This dataset provides a Level-3 (gridded on 0.5 deg x 0.5 deg) GRACE product representing Equivalent Water Height (EWH, units: cm) at a 5-day to sub-weekly temporal resolution. It is derived exclusively from GRACE residual Level-1B data*(**), without the use of external geophysical or hydrological models and does not involve inversion.

The dataset covers the period from April 2002 to August 2016.

To support usage and interpretation, the repository includes:

• Python plotting utilities (/plotting_tools) for visualizing the results
• Validation resources (/quality_checks) summarizing multiple quality control checks applied to the data
• A complementary monthly file (bin_count.nc) containing monthly LGD observation bin counts for each spatial grid cell (2 deg x 2 deg).

This dataset is intended for users seeking higher-frequency gravity field variations based solely on GRACE residuals, and may be particularly valuable for hydrological and geophysical analyses.
