Res., 117, B10102, doi:10.1029/2012JB009349. Introduction The 3D pdf file contains an interactive representation of the Brothers volcano magnetization model. 1. 2012jb009349-fs01.pdf 3D pdf file with the magnetization model represented by magnetization isosurfaces under the same convention of Fig.8-9. The 3D model can be rotated and zoomed. It is composed by separate layers that can be switched on and off.
