Daily topsoil wetness across Europe (Copernicus)

hydrosphere ESA ESA Copernicus active COGNetCDF
In plain English

What it measures. Tells you how wet or dry the very top few centimetres of soil are, given as a percentage of how saturated the soil is.

How it's made. ESA Copernicus derives it from the C-band radar (C-SAR) on the Sentinel-1 satellites, providing daily 1-kilometre coverage of continental Europe.

How & where you'd use it. Valuable for farmers planning irrigation, for drought and wildfire risk warnings, and for flood forecasting.

Official description

Provides information on the relative water content of the top few centimeters soil, describing how wet or dry the soil is in its topmost layer, expressed in percent saturation. Daily observations are available for the continental Europe in the spatial resolution of 1 km and with the temporal extent from October 2014 to present.
