Magnetic fields in near-Earth and near-Mars space

The Earth's magnetic field is composed of contributions from many sources. An interactive web page provides the user with an evaluation of many of these magnetic fields. The user can explore that part of the quiet-time earth system that extends from the surface to about 2000 km altitude. Published papers and source code are also available here. We invite your comments and suggestions on this effort. Correspondence should be directed to Terence Sabaka at sabaka@geomag.gsfc.nasa.gov The most recent publication associated with this effort is: Extending Comprehensive Models of the Earth's magnetic field with Oersted and CHAMP data, (Note: This file is 10 Mb in size). Authors: T. Sabaka, N. Olsen, and M. Purucker, Geophysical Journal International, 159, 521-547, Nov 2004, doi: 10.1111/j.1365-246X.2004.02421.x.
The dominant magnetic field source at Mars is from its crust, and the dynamics of this system are dominated by the interaction of the sun's magnetic field with the crustal field. A discrete model provides the user with an evaluation of the crustal magnetic field. Comments and suggestions on this effort should be directed to Benoit Langlais of the University of Nantes or Michael Purucker. The most recent publications associated with this effort are: Crustal magnetic field of Mars, Authors: B. Langlais, M. Purucker, and M. Mandea, Journal of Geophysical Research-Planets, 109, E02008, doi:10.1029/2003JE002048, February, 2004 and A spatially continuous magnetization model for Mars, Authors: K. Whaler and M. Purucker, Journal of Geophysical Research-Planets, 2006.
