CALS7K.2 Model Inclination and Google Earth - polar scale
This kmz file contains one component, inclination, of the global geomagnetic field model, CALS7K.2 (Korte & Constable, 2005). The file contains the model at 50 year intervals covering the last 7000 years, along with a colour scale bar. The colour scale is polar.

It should be noted tha ...
