Global spherical harmonic models of the internal magnetic field of the Moon based on sequential and coestimation approaches: Models, grids, and manuscript

based on a paper of the same name published in JGR-Planets by Purucker and Nicholas, 115, E12007, doi:10.1029/2010JE003650

The sequential model is based on the internal field (BrI,BtI,BpI) from wake (sun=1) and tail (GSE from 160 to 200) times. It can be downloaded here.

Note: The lunar magnetic field models here have been evaluated at 30 km altitude to spherical harmonic degree 170. The full-wavelength resolution of the model is about 64 km at low and mid-latitudes.
