Global lihospheric magnetizatin model validated and refined using new satellite observations

The first fully consistent physically motivatetd global earth model is compared with Orsted satellite observations. The correspondence between those observations and the model suggests that it is a good description of first-order magnetic features. We illustrate how the model can be modified to better fit the observations.

Interpretation of the map over North America suggests that the large total field anomaly centered over Kentucky defines the southeast edge of a cold thick magnetic slab rather than representing an area of enhanced magnetization as in previous models.
