This book describes the processes of radio propagation and analyzes the equations that enable estimation of media. It explores propagation processes and related phenomena including absorption, refraction, reflection, and scattering. It also analyzes how knowledge of radiowave properties allows accurate estimations of media via inverse problems. The text examines the empirical methods that interpret remote sensing data, and how they are applied in the creation of useful approximation models. The authors also describe the operational principles of microwave devices used in remote sensing, and provide insight into the stabilizing a priori information that greatly increases the accuracy of remote sensing solutions.

This volume contains a collection of refereed papers which were presented at the Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment, 14--17 February 1994, Rome, Italy. The last decade has marked a period of steady advancement and new developments in the observation of the terrestrial environment by passive microwave sensors. Both ground-based and satellite-borne systems have improved their accuracy, stability and spatial resolution and are providing a wealth of quantitative data, which are increasingly being employed in application-oriented projects. The contributions in this volume cover different fields of applications of microwave radiometry, the various observation and retrieval techniques and the recent technological developments. The articles are divided into four sections: measurement of atmospheric water vapor and cloud liquid, measurement of rain, observation of the surface, and new radiometric systems.

The capability of the microwave radiometric method to determine soil moisture and vegetation biometric indices was revealed a quarter of a century ago by the author and many of his colleagues. In light of many research projects since then, the main objective of this book is to render a systematic account of questions concerning the microwave radiometry of the Earth’s surface in the presence of vegetation canopies.

Because prevailing atmospheric/troposcopic conditions greatly influence radio wave propagation above 10 GHz, the unguided propagation of microwaves in the neutral atmosphere can directly impact many vital applications in science and engineering. These include transmission of intelligence, and radar and radiometric applications used to probe the atmosphere, among others. Where most books address either one or the other, Microwave Propagation and Remote Sensing: Atmospheric Influences with Models and Applications melds coverage of these two subjects to help readers develop solutions to the problems they present. This reference offers a brief, elementary account of microwave propagation through the atmosphere and discusses radiometric applications in the microwave band used to characterize and model atmospheric constituents, which is also known as remote sensing. Summarizing the latest research results in the field, as well as radiometric models and measurement methods, this book covers topics including: Free space propagation Reflection, interference, polarization, and other key aspects of electromagnetic wave propagation Radio refraction and its effects on propagation delay Methodology of estimating water vapor attenuation using radiosonde data Knowledge of rain structures and use of climatological patterns to estimate/measure attenuation of rain, snow, fog, and other prevalent atmospheric particles and human-made substances Dual/multifrequency methodology to deal with the influence of clouds on radiometric attenuation Deployment of microwaves to ascertain various tropospheric conditions Composition and characteristics of the troposphere, to help readers fully understand microwave propagation Derived parameters of water, free space propagation, and conditions and variable constituents such as water vapor and vapor pressure, density, and ray bending

This book contains a selection of refereed papers presented at the 6 Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment held in Florence, Italy on March 15-18, 1999. Over the last two decades, passive microwave remote sensing has made considerable progress, and has achieved significant results in the study of the Earth's surface and atmosphere. Many years of observations with ground-based and satellite-borne sensors have made an important contribution to improving our knowledge of many geophysical processes of the Earth's environment and of global changes. The evolution in microwave radiometers aboard satellites has increased steadily over recent years. At the same time, many investigations have been carried out both to improve the algorithms for the retrieval of geophysical parameters and to develop new technologies. The book is divided into four main sections: three of these are devoted to the observation of the Earth's surface and atmosphere, and the fourth, to future missions and new technologies. The first section deals with the study of sea and land surfaces, and reports recent advances in remote sensing of ocean wind, sea ice, soil moisture and vegetation biomass, including electromagnetic modelling and the assimilation of radiometric data in models of land surface processes. The following two sections are devoted to the measurement of atmospheric quantities which are of fundamental importance in climatology and meteorology, and, since they influence radio-wave propagation, they also impact on several other fields, including geodesy, navigational satellite and radioastronomy. The last section presents an overview of new technologies and plans for future missions.

At the beginning of the 21st century the world still faces various global environmental issues. Examples include the rise in atmosperic temperature due to the increase of atmosperic carbon dioxide, the depletion of the ozone layer and El Nino related climatic anomalies. Remote sensing technologies that use electromagnetic waves are quite useful in measuring physical parameters which describe global environments. This book covers the theory of electromagnetic remote sensing and the basic technologies used.
