دانلود کتاب Four-Dimensional Model Assimilation of Data: A Strategy for the Earth System Sciences

Panel on Model-Assimilated Data Sets for Atmospheric and Oceanic Research, Environment and Resources Commission on Geosciences, Division on Earth and Life Studies, National Research CouncilThis volume explores and evaluates the development, multiple applications, and usefulness of four-dimensional (space and time) model assimilations of data in the atmospheric and oceanographic sciences and projects their applicability to the earth sciences as a whole.Using the predictive power of geophysical laws incorporated in the general circulation model to produce a background field for comparison with incoming raw observations, the model assimilation process synthesizes diverse, temporarily inconsistent, and spatially incomplete observations from worldwide land, sea, and space data acquisition systems into a coherent representation of an evolving earth system.The book concludes that this subdiscipline is fundamental to the geophysical sciences and presents a basic strategy to extend the application of this subdiscipline to the earth sciences as a whole.
