Global Groundwater Storage

Groundwater Storage - LIS 10km Global DA
land NASA VEDA COG
In plain English

What it measures. Maps how much water is stored underground worldwide, in millimetres, on a 10-kilometre grid.

How it's made. Modelled by NASA's Land Information System, which folds satellite measurements into a global land-surface simulation.

How & where you'd use it. Helps track groundwater depletion, droughts, and long-term water supply.
