[en] The EU-funded project SANGOMA – Stochastic Assimilation of the Next Gener-
ation Ocean Model Applications –provides new developments in data assimilation to ensure
that future operational systems can make use of state-of-the-art data-assimilation methods
and related analysis tools. One task of SANGOMA is to develop a collection of common
tools for data assimilation with a uniform interface so that the tools are usable from dif-
ferent data assimilation systems. The tool developments mainly aim at tools that support
ensemble-based data assimilation applications like for the generation of perturbations, to
perform transformations, to compute diagnostics, as well as further utilities. In addition, a
selection of ensemble filter analysis steps is included. The tools are implemented in Fortran
and as scripts for Matlab or Octave. They are provided as free open-source programs via the
project web site [http://www.data-assimilation.net]. This contribution provides an overview
of the tools that are available in the latest release V1 of the SANGOMA tools as well as the
plans for the next release.
