The Visible Infrared Imager Radiometer Suite (VIIRS) is the next-generation multispectral imaging instrument to fly on US operational, polar-orbiting meteorological satellites. VIIRS will gather data across 22 spectral bands and be used to create products for a variety of applications including weather forecasting and climate change studies. VIIRS consolidates the best features of heritage instruments, including near-constant resolution and nighttime visible imagery. Visible Infrared Imager Radiometer Suite: A New Operational Cloud Imager provides the first comprehensive guide on the design and exploitation of cloud data collected by the VIIRS.
the wave theory foundations of today's radio occultation techniques<br> <br> Forty years ago, the premier radio occultation problem was how to profile the atmosphere and radius of Mars using signals sent by the Mariner 4 spacecraft. Researchers then could rely on ray theory-based techniques for accurate analysis of the thin, uniform Martian atmosphere. Today's radio occultation challenges mostly involve communications platforms-and related data, instrument systems, and applications-in the Earth's own atmosphere. To deal with the density and complexity of this multilayered medium, an analytical framework that goes beyond ray theory is needed.<br> <br> Setting the cutting edge for the field, Radio Occultations Using Earth Satellites: A Wave Theory Treatment develops a purely wave-theoretic approach to occultation analysis. This approach yields more nuanced results than either ray or hybrid (ray/wave) methodologies offer, and proves suitable for the many variables at work in today's problems.<br> <br> This groundbreaking text provides:<br> * An introduction to the general theory of radio occultations<br> * Development of ray theory and scalar diffraction treatments of radio propagation processes<br> * Development of a wave theoretic treatment of the above wave propagation processes<br> * The correspondence between wave and ray theories<br> * A discussion of how to use a wave-theoretic approach to infer the refractive properties of the propagation medium from a time series set of observations of the propagated wave's phase and amplitude<br> <br> A comprehensive resource that clearly defines the latest topics and methodologies, Radio Occultations Using Earth Satellites is a must-have text for engineers, scientists, students, and managers in satellites communications, navigation, deep space and planetary exploration, aerospace, atmospheric science, physics, and engineering.<br> <br> The Deep Space Communications and Navigation Series is authored by scientists and engineers with extensive experience in astronautics, communications, and related fields. It lays the foundation for innovation in the areas of deep space navigation and communications by disseminating state-of-the-art knowledge in key technologies.

This book provides a state-of-the art overview of satellite archaeology and it is an invaluable volume for archaeologists, scientists, and managers interested in using satellite Earth Observation (EO) to improve the traditional approach for archaeological investigation, protection and management of Cultural Heritage.
The recent increasing development of EO techniques and the tremendous advances in Information and Communication Technologies (ICT) have resulted primarily in Cultural Heritage applications. The book focuses on new challenging prospects for the use of EO in archaeology not only for probing the subsurface to unveil sites and artifacts, but also for the management and valorization as well as for the monitoring and preservation of cultural resources. The book provides a first-class understanding of this revolutionary scenario which was unthinkable several years ago.
The book offers: (i) an excellent collection of outstanding articles focusing on satellite data processing, analysis and interpretation for archaeological applications, (ii) impressive case studies, (iii) striking examples of the high potential of the integration of multi-temporal, multi-scale, multi-sensors techniques.
Each chapter is composed as an authoritative contribution to help the reader grasp the value of its content. The authors are renowned experts from the international scientific community.
Audience: This book will be of interest to scientists in remote sensing applied to archeology, geoarcheology, paleo-environment, paleo-climate and cultural heritage.
This comprehensive handbook on the implementation of short course radiotherapy for the treatment of breast cancer is intended as an up-to-date resource for the clinician. The book opens with a series of chapters on underlying principles and diverse relevant topics, including pathologic anatomy of early-stage breast cancer, radiobiology of accelerated breast irradiation, quality assurance and radiation safety, surgical considerations in partial breast irradiation, and impact of oncoplastic surgery on adjuvant radiotherapy. Individual sections are then devoted to hypofractionated whole breast radiotherapy, accelerated partial breast irradiation, and intraoperative radiotherapy. Each section includes details of patient selection, physics, techniques, data, and toxicity. The reader is provided with clear guidance on the appropriate use of accelerated forms of adjuvant radiotherapy for treatment of early-stage breast cancer and on various emerging treatment approaches.
