Global Surface Water Runoff

Surface runoff - LIS 10km Global DA
land NASA VEDA COG
In plain English

What it measures. Maps surface runoff worldwide, the rain and snowmelt that flows over the ground rather than soaking in, 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. Supports flood forecasting and understanding how water moves across landscapes.
