Abstract

As part of the GOCE User Toolbox Specification project (GUTS), the GUTS team will carry out a scientific trade-off study, to select the best algorithms to fulfil the user requirements for the toolbox. In some cases the selection is straightforward. However, in other cases, the choice will depend on scientific applications as well as the algorithm efficiency and more practical considerations. Studies need to be performed to demonstrate the best possible algorithm. Examples include the selection of filtering functions and the choice of interpolation schemes used in calculation of a mean dynamic topography from combined GOCE and satellite altimeter data. The trade-off study will also select the functionality of the toolbox, given the user requirements and the recommended algorithms. In this poster we will present the expected functionality of the toolbox, and the most important algorithm selections. As part of the scientific trade-off, a pilot application is investigating validation of mean dynamic topography, generated from pseudo observations using proposed toolbox algorithms, against ocean model data. The study will also include results from research into methods of calculation of mean dynamic topography and filtering methods presented at this workshop.
