This PhD thesis and the underlying research would not have been possible without the help of many people. First and foremost I want to thank my supervisor and promotor, Prof. Roland Klees, for his help and guidance during the five years of research. He was always available regardless of his busy schedule, and managed to keep me on track while giving me the freedom to pursue my own ideas. Valuable input came from the other scientific staff members, Pavel Ditmar, Jürgen Kusche, Brian Gunter, and David Lavalle. Invaluable help was provided by the "global GRACE people", Xianglin Liu and Christian Siemes, who also shared a room with me and were always good company. Other colleagues contributed, too: Cornelis Slobbe, Bas Alberts, Jasper van Loon, Elena Revtova, Riccardo Riva, and Mark-Willem Jansen. Ward Stolk did important work on mass balance estimates for Greenland and Antarctica in the course of his MSc thesis. Administrative tasks were handled admirably by our management assistants Relly van Wingaarden, Miranda van Haagen, and Fiona Tuynman. ICESat data has kindly been provided by Dr. Tim Urban of the CSR. The PCR-GLOBWB hydrological model was used courtesy of Rens van Beek and Marc Bierkens at the University of Utrecht. Computing time on the national supercomputers Teras, Aster, and Huygens was provided by Stichting Nationale Computer Faciliteiten (NCF) under grant
