Abstract. pygeodyn is a sequential geomagnetic data assimilation package written in Python. It gives access to the core surface dynamics, controlled by geomagnetic observations, by means of a stochastic model anchored to geodynamo simulation statistics. pygeodyn aims at giving access to a user-friendly and flexible data assimilation algorithm. It is designed to be tunable by the community by different means: possibility to use embedded data and priors, or to supply custom ones; tunable parameters through configuration files; adapted documentation for several user profiles. In addition, output files are directly supported by the package webgeodyn that provides a set of visualisation tools to explore the results of computations.

Short summary
pygeodyn is a geomagnetic data assimilation package written in Python. It gives access to the Earth's core flow dynamics, controlled by geomagnetic observations, by means of a reduced numerical model anchored to geodynamo simulation statistics. pygeodyn aims at providing the community with a user-friendly and tunable data assimilation algorithm. It can be used for education, geomagnetic model production or tests in conjunction with webgeodyn, a set of visualisation tools for geomagnetic models.
