Book Description
Accurate accounting of surface emissivity is essential for the retrievals of surface temperature from remote sensing measurements, and for the computations of longwave (LW) radiation budget of the Earth's surface. Past studies of the above topics assumed that emissivity for all surface types, and across the entire LW spectrum is equal to unity. There is strong evidence, however, that emissivity of many surface materials is significantly lower than unity, and varies considerably across the LW spectrum. We have developed global maps of surface emissivity for the broadband LW region, the thermal infrared window region (8-12 micron), and 12 narrow LW spectral bands. The 17 surface types defined by the International Geosphere Biosphere Programme (IGBP) were adopted as such, and an additional (18th) surface type was introduced to represent tundra-like surfaces. Laboratory measurements of spectral reflectances of 10 different surface materials were converted to corresponding emissivities. The 10 surface materials were then associated with 18 surface types. Emissivities for the 18 surface types were first computed for each of the 12 narrow spectral bands. Emissivities for the broadband and the window region were then constituted from the spectral band values by weighting them with Planck function energy distribution.Wilber, Anne C. and Kratz, David P. and Gupta, Shashi K.Langley Research CenterSURFACE TEMPERATURE; TEMPERATURE SENSORS; SURFACE PROPERTIES; COMPUTATION; LONG WAVE RADIATION; ATMOSPHERIC RADIATION; TUNDRA; SPECTRAL REFLECTANCE; SPECTRAL BANDS; LITHOSPHERE; INFRARED WINDOWS; ENERGY BUDGETS; EMISSIVITY; BROADBAND; BIOSPHERE

Book Description
Water Scarcity, Contamination, and Management presents new and updated material, including case studies, step-by-step guidance on key procedures and protocols, and timely topics such as climate change and integrated water resource management. This book is divided into three key sections. Section 1—Water Resource Scarcity—focuses on sustainable development and management of water resources and techniques and methods for improving water use efficiency. Section 2—Contamination of Water Resources—focuses on understanding the quality of water resources, migration of pollutant sources, geochemical processes, groundwater depletion, and seasonal variations in contaminant concentration, water resources’ quality status, and associated human health risks. Section 3—Water Resource Management—considers a consolidated and coordinated approach to find the solution to water resource issues. Presenting a comprehensive overview of the water management field, the book serves as a valuable reference for students, professors, scholars, researchers, and consultants in the fields of water resources, civil engineering, environmental science and engineering, and hydrology. Provides an overview of the current status of water resources utilization, the likely scenario of future demands, and the advantages and disadvantages of systems techniques Includes numerous examples and real-world case studies Presents the roles of remote sensing and GIS in solving the water resource crisis

Book Description
Comprehensive Remote Sensing, Nine Volume Set covers all aspects of the topic, with each volume edited by well-known scientists and contributed to by frontier researchers. It is a comprehensive resource that will benefit both students and researchers who want to further their understanding in this discipline. The field of remote sensing has quadrupled in size in the past two decades, and increasingly draws in individuals working in a diverse set of disciplines ranging from geographers, oceanographers, and meteorologists, to physicists and computer scientists. Researchers from a variety of backgrounds are now accessing remote sensing data, creating an urgent need for a one-stop reference work that can comprehensively document the development of remote sensing, from the basic principles, modeling and practical algorithms, to various applications. Fully comprehensive coverage of this rapidly growing discipline, giving readers a detailed overview of all aspects of Remote Sensing principles and applications Contains ‘Layered content’, with each article beginning with the basics and then moving on to more complex concepts Ideal for advanced undergraduates and academic researchers Includes case studies that illustrate the practical application of remote sensing principles, further enhancing understanding
