Book Description
R.E. Newell President, International Commission on Climate International Association of Meteorology and Atmospheric Physics Water is the active ingredient in the global climatic system, its physical properties ensuring that it plays a major role. Its high thermal capacity provides a mechanism for moderating mid latitude winter temperatures; solar energy is absorbed by the surface layers of the middle latitude oceans in summer and is released to the atmosphere in winter as the ocean cools. The variation of saturation vapour pressure with temperature is the factor which causes oceanic surface temperatures at low latitudes to be limited by evaporation to values near 29°C, thereby limiting tropical marine air temperatures to about the same value. The substantial amount of energy involved in phase changes - the latent heat - governs the passage of solar energy to the atmo sphere; visible solar radiation is absorbed at the Earth's surface, energy is supplied to evaporate water and the latent heat is released to the atmosphere when and where condensation occurs, which is often a considerable distance from the source of the moisture. The infrared radiative characteristics of water vapour, namely the broad vibration-rotation bands typical of a triatomic molecule, permit it to act as the principal agent of energy loss from the atmosphere, throu?,h infrared radiation to space.

Book Description
We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space (National Academies Press, 2018) provides detailed guidance on how relevant federal agencies can ensure that the United States receives the maximum benefit from its investments in Earth observations from space, while operating within realistic cost constraints. This short booklet, designed to be accessible to the general public, provides a summary of the key ideas and recommendations from the full decadal survey report.

Book Description
Natural and human-induced changes in Earth's interior, land surface, biosphere, atmosphere, and oceans affect all aspects of life. Understanding these changes requires a range of observations acquired from land-, sea-, air-, and space-based platforms. To assist NASA, NOAA, and USGS in developing these tools, the NRC was asked to carry out a "decadal strategy" survey of Earth science and applications from space that would develop the key scientific questions on which to focus Earth and environmental observations in the period 2005-2015 and beyond, and present a prioritized list of space programs, missions, and supporting activities to address these questions. This report presents a vision for the Earth science program; an analysis of the existing Earth Observing System and recommendations to help restore its capabilities; an assessment of and recommendations for new observations and missions for the next decade; an examination of and recommendations for effective application of those observations; and an analysis of how best to sustain that observation and applications system.

Book Description
Hydrology and Global Environmental Change presents the hydrological contribution to, and consequences of, global environmental change. Assuming little or no prior knowledge on the part of the reader, the book looks at the main processes of global environmental change - global scale processes, large regional processes, repetitive processes - and how the hydrological cycle, processes and regimes impact on GEC and vice-versa.

Book Description
Water is an extremely important factor in global environmental change. Water influences the processes causing change. The human and economic consequences of changes in the water system can be very significant. The aim of this NATO Advanced Study Institute was to present a state-of-the-art assessment of the role of water in global change, ranging from a consideration of atmospheric processes to the social and political impacts of changes in water resources. Many initiatives have recently been developed, such as international conferences and research programmes in particular themes, but there was still a need for information from these diverse activities to be brought together. One of the aims of the ASI was to encourage cross-fertilization between the various disciplines looking at water in the global system. This book contains the expanded written versions of the lectures presented during the AS! held in Italy in May/June 1994. It falls into two basic parts. The first twelve chapters cover the role of water in the climate system and climate modelling. Various areas of the water balance including global budgets, the effect of each element of the water balance on regional and global climates, and procedures used to model hydrological processes at all scales are discussed. Precipitation, ice, lake, groundwater, land surface and atmospheric considerations are included together with hydrological process linkage to climate models. Ocean effects were not covered as they were considered to be outside the scope of this particular AS!.

Book Description
The Hydrological Cycle theme is a component of Encyclopedia of Water Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty Encyclopedias. The Hydrological Cycle is a process of constant water exchange or water circulation in the hydrosphere, i.e. in the system of the atmosphere - Earth's surface – soil cover - upper lithosphere (to a depth of 2000 m). Water in the hydrosphere is liquid, solid or gaseous; during the hydrological cycle it moves under the effect of heat energy, gravitation and capillary forces, converting from a liquid to its solid state or gas, and back. The hydrological cycle is one of the major geophysical processes on the planet providing relative stability of natural conditions and continuous distribution of water between ocean, land and atmosphere. The content of the Theme on The Hydrological Cycle is organized with state-of-the-art presentations covering several topics: Exchanges of Water in the Hydrosphere; Hydrosphere Components; World Water Balance; evaporation; Precipitation; Surface Water Runoff; Groundwater Hydrogeology; Glaciers and Their Significance for the Earth Nature, which are then expanded into multiple subtopics, each as a chapter. These four volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, Managers, and Decision makers and NGOs
