Global Snowpack Water Content

Snow Water Equivalent - LIS 10km Global DA
cryosphere NASA VEDA COG
In plain English

What it measures. Maps snow water equivalent worldwide, the amount of water held in the snowpack if it all melted, 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 forecast spring meltwater, water supply, and snowmelt flooding.
