Planetary magnetic and gravity fields: Regional inversion using Slepian functions

Installation instructions: https://github.com/Slepian/Slepian/wiki.

DOI

These are the programs that I developed and used for my articles Internal and external potential-field estimation from regional vector data at varying satellite altitude and High-resolution local magnetic field models for the Martian South Pole from Mars Global Surveyor data.

The installation scripts automatically download all the SLEPIAN_Alpha, etc repositories, set up the folder structure, etc. The repository also contains demo functions for inversions and function constructions.

Near-surface geophysics software

You can download my near-surface Matlab-/Octave scripts, that I have been using for teaching and student research from NSGeophysics.

GPR-O Contains functions for ground penetrating radar data processing and plotting in 2D and 3D. The repository also contains an introductory text on how to use the software. Installation instructions are available on https://github.com/NSGeophysics/GPR-O/wiki

Seism-O Is a software package to simulate various near-surface seismic refraction/reflection data set for simple settings. The Matlab/Octave scripts are available on https://github.com/NSGeophysics/Seism-O. Check out the wiki page for simple download instructions.

Altitude-cognizant gradient vector Slepian functions

This is the repository SLEPIAN_Hotel that contains the programs to construct and use the altitude-cognizant gradient-vector Slepian functions presented in our research article Internal and external potential-field estimation from regional vector data at varying satellite altitude. This suite of programs requires other programs from SLEPIAN_Alpha, etc and the correct folder structure which can be set up easiest using these installation scripts and instructions.

General spherical vector Slepian functions

These are the spherical vector Slepian function software that I developed in collaboration with Frederik Simons, stored and maintained in the repository SLEPIAN_Golf. This suite of programs requires other programs from SLEPIAN_Alpha, etc and the correct folder structure which can be set up easiest using these installation scripts and instructions.

Background figure

The figure in the background shows the best-suited altitude-cognizant gradient vector Slepian function for external magnetic field constructed for spherical-harmonic degree 10, concentrated over North America and optimized for average satellite altitude 300 km and external field radius 400 km.
