Overview
This documentation is intended to explain how to compute spherical harmonics from model outputs for comparing with or correcting time-variable gravity measurements from the GRACE/GRACE-FO missions. This software was developed with the goal of supporting science applications for time-variable gravity.
The model-harmonics projects consists of extension routines for the set of gravity-toolkit tools.
