The 2014 Division Outstanding Young Scientists Award is awarded to Roelof Rietbroek for providing methodological solutions to the problem of integrating GRACE data, together with GPS, altimetry, and model data into estimates of mass redistribution.

Roelof Rietbroek has contributed several important geodetic methodological developments that relate to the problem of integrating GRACE (the Gravity Recovery and Climate Experiment), GPS, altimetry, and models into estimates of mass redistribution. Mass redistribution is an important topic in modern geodesy and Rietbroek’s methods account for effects such as loading, self-gravitation, the Earth’s rotation and the reference frame. He has worked out the formalism for consistent fingerprint inversion for present-day sea level change from gravimetry and altimetry data. These early career achievements have already had a significant impact on geodesy and on the future of geodetic Earth system research. Rietbroek’s work has generated a number of new insights concerning the understanding of the ocean from geodesy including validating GRACE with ocean bottom pressure sensors, improved understanding of sea level change and ocean mass change at sub-monthly time scales, and the dynamic effects of melting ice-sheets. His work has also yielded insight into the first geodetic estimate of secular motion. These extensive achievements highlight that Rietbroek truly is an outstanding young scientist.
