The GOCE User Toolbox (GUT) is a compilation of tools for the utilisation and analysis of GOCE products. GUT supports applications in Geodesy, Oceanography and Solid Earth Physics.
The current version of GUT is 3.2.
GUT is a command-line processor that has been designed for users at all levels of expertise.
The first level is the use of pre-built workflows allowing the computation of geoid/gravity field/mean dynamic topography in one single step, with very few inputs required. You can also generate your own workflows for enhanced or specialised processing. GUT generates all output files in netCDF format in compliance with the CF-Conventions, and gridded results may be visualised using the BratDisplay tool from ESA's Basic Radar Altimetry Toolbox.
GUT is fully open source software under GNU GPL license. Advanced users can easily extend the toolbox in accordance with the workflow-based processing design principles, and contribute these enhancements to the GUT user community. The GUT API can also be used to develop independent applications, taking advantage of the algorithmic and input/output facilities used by the command-line processor.
Applications of the Variance-Covariance Matrix require additional software now included in GUT. The additional software has been developed by Georges Balmino, enhanced by Rory Bingham and Bruno Lucas and made available to the scientific community. This application requires heavy computational resources. In the current version of GUT documentation and tutorial, they are not fully supported. A short description of the Variance-Covariance Matrix Tool and examples of applications is available in the user guide.
