Leeds Dynamo Simulations for Analysis of Rapid Geomagnetic Field Changes

A series of Leeds dynamo simulations used to analyze rapid changes in the Earth's magnetic field. The dataset includes configuration files, executable scripts, and parameter logs that allow for the reproduction of simulations run on high-performance computing systems. It was produced by the British Geological Survey (BGS) and last updated on 2026-05-28.

Use Cases

• Reproducing dynamo simulations based on provided configuration files and scripts.
• Analyzing simulated magnetic field features for dynamical and morphological agreement with observed fields.
• Investigating rapid changes in field intensity and direction using thermally-driven and thermochemically-driven cases.

Strengths

• Includes configuration files and executable scripts for reproducing simulations.
• Parameter details for each simulation are documented in a spreadsheet ('SimulationsLog').
• All simulations have a defined Prandtl number (Pr=1).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
