Micromagnetic Simulations of Magnetite Grains for Magnetic Signal Mapping

A 2022 dataset by David Cortés-Ortuño, Karl Fabian, and Lennart V. de Groot from Utrecht University contains simulation outputs and analysis scripts for mapping magnetic signals. The dataset includes MERRILL simulation scripts, output files, Jupyter notebooks for analysis, and pre-computed data files to calculate inversions and produce figures. It supports the associated preprint published in the Earth and Space Science Open Archive.

Use Cases

• Validating micromagnetic models based on MERRILL simulation outputs mentioned in the description
• Reproducing figures and inversion analyses from the associated publication using the provided Jupyter notebooks
• Comparing internal magnetic configurations of magnetite grains based on the pre-computed inversion data files

Strengths

• Includes scripts and output files from MERRILL simulations, enabling reproducibility
• Contains pre-computed data files to calculate inversions without processing raw vbox files
• Accompanied by a detailed README file in markdown format providing full simulation details

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Last update date is unknown; freshness unverified
