GSH is a MATLAB package to do Global Spherical Harmonic Analyses (GSHA) and Synthesis (GSHS) for Crust1.0.

Global Spherical Harmonic package (MATLAB) that is able to analyse layered density structure of the Earth. It is also able to synthesise the resulting Stoke coefficients into potential fields, gravity fields, or gravity gradient fields at any height above the reference sphere. Some preliminary plotting of the fields has been made available.
