| summary | Gridded surface mass anomalies, derived from Spherical harmonic coefficients representing an estimate of Earth\'s mean gravity field during the specified timespan derived from GRACE mission measurements. These grids represent the full magnitude of land hydrology and land ice. Further, they contain atmospheric and oceanic processes not captured in the accompanying GAC product. |
