Book Description
The spectral reflectance of snow in the range of 0.60 to 2.50 micrometers wavelengths was studied in a cold laboratory using natural snow and simulated preparations of snow. A white barium sulfate powder was used as the standard for comparison. The high reflectance (usually nearly 100%) of fresh natural snow in the visible wavelength declines rapidly at wavelengths near and beyond 0.80 micrometers, as the spectral absorption coefficients of ice increase. The rate of decline of near-infrared reflectance due to aging is strongly affected by the history of the snow during aging. Snow aged under certain conditions may retain 90% or so of its reflectance in the visible red, yet may be only about 10% as reflective as the original fresh snow beyond 2.2 micrometers. Several environmental factors such as ambient temperature and wind effects which contribute to the variability in snow reflectance are discussed.

Book Description
Comprehensive Remote Sensing, Nine Volume Set covers all aspects of the topic, with each volume edited by well-known scientists and contributed to by frontier researchers. It is a comprehensive resource that will benefit both students and researchers who want to further their understanding in this discipline. The field of remote sensing has quadrupled in size in the past two decades, and increasingly draws in individuals working in a diverse set of disciplines ranging from geographers, oceanographers, and meteorologists, to physicists and computer scientists. Researchers from a variety of backgrounds are now accessing remote sensing data, creating an urgent need for a one-stop reference work that can comprehensively document the development of remote sensing, from the basic principles, modeling and practical algorithms, to various applications. Fully comprehensive coverage of this rapidly growing discipline, giving readers a detailed overview of all aspects of Remote Sensing principles and applications Contains ‘Layered content’, with each article beginning with the basics and then moving on to more complex concepts Ideal for advanced undergraduates and academic researchers Includes case studies that illustrate the practical application of remote sensing principles, further enhancing understanding

Book Description
The inaugural winner of The Novel Prize, an international biennial award established by Giramondo (Australia), Fitzcarraldo Editions (UK) and New Directions (USA). Cold Enough for Snow was unanimously chosen from over 1500 entries. A novel about the relationship between life and art, and between language and the inner world – how difficult it is to speak truly, to know and be known by another, and how much power and friction lies in the unsaid, especially between a mother and daughter. A young woman has arranged a holiday with her mother in Japan. They travel by train, visit galleries and churches chosen for their art and architecture, eat together in small cafés and restaurants and walk along the canals at night, on guard against the autumn rain and the prospect of snow. All the while, they talk, or seem to talk: about the weather, horoscopes, clothes and objects; about the mother’s family in Hong Kong, and the daughter’s own formative experiences. But uncertainties abound. How much is spoken between them, how much is thought but unspoken? Cold Enough for Snow is a reckoning and an elegy: with extraordinary skill, Au creates an enveloping atmosphere that expresses both the tenderness between mother and daughter, and the distance between them. 'So calm and clear and deep, I wished it would flow on forever.' — Helen Garner 'Rarely have I been so moved, reading a book: I love the quiet beauty of Cold Enough for Snow and how, within its calm simplicity, Jessica Au camouflages incredible power.' — Edouard Louis 'Au’s prose is elegant and measured. In descriptions of bracing clarity she evokes ‘shaking delicate impressions’ of worlds within worlds that are symbolic of the parts of ourselves we keep hidden and those we choose to lay bare. Put simply, this novel is an intricate and multi-layered work of art — a complex and profound meditation on identity, familial bonds and our inability to fully understand ourselves, those we love and the world around us.' — Jacqui Davies, Books+Publishing

Book Description
This book explains in a didactic way the basic concepts of spectral mixing, digital numbers and orbital sensors, and then presents the linear modelling technique of spectral mixing and the generation of fractional images. In addition to presenting a theoretical basis for spectral mixing, the book provides examples of practical applications such as projects for estimating and monitoring deforested areas in the Amazon. In its seven chapters, the book offers remote sensing techniques to understand the main concepts, methods, and limitations of spectral mixing for digital image processing. Chapter 1 addresses the basic concepts of spectral mixing, while chapters 2 and 3 discuss digital numbers and orbital sensors such as MODIS and Landsat MSS. Chapter 4 details the linear spectral mixing model, and chapter 5 talks about how to use this technique to create fraction images. Chapter 6 offers remote sensing applications of fraction images in deforestation monitoring, burned-area mapping, selective logging detection, and land-use/land-cover mapping. Chapter 7 gives some concluding thoughts on spectral mixing, and considers future uses in environmental remote sensing. This book will be of interest to students, teachers, and researchers using remote sensing for Earth observation and environmental modelling.

Book Description
Environmental Chemistry is a relatively young science. loteTest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topies which are based on chemistry embodied in this subject. One of the first objectives of Environmental Chemistry must be the study of the environment and of natural chemieal processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Environmental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysieal modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce targe quantities of waste in relatively small and confined areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.
