GGOS 2020 Acknowledgments

This work has been supported by many colleagues in geodesy and various fields of Earth science. The Editors are grateful to the many authors of the chapter writing teams, and in particular the chapter lead authors for their contributions.

The book has gone through several rounds of reviews. Individual reviews of an early draft were provided by Chris Hughes, Norman Miller, Ivan Mueller, Chris Reigber, Fernando Sanos, and Christian Tscherning. An open review in the IAG community resulted in more than 300 individual comments. A final review of parts of the book was carried out by an IAG Panel consisting of Hermann Drewes, Chris Rizos, and Michael Sideris. The Editors extend their sincere thanks to all who invested time and effort into turning this book into a valuable basis for the further development of GGOS.

Financial support for the Lead Editor was provided by National Aeronautics and Space Administration (through a contract with the Jet Propulsion Laboratory and in the frame of several research projects), and the Norwegian Mapping Authority.

Parts of the work described in this document were carried out at the Jet Propulsion Laboratory, California Institute of Technology, under contracts with the National Aeronautics and Space Administration.
