Book Description
Integrating decades of research conducted by leading scientists in the field, Remote Sensing of Energy Fluxes and Soil Moisture Content provides an overview of state-of-the-art methods and modeling techniques employed for deriving spatio-temporal estimates of energy fluxes and soil surface moisture from remote sensing. It also underscores the range of such techniques available nowadays as well as the operationally distributed networks that provide today in-situ validated relevant observations. The book brings together three types of articles: Comprehensive reviews that examine the developments in concepts, methods, and techniques employed in deriving land surface heat fluxes as well as soil surface moisture on field, regional, and large scales, paying particular emphasis to the techniques exploiting Earth Observation (EO) technology Detailed insights into the principles and operation of the most widely applied approaches for the quantification and analysis of surface fluxes and soil moisture with case studies that directly show the great applicability of remote sensing in this field, or articles discussing specific issues in the retrievals of those parameters from space Focused articles integrating current knowledge and scientific understanding in the remote sensing of energy fluxes and soil moisture, that are highlighting the main issues, challenges, and future prospects of this emerging technology. Designed with different users in mind, the book is organized in four more or less independent units that make specific information easy to find. It presents a discussion on the future trends and prospects, underlying the scientific challenges that need to be addressed adequately in order to derive more accurate estimates of those parameters from space.

Book Description
The HAPEX-MOBILHY regional experiment provided an significant opportunity to analyze the partition of energy and distribution of water over land surfaces. The combination of remotely sensed data and ground instrument networks over the large-scale in situ experiment allowed investigation of spatial and temporal variation of such hydrologic parameters as the latent heat flux and surface soil moisture. A literature review provided the fundamental physical theory for remote sensing detection of surface energy balance components and surface soil moisture. In instances where ground-based instruments were incorporated into the remote sensing approach, or were specifically of interest in the study, the appropriate theoretical background was also presented. The review identifies the approaches necessary for future attempts to model evaporative flux directly with combined remote-based and ground-based data collection systems. Sensors and equipment used in the HAPEX-MOBILHY Program to monitor land surface hydrologic processes are identified and described. Algorithms were developed for use in computer processing of data collected by a passive microwave sensor, the Push Broom Microwave Radiometer. The variation of the surface energy balance was examined through the use of the evaporative fraction, a ratio found to be relatively stable for daylight periods. The behavior of the evaporative fraction was examined with respect to location and meteorological conditions to determine its suitability for remote sensing applications. Surface soil moisture variation was examined for two intensely instrumented ground sites in the HAPEX-MOBILHY experiment grid using passive microwave remote sensing. The relationship between passive microwave measurements and ground truth data was examined to attempt to calibrate the remote sensor. Factors which resulted in a weak relationship were examined. The association between surface energy balance and soil moisture was examined using several soil moisture measurement techniques. This resulted in an understanding of the limitations of passive microwave remote sensing for use in measuring a state variable, moisture, as it pertains to evaporative flux estimation by remote-sensing techniques. Several suggestions for additional research priorities in this field were made with future large-scale in situ experiments in mind. Opportunities to combine these research efforts with ongoing or planned projects are noted.

Book Description
Sealing up in Hydrology using Remote Sensing Edited by J. B. Stewart Institute of Hydrology, UK E. T. Engman NASA Goddard Space Flight Center, USA R. A. Feddes Wageningen Agricultural University, The Netherlands Y. Kerr Centre d’Etudes Spatiales de la Biosphere, France The most pressing modern environmental problems are considered to affect the entire globe. For example, climate change, deforestation and desertification are all happening on such a large scale that they may affect the sustainability of man’s future. What is needed to address this question quantitatively are more reliable data on large scale land use and land-use change, and their impacts on water resources and climate. The catch is that we are never going to be able to measure directly key hydrological and meteorological variables at enough points on the ground to give adequate description of the large areas (regions and continents) for which information is required. The only way to get this is via large scale modelling and the development of remote sensing techniques. This book brings together the presentations made at a recent workshop by experts, who met to consider the problems of scaling up from local to global spatial scales and from the instantaneous satellite measurements to daily or longer time scales. The authors’ collective views represent the state of the art of their science as seen by an active international remote sensing community, and ground and planetary-based measurement scientists and modellers.

Book Description
Although remote sensing is recognized as a powerful tool, less attention has been given in the past to the use of thermal, and especially thermal infrared (TIR) remote sensing. TIR data is useful for understanding the fluxes and redistribution of materials as a key aspect of land surface processes and land-atmosphere inter-relationships. This book

Book Description
The continental hydrological cycle is one of the least understood components of the climate system. The understanding of the different processes involved is important in the fields of hydrology and meteorology.In this volume the main applications for continental hydrology are presented, including the characterization of the states of continental surfaces (water state, snow cover, etc.) using active and passive remote sensing, monitoring the Antarctic ice sheet and land water surface heights using radar altimetry, the characterization of redistributions of water masses using the GRACE mission, the potential of GNSS-R technology in hydrology, and remote sensing data assimilation in hydrological models.This book, part of a set of six volumes, has been produced by scientists who are internationally renowned in their fields. It is addressed to students (engineers, Masters, PhD) , engineers and scientists, specialists in remote sensing applied to hydrology. Through this pedagogical work, the authors contribute to breaking down the barriers that hinder the use of Earth observation data. Provides clear and concise descriptions of modern remote sensing methods Explores the most current remote sensing techniques with physical aspects of the measurement (theory) and their applications Provides chapters on physical principles, measurement, and data processing for each technique described Describes optical remote sensing technology, including a description of acquisition systems and measurement corrections to be made

Book Description
Generating a satisfactory classification image from remote sensing data is not a straightforward task. Many factors contribute to this difficulty including the characteristics of a study area, availability of suitable remote sensing data, ancillary and ground reference data, proper use of variables and classification algorithms, and the analyst's e
