Gravity Inversion and Integration

Theory and Applications in Geodesy and Geophysics

• Broschiertes Buch

Produktbeschreibung

This book contains theory and applications of gravity both for physical geodesy and geophysics. It identifies classical and modern topics for studying the Earth. Worked-out examples illustrate basic but important concepts of the Earth's gravity field. In addition, coverage details the Geodetic Reference System 1980, a versatile tool in most applications of gravity data.
The authors first introduce the necessary mathematics. They then review classic physical geodesy, including its integral formulas, height systems and their determinations. The next chapter presents modern physical geodesy starting with the original concepts of M.S. Molodensky. A major part of this chapter is a variety of modifying Stokes' formula for geoid computation by combining terrestrial gravity data and an Earth Gravitational Model.
Coverage continues with a discussion that compares today's methods for modifying Stokes' formulas for geoid and quasigeoid determination, a description of several modern tools in physical geodesy, and a review of methods for gravity inversion as well as analyses for temporal changes of the gravity field.
This book aims to broaden the view of scientists and students in geodesy and geophysics. With a focus on theory, it provides basic and some in-depth knowledge about the field from a geodesist's perspective.

Autorenporträt

Lars E. Sjöberg has been a professor of Geodesy at Sweden¿s Royal Institute of Technology (KTH) for 30 years and has been the chair of 4 IAG Special Study Groups on gravity and geodynamics. He has been the Editor-in-Chief of the Journal of Geodetic Science since it was founded in 2011. He developed the unique KTH method with additive corrections using least squares by spectral weighting of observables, as well as a method for estimating Moho depth and density contrast from gravity. He leads several international geoid schools on the KTH method, and has published more than 330 articles, mostly in peer-reviewed journals. Mohammad Bagherbandi is senior researcher at the Royal Institute of Technology (KTH) and a Professor at the University of Gävle, Sweden. His professional interests include Physical Geodesy, Geodynamics and Satellite Gravimetry. He received his Ph.D. in Geodesy from the KTH in 2011, and became an instructor at the Institute in 2013. His background is in Land Surveying Engineering, and he completed a Master of Science in Geodesy in Iran. He is currently pursuing multidisciplinary research combining directions such as Geophysics, Geodesy and Land Surveying (applied geodesy). His main research interest is in developing and interconnecting Geodesy and Geophysics.
