A Lunar Synodic Modulation of the F10.7–Geomagnetic Transfer Function in INTERMAGNET Observations, 2011–2024

This archive contains the reproducibility package for the manuscript “A Lunar Synodic Modulation of the F10.7–Geomagnetic Transfer Function in INTERMAGNET Observations, 2011–2024.” The package includes the manuscript PDF/DOCX, figure files, analysis scripts, configuration files, processed data products, sample data for a reproducibility smoke test, checksum files, citation metadata, and extended project documentation. The analysis tests whether lunar synodic phase modulates the empirical transfer coefficient between daily 10.7 cm solar radio flux (F10.7) and ground magnetic H-range across 13 INTERMAGNET observatories from 2011–2024. The central manuscript result is that the fitted F10.7–geomagnetic H-range response varies with lunar synodic phase, with weaker response near new moon and stronger response near full moon. The archive also includes validation and robustness materials related to seasonal controls, calendar-month controls, solar-rotation controls, OMNI solar-wind controls, resampling checks, station holdout checks, and exploratory Jupiter-window analyses. The files in the extended documentation folder are provided for transparency and reproducibility. They are not formal journal Supporting Information unless separately submitted as such. Raw third-party source data are not redistributed unless licensing permits; scripts and manifests identify the external data sources used, including INTERMAGNET, NRCan/Penticton F10.7, NASA OMNI, Astropy, and JPL/Horizons resources where applicable.
