-----------------------------------------

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.

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 you can consult the 
GRACE/GRACE-FO Level-3 Data Product User Handbook. For the concepts and computations used to derive 
the quantities in the HOMAGE_GGFO_MSC_CRI_SALGRD_v01 data, please consult the following publications:
