GRACE gravity field inversion package
GRACE_Tiles is a library of routines that can be used to create regularized, gridded, global fields of surface mass variability from unconstrained GRACE spherical harmonic coefficients. These scripts will take GRACE Stokes coefficients and process them in a manner similar to 'mascon' approaches, allowing a user to regularize the gravity field solutions using constraints that are defined in the spatial domain (as opposed to in the spectral domain). Users can easily change the regularization parameters and tile shapes.
