GRACE/GRACE-FO Level-4 Monthly Gravitational-Rotational-Deformation version 01 from NASA MEaSUREs HOMaGE

This data set contains global gridded, monthly solutions of the sea level equation (gravitational-rotational-deformational GRD components) using surface mass data from the GRACE and GRACE Follow-On (G/GFO) satellite missions, beginning in April 2002. The sea level components are provided for separate land domains to allow users the local contributions from various ice melt sources (e.g., Greenland, Antarctica, mountain glaciers), as well as non-glaciated land regions. The full record for each component is given in a separate netCDF file, and includes gridded data of radial deformation, geoid height and relative sea level, as well as timeseries of global mean barystatic sea level. The data are frequently updated as new monthly observations are acquired by the GFO mission.

These data are based on the gridded JPL CRI-filtered mascons (e.g., https://doi.org/10.5067/TEMSC-3JC634), and thus inherit all processing steps from those fields. For more information on GRD definitions and related terminology, please refer to Gregory et al., 2019 (https://doi.org/10.1007/s10712-019-09525-z).
