SwarmDF: A toolbox for analysing high-latitude ionospheric electrodynamics

The Swarm Data Fusion (SwarmDF) toolbox is designed as an easy-to-use Python module for analysing the local electrodynamics of the high-latitude ionosphere by combining measurements from ESA’s Swarm satellites with additional ionospheric and thermospheric datasets. Given a Swarm satellite ID, a regional grid, and a time interval, the toolbox automatically retrieves and combines available observations from SuperDARN, SuperMAG, Iridium/AMPERE, and Swarm electromagnetic field measurements. SwarmDF uses the local mapping of polar ionospheric electrodynamics (Lompe) technique to reconstruct two-dimensional maps of key electrodynamic parameters in the vicinity of the Swarm satellite tracks. To assess and quantify reconstruction performance, SwarmDF integrates the LompeOSSE Python module, which generates controlled synthetic electrodynamics datasets based on Gamera simulations and enables systematic comparisons with the toolbox outputs under different data availability and configuration scenarios. Featuring a user-friendly graphical interface, SwarmDF simplifies data handling and model setup for high-latitude ionospheric electrodynamic studies using Swarm observations.
