Global Trend in Land Water Storage
Terrestrial Water Storage Trend - LIS 10km Global DA
land NASA VEDA COG
In plain English
What it measures. Maps the long-term trend in total water stored on land, showing where regions are gaining or losing water over time.
How it's made. Calculated from NASA's Land Information System model output using a robust statistical trend method.
How & where you'd use it. Highlights regions drying out or wetting up, informing water-security and climate analysis.
