Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 68. Human activities in the polar regions have undergone incredible changes in this century. Among these changes is the revolution that satellites have brought about in obtaining information concerning polar geophysical processes. Satellites have flown for about three decades, and the polar regions have been the subject of their routine surveillance for more than half that time. Our observations of polar regions have evolved from happenstance ship sightings and isolated harbor icing records to routine global records obtained by those satellites. Thanks to such abundant data, we now know a great deal about the ice-covered seas, which constitute about 10% of the Earth's surface. This explosion of information about sea ice has fascinated scientists for some 20 years. We are now at a point of transition in sea ice studies; we are concerned less about ice itself and more about its role in the climate system. This change in emphasis has been the prime stimulus for this book.

Book Description
"Techniques for gathering data by remote sensors on satellites utilized for sea ice research are summarized. Measurement of brightness temperatures by a passive microwave imager converted to maps of total sea ice concentration and to the areal fractions covered by first year and multiyear ice are described. Several ancillary observations, especially by means of automatic data buoys and submarines equipped with upward looking sonars, are needed to improve the validation and interpretation of satellite data. The design and performance characteristics of the Navy's Special Sensor Microwave Imager, expected to be in orbit in late 1985, are described. It is recommended that data from that instrument be processed to a form suitable for research applications and archived in a readily accessible form. The sea ice data products required for research purposes are described and recommendations for their archival and distribution to the scientific community are presented."--NTIS abstract.

Book Description
Remote Sensing of Sea Ice in the Northern Sea Route: Studies and Applications initially provides a history of the Northern Sea Route as an important strategic transport route for supporting the northern regions of Russia and cargo transportation between Europe and the Northern Pacific Basin. The authors then describe sea ice conditions in the Eurasian Arctic Seas and, using microwave satellite data, provide a detailed analysis of difficult sea ice conditions. Remote sensing techniques and the basic principles of SAR image formation are described, as well as the major satellite radar systems used for ice studies in the Arctic. The authors take a good look at the use of sensing equipment in experiments, including the ICE WATCH project used for monitoring the Northern Sea Route. The possibilities of using SAR remote sensing for ice navigation in the Northern Sea Route is also detailed, analysing techniques of automatic image processing and interpretation. A study is provided of regional drifting ice, fast ice and river ice in the coastal areas of the Arctic Seas. The book concludes with a review of the practical experience using SAR images for supporting navigation and offshore industrial activity, based on a series of experiments conducted with the Murmansk Shipping Company on board nuclear icebreakers.

Book Description
Passive Microwave Remote Sensing of Oceans Igor V. Cherny and Victor Yu. Raizer In Passive Microwave Remote Sensing of Oceans, the detailed results of more than 20 years of experimental and theoretical investigations in the field of ocean remote sensing, utilising microwave radiometric techniques and multi-frequency aerospace instruments, are presented. Experimental results presented in this book to some extent contradict the traditional view that microwave radiometry and, in particular, millimetre-wave frequencies are not useful for remote sensing of oceans. The authors show that studies of the ocean and atmosphere as a coupled system, and of processes occurring at the ocean surface and in deep water, can be reliably evolved using compact passive radiometric sensors. They further demonstrate that for studies of global, large-scale and local processes in the ocean-atmosphere system, only the combination of microwave and optical techniques will reveal the spatial structure and dynamics of the ocean surface at scales from centimetres to several hundred metres. The text first introduces ocean surface phenomena, discussing the ocean-atmosphere interface, the classification of surface waves, the generation and statistics of wind waves, and wave-breaking and foaming processes. The microwave emission characteristics of the ocean surface are then described, and the influence of wind waves, bubble-foam-spray coverage, oil spills and sea ice are discussed. The instruments and methods used for passive microwave remote sensing of the oceans from both aircraft and from satellites are reviewed. Microwave observations of processes in the ocean-atmosphere system are then described in detail, incorporating a new approach for microwave diagnostics of deep-ocean processes. Examples presented include the Rossby soliton, frontal zone in the Kurosio region, influence of brief showers on the subsurface layer, and interaction of tropical cyclones with the ocean during their origin and subsequent trajectories over the ocean surface. Readership: Undergraduate and postgraduate students studying remote sensing, marine science, oceanography, geography, geophysics, meteorology, climatology, atmospheric physics and environmental science. Professional oceanographers and those interested in oceanographic remote sensing processes and their applications, marine scientists and engineers, environmental scientists, and those studying the ocean-atmosphere system.

Book Description
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.

Book Description
Introduction to Microwave Remote Sensing offers an extensive overview of this versatile and extremely precise technology for technically oriented undergraduates and graduate students. This textbook emphasizes an important shift in conceptualization and directs it toward students with prior knowledge of optical remote sensing: the author dispels any linkage between microwave and optical remote sensing. Instead, he constructs the concept of microwave remote sensing by comparing it to the process of audio perception, explaining the workings of the ear as a metaphor for microwave instrumentation. This volume takes an “application-driven” approach. Instead of describing the technology and then its uses, this textbook justifies the need for measurement then explains how microwave technology addresses this need. Following a brief summary of the field and a history of the use of microwaves, the book explores the physical properties of microwaves and the polarimetric properties of electromagnetic waves. It examines the interaction of microwaves with matter, analyzes passive atmospheric and passive surface measurements, and describes the operation of altimeters and scatterometers. The textbook concludes by explaining how high resolution images are created using radars, and how techniques of interferometry can be applied to both passive and active sensors.
