Magnetic Analysis Code for Download

    MATLAB m-files are available for download from the WHOI anonymous ftp site shown below. These magnetic processing programs are ASCII scripts written for MATLAB version R11. The syn2d.m and inv2d.m scripts invoke the Parker (1973) and Parker and Huestis (1974) Fourier transform approach and are in part based on original Fortran77 code of Steve Miller and Prof. Ken Macdonald (UCSB). The syn3d.m and inv3d.m invoke the inversion for map data. Other specialty scripts such as direct inversion (Hussenoeder et al., 1996) and GMT grid i/o for matlab are available also. Please contact Maurice Tivey (mtivey at whoi dot edu) for more information.

    New updated Matlab mfiles are available on the ftp site below for calculating the newly released International Geomagnetic Reference Field (IGRF) for year 2020 back to 1900. The m-file magfd.m and associated binary *.mat IGRF coefficient files for each 5 year epoch from 1900 to 2020 are also available for download. If you have previously used this software make sure you download and update all files. See folder igrf on ftp site.

    Here is the link to the official IAGA V-MOD working group release of the 2020 coefficients, officially (and ambiguously) known as IGRF-13.
