AGU Fall Meeting 2011 Abstract
Magnetic fields within the solar system provide a strong organizing
force for processes active both within a planet or moon, and outside of
it.
In the interest of stimulating research and education in the field of
comparative planetology, we present documented Fortran and MATLAB
source codes and benchmarks to the latest models for planets and
satellites that host internal magnetic fields.
This presentation is made in the context of an interactive website:
http://planetary-mag.net.
Models are included for Earth (Comprehensive model CM4 of
Sabaka et al., 2004, Geophysics J. Int.),
Mercury
(
Anderson et al., 2011, Science),
the Moon
(
Purucker and Nicholas, 2010, JGR),
Mars
(
Langlais et al., 2004, JGR;
Lillis et al., 2010, JGR),
and the outer planets Jupiter, Saturn, Uranus, and Neptune
(
Russell and Dougherty, 2010, Space Science Reviews;
Holme and Bloxham, 1996, JGR).
All models include magnetic fields of internal origin, and
fields of external origin are included in the models for Mercury, the
Earth, and the Moon.
As models evolve, we intend to include magnetic fields of external
origin for the other planets and moons.
This website allows the user to select a coordinate system, such as
planet-centered, heliocentric, or boundary normal, and the location
within that coordinate system, and the vector magnetic field due to
each of the component source fields at that location is then calculated
and presented.
Alternatively, the user can input a range as well as a grid spacing,
and the vector magnetic field will be calculated for all points on that
grid and be made available as a file for downloading.
