Overview

ChaosMagPy is a simple Python package for evaluating the CHAOS geomagnetic field model and other models of Earth’s magnetic field. The latest CHAOS model is available at http://www.spacecenter.dk/files/magnetic-models/CHAOS-7/. To quickly get started, download the complete working example including the latest model under the “Forward code” section.
