A Lunar–Solar Declination Gate in the Transfer of Solar-Wind Coupling to Low–Mid-Latitude Ground Magnetic Variability

This archive contains the reproducible package for A Lunar–Solar Declination Gate in the Transfer of Solar-Wind Coupling to Low–Mid-Latitude Ground Magnetic Variability. This study tests where a previously reported lunar-declination gate acts in the Sun–magnetosphere–ionosphere–ground chain. Using two independent thirteen-station INTERMAGNET panels from 2011–2024, the analysis confirms the gate in night-sector ground-vector rate-of-change outcomes and localizes it to the transfer of sustained solar-wind coupling into the low–mid-latitude ground vector. The archive includes the analysis code, locked station lists, derived daily analysis tables, parsed OMNI coupling table, result tables, and figures needed to reproduce the main numerical claims. Raw INTERMAGNET and SuperMAG one-minute data are not redistributed; derived station-day tables and retrieval scripts are provided under the data providers’ terms. This record is a companion/follow-up archive to the prior Zenodo record 10.5281/zenodo.20734177 for Paper1, which reported the original F10.7-conditioned lunar-declination gate. The present record extends that work by testing where the gate acts in the Sun–magnetosphere–ionosphere–ground chain and by localizing it to the solar-wind-coupling-to-ground transfer step.
