Part love story, part medical mystery, here is Martha Weinman Lear's wrenching follow-up to her bestselling memoir, Heartsounds
It is now possible to determine concentrations of trace constituents and pollutants in the lower atmosphere from space, a development which heralds a new era for tropospheric chemistry.
The authors describe how to develop and validate methods for determining tropospheric trace constituents from satellite data, to encourage the use of these data by atmospheric chemists, and to explore the undoubted synergism which will develop between satellite and ground-based measurements, and will eventually give rise to a permanent observation system for the troposphere. The book comprises several comprehensive overviews, prepared by acknowledged experts in the field, together with a series of individual reports from investigators whose work represents the cutting edge of the subject. A variety of results, giving global distributions of several species and their modelling are reported. Most results stem from ESA satellite data, but there is also an account of the North American work in this field which has mainly concentrated on global distributions of ozone.
It is fair to say that the field, as it develops, will revolutionize the way in which atmospheric chemistry is done. This timely book provides a good introduction for anyone with an interest in the future of the troposphere.
Sound-Power Flow: A Practitioner s Handbook for Sound Intensity Robert Hickling, Sonometrics Inc., USA A comprehensive review of topics involving Sound-Power Flow Sound-power flow (sound intensity) is a vector quantity representing the net flow of sound power in watts per square meter in the direction of sound propagation. Sound Power Flow: A Practitioner s Handbook for Sound Intensity is a practical guide to sound-power flow. It covers computational approaches, using linear rather than logarithmic units, and relates these to practical experiments. The book demonstrates both the uses and advantages of acoustical sensing. Using the fundamental cross-spectral method, the measurement of sound-power flow in air and water is computed and reviewed. Sound-power flow in solids is also computed. Applications of sound-power are discussed, including measuring the sound power of a source, locating primary sources of noise in machinery, determining and locating underwater sources of sound, forward-looking sonar for ships and boats, harbor surveillance, community noise and directional hearing. Key features: Considers applications of sound-power flow. Covers computational approaches and relates these to practical experiments. Reviews measurement of sound-power flow in air and water. Covers computed sound-power flow in solids. Describes directional hearing of mammals and insects. This book is an essential guide to sound-power flow for practitioners and research scientists.
