In plain English
What it measures. Shows the moisture condition of soil at various depths beneath the surface across continental Europe.
How it's made. ESA Copernicus derives it daily at 1-kilometre resolution by merging Sentinel-1 radar with Metop ASCAT data, covering 2025 onward.
How & where you'd use it. Helps farmers, water planners, and emergency services judge soil wetness for irrigation, drought response, and flood risk.
