Riassunto

Light is the essential source of information about the surrounding world for most of us. We see objects of di?erent brightness and colours, or, in scienti?c terms, we distinguish objects by the way they re?ect light of di?erent wa- lengths with varying e?ciency. It was exciting for both of us to learn that scienti?c instruments can expand our senses and provide information from this very same radiation that goes far beyond the simple recognition of - jects. Theabilityto“see”thecompositionoftheairsurroundingusandabove our heads, to us and others, one of the most fascinating aspects of the app- cation of modern technology to study the atmosphere. This fascination drove many of the applications of the Di?erential Optical Absorption Spectroscopy (DOAS) method presented in this book, and continues to be the motivation for many current developments. DOAS is an elegant and powerful analytical method to study the at- sphere and is based on the relatively simple principles of classical absorption spectroscopy. It has therefore always been quite surprising to us that this method has not found wider use in atmospheric research and air-quality m- itoring. We have introduced many university students and researchers to DOAS, often wishing that we could improve our e?orts with a comprehensive text that describes both the theoretical basis and the practical applications of the method.

Su questo libro

Dalla quarta di copertina

Measurement techniques form the basis of our knowledge about atmospheric composition and chemistry. Presently, important questions of atmospheric chemistry center on urban pollution, free-radical chemistry, degradation of greenhouse gases and the budgets of tropospheric and stratospheric ozone.

Among the many different optical spectroscopic methods that are in use, DOAS has emerged as a universal technique to measure the concentrations of atmospheric trace gases by making use of the characteristic absorption features of gas molecules along a path of known length in the open atmosphere.

This book reviews the basics of atmospheric chemistry, radiation transport, and optical spectroscopy before detailing the principles underlying DOAS. The second part of the book describes the design and application of DOAS instruments as well as the evaluation and interpretation of spectra. The recent expansion of DOAS application to the imaging of trace gas distributions by ground, aircraft, and satellite-based instruments is also covered.

Written for graduate students and researchers with a general background in environmental physics, this book especially addresses the needs of those working in the field of atmospheric chemistry, pollution monitoring, and volcanology.
