Daily soil moisture at depth across Europe (Copernicus)

CLMS SWI Europe 1km daily V1
hydrosphere ESA ESA Copernicus COGNetCDF
In plain English

What it measures. Estimates how moist the soil is at several depths, not just the surface, giving a fuller picture of water in the ground.

How it's made. ESA Copernicus combines Sentinel-1 radar (C-SAR) with ASCAT data from the Metop satellites to map continental Europe daily at 1 kilometre, covering 2015 to 2025.

How & where you'd use it. Supports agriculture, drought monitoring, and flood prediction by showing where the ground is becoming saturated or parched.

Official description

Quantifies the moisture condition at various depths in the soil. Daily observations are available for continental Europe in the spatial resolution of 1 km and with the temporal extent from January 2015 to 2025.
