01Description
The Association's assembled research database: twenty five series aligned to one monthly axis from 1749 to 2026, from sunspot number through geomagnetic indices, the Eskdalemuir field record, Earth rotation, and monthly earthquake and eruption tallies, delivered as CSV beside the full Master Database workbook with sixteen filterable sheets, a computed dashboard, and per-sheet provenance. Empty cells mean no source epochs in that month; nothing is interpolated.
