Level-2 GSM
Monthly spherical harmonic coefficients from GRACE/GRACE-FO processing centers.
Data
Data Products
Keep data products explicit, versioned, and auditable.
Gridded EWH
Equivalent water height anomaly grids produced from corrected coefficients.
Mascon references
Independent products for spatial pattern and basin-series comparison.
Auxiliary data
GIA, SLR replacement terms, basin masks, hydrology models, and altimetry references.
Every product should keep its source, version, baseline, spatial grid, units, and filter route explicit.
