Magnetic Field - Secular Variation of the Horizontal Component of the Total Field Intensity for the Epoch 1995.0

Summary

This map layer shows lines of equal annual change (secular variation) in the horizontal component of the total field intensity of the Earth's magnetic field, derived from the International Geomagnetic Reference Field (IGRF) for the epoch 1995.0. Magnetic intensity is the strength of the magnetic field, and is described in terms of a horizontal component and a vertical component. The change in intensity is measured in nanoTeslas per year.
