Synthetic gravity disturbances from CRUST1.0 and their Monte Carlo dispersion

Synthetic gravity disturbances forward-modelled from the CRUST1.0 crustal model, evaluated at 255 km altitude on a 1-degree global grid, together with six Monte Carlo ensembles of 200 realizations each in which Moho depth and Moho density contrast are perturbed by spatially correlated random fields of increasing maximum spherical-harmonic degree. The deposit includes the unperturbed field, its low-pass filtered counterpart, the corresponding degree power spectra, and the ensemble mean and dispersion maps before and after filtering. No observed gravity data are used. See README.md for grid geometry, units and file descriptions.
