Global Total Water Stored on Land
Terrestrial Water Storage - LIS 10km Global DA
land NASA VEDA COG
In plain English
What it measures. Maps terrestrial water storage worldwide, all the water held in soil, groundwater, snow, and surface water combined, in millimetres.
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 droughts, floods, and long-term changes in regional water resources.
