Research

Two models are currently being used in our research:

1. an n = 70 spherical harmonic coefficient set derived using Mars Global Surveyor AB(binned averages), SPO, and MPO data: Display / Download Zipped
2. an n = 90 spherical harmonic coefficient set derived using Mars Global Surveyor AB(raw data), SPO, and MPO data: Display / Download Zipped
3. data set used to calculate n=90 model in paper. (see electronic supplement in paper for format).
   
4. Click here to download a set of subroutines to calculate the field from the above coefficients.

Magnetic Field Maps \w Topography

These pages contain for each region a topographic map, as well as maps of the magnetic components: X(North), Y(East), Z(Vertical Downward) calculated at 200 km above the spheroid using FSU_mars90. Values of field are in nanoTesla, latitudes are in geodetic coordinates.
