The book "Earth Gravity Field from Space - from Sensors to Earth Sciences" is a specialized work that deals with the determination of the Earth's gravity field. It is based on the results of a workshop organized by the International Space Science Institute (ISSI), which took place from March 11 to 15, 2002, in Bern. The aim of the workshop was to bring together active researchers from various disciplines such as satellite geodesy, gravity field modeling, solid-state physics, and oceanography to discuss the exciting new developments made possible by current and upcoming space missions. The structure of the workshop included several plenary sessions with introductory lectures and extensive discussion opportunities to formulate insights and future goals. The editors G. Beutler, M. R. Drinkwater, and R. Rummel have carefully compiled the content to provide a comprehensive overview of the advancements in research on the Earth's gravity field.
