The destruction of the ozone layer, together with global warming, is one of the hot environmental topics of today. This book examines the effect of human activities on atmospheric ozone, namely the increase of tropospheric ozone and the general diminution of stratospheric ozone and the production of the Antarctic ozone hole. Also discussed is the role of remote sensing techniques in the understanding of the effects of human activities on atmospheric ozone as well as in the development of social and political awareness of the damage to the ozone layer by man-made chemicals, principally CFCs. This led to the formulation and ratification in 1989 of the Montreal Protocol on controlling/banning the manufacture and use of chemicals that damage the ozone layer. Since then, remote sensing has played a key role in monitoring atmospheric ozone concentration and determining the success of the Montreal Protocol in protecting the ozone layer from further damage. In this book, the renowned authors discuss the sophisticated instruments that have been launched into space to study not only ozone but also other trace gases in the atmosphere, some of which play a key role in the generation and destruction of ozone in the atmosphere. Professors Cracknell and Varotsos also examine the satellite-flown instruments which are involved in monitoring the absorption of solar ultraviolet light in the atmosphere in relation both to the generation and destruction of ozone and consequently to human health. This scholarly book, written by the foremost experts in the field, looks at remote sensing and its employment in the various aspects of ozone science. It is widely acknowledged that global warming, due to anthropogenic greenhouse gases emissions, represents a threat to the sustainability of human life on Earth. However, many other threats are potentially just as serious, including atmospheric pollution, ozone depletion, water pollution, the degradation of agricultural land, deforestation, the depletion of the world's mineral resources and population growth.

Space science in China is one of the most active areas in modern science, and China has played a dynamic and steadily increasing role in this field since the 1960s. Until recently, however, activity in China was a mystery to the rest of the world. With the commercial importance of space, and the fact that space is now used as a laboratory to carry out various experiments, China has recently emerged as an important international competitor. Space Science in China provides a clear understanding of the latest research and progress in such wide-ranging areas as the development and research in solar-terrestrial science, space astronomy, geoscience, remote sensing, microgravity science, and life science.

Atmospheric water plays a key role in climate. Water vapour is the most important greenhouse gas and its condensed forms exert a profound influence on both incoming solar and outgoing infrared radiation. Unfortunately, accurate, height-resolved global-scale measurements of atmospheric humidity are difficult to obtain. The change in concentration of five orders of magnitude form the ground to the stratosphere means there is no standard instrument that will measure everywhere. This has led to different measuring techniques, all with strengths and weaknesses. This book assesses all presently available techniques that are used in monitoring networks. Special weight is given to presenting the different technical concepts, the accuracy of different sensor types, addresses calibration issues and retrieval aspects.

Unlike direct problems related to the solution of differential equations, inverse problems are typically expressed by integral equations. These equations relate media parameters to parameters of a measured signal, or input parameters to output ones in various measurement systems. The solution of integral equations is, with few exceptions, an ill-posed problem, and additional a priori information about the exact solution should be used to solve such problems. The specific character of the a priori information determines various regularisation methods that are in use here to obtain an approximate solution: Tikhonov's method, statistical regularisation method, methods based on the use of additional equations or restrictions or of models with limited number of unknown parameters. The main point of this book is the study of convergence properties of each method and the wide application of numerical modelling that gives the accuracy of the solution in a chosen metric. It is an unaccustomed procedure for physicists, but, because there is no proportionality between data and solution errors in ill-posed problems, such approach is inevitable.

Remote Observing is a new, important, and growing aspect of astronomy. Recent developments in global network communications have made remote observing a viable, and sometimes preferable, alternative to travel to a possibly remote and inhospitable telescope site.This workshop is the first in the world devoted to the topic. The contributors represent many of the world's major telescopes, radio, optical and infrared. The proceedings should become a standard reference for many years on the state of the art in remote control of and data acquisition from astronomical telescopes.
