The main goal of the study is to obtain a consistent height and depth reference system in the form of a geoid for the Dutch mainland and marine area. For this purpose a procedure has been developed and tested to combine available gravity data and external data from satellite altimetry, GPS and levelling in an optimal manner. After all, local gravimetric(More)
The European Space Agency released a call for the next Earth Explorer Core Mission Ideas in March 2005, with the aim to select a 7th Earth Explorer mission to be launched in the next decade. Twenty-four proposals were received and subject to detailed scientific and technical assessment. In the so-called Phase 0, six concepts were selected and further(More)

The Soil Moisture and Ocean Salinity (SMOS) mission will provide L-Band multi-angular measurements of the surface emission with a 2-D interferometric radiometer on a global basis [1]. Soil moisture will be retrieved from collected and simulated data using a minimization algorithm. The success of the process will partly depend on how accurate is the(More)
The Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite aimed at determining the Earth's mean gravity field. GOCE delivered gravity gradients containing directional information, which are complicated to use because of their error characteristics and because they are given in a rotating instrument frame indirectly related to the Earth.(More)
We explore how GOCE gravity gradient data can improve modeling of the Earth's lithosphere and thereby contribute to a better understanding of the Earth's dynamic processes. We study the use of gravity gradient grids to provide improved information about the lithosphere and upper mantle in the well-surveyed NorthEast Atlantic Margin. In particular, we(More)
