The GOCE User Toolbox: Toward a first prototype

Data from the ESA GOCE mission are of fundamental importance to the oceanographic community since they will finally allow, in conjunction with altimetry, to access the absolute ocean dynamic topography with a centimetric accuracy at spatial scales down to 100 km, whereas for the moment, only the variable part of the sea level, and thus the geostrophic currents, can be inferred from altimetric heights with sufficient accuracy. Despite their importance for oceanographic studies, the processing and analysis of gravity mission data has proven to be complicated to the point that the lack of proper processing software is hampering progress in the use of those data. To facilitate the easy use of GOCE products for oceanographers and to support the needs of specific applications, the development of a user toolbox was identified as an urgent step at the Second International GOCE User Workshop and the GOCE user toolbox study (=GUTS) begun in January 2006 with the objective of producing algorithms and input and output specification for the subsequent generation of a user toolbox. The scope of this paper is to present a synthesis of what has been achieved so far in the framework of the GUT study and in particular to introduce the first toolbox prototype as well as the complementary Tutorial Toolbox Description that can serve first pilot users as an instruction and that can help later software engineers to construct the toolbox subsequently in a user friendly manner.
