered are sulfur and nitrogen gases, both of which can lead to ecosystem acidification. The biochemistry and physiology of production of these and other gases are investigated. Plant physiologists, ecologists, and atmospheric chemists and modelers will benefit from this book.
