The GOCE User Toolbox GUT is a compilation of tools for the utilisation and analysis of GOCE Level 2 products. GUT support applications in Geodesy, Oceanography and Solid Earth Physics. GUT consists of a series of advanced computer routines that carry out the required computations. Recently, the second version of the GOCE User Toolbox (GUT) was developed to enhance the exploitation of GOCE level 2 data with ERS‐ENVISAT altimetry. The developments of GUT focused on the following issues: Data Extraction, Generation, Filtering, and Data Save and Restore. Without any doubt the development of the GOCE user toolbox have played a major role in paving the way to successful use of the GOCE data for oceanography. The objective of the ongoing GUT project is to further develop GUT by implementing functionalities that have been requested by the general science community. Accordingly, the GUT version 3 will have:

An attractive and easy to use Graphic User Interface (GUI) for the toolbox,

Further software functionalities such as handling of GOCE gradients, anisotropic diffusive filtering and computation of Bouguer and isostatic gravity anomalies.

An associated GUT VCM tool for analyzing the GOCE variance covariance matrices.
Also, in this project an independent validation of GOCE Level-2 Gravity Field Models including their error covariance matrices will be carried out. Side activities are the toolbox maintenance, user support and toolbox outreach and promotion.
