cra:holocene-vadm-composite-18ka159 records5 columnsv1.0 · issued 2026-07-21
01Description
A composite series of Earth's virtual axial dipole moment from the Late Glacial to the present, assembled from the published paleomagnetic reconstructions (GLOPIS-75, GEOMAGIA50-class compilations, CALS10k.2, and the gufm1/IGRF era for the recent centuries), with the uncertainty envelope and the contributing source named per epoch. This is the series behind the observed-record dipole figure on the Association's site.
