"[...] 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)
This 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. The science of the ozone layer and its interactions with halogenated chemical compounds are the primary subjects of this book. This is an updated and expanded edition of a highly praised work.
