Surface Soil Moisture 2014-present (raster 1 km), Europe, daily - version 1
Surface Soil Moisture (SSM) is the relative water content of the top few centimetres soil, describing how wet or dry the soil is in its topmost layer, expressed in percent saturation. It is measured by satellite radar sensors and allows insights in local precipitation impacts and soil conditions.
SSM is a key driver of water and heat fluxes between the ground and the atmosphere, regulating air temperature and humidity. Moreover, in its role as water supply, it is vital to vegetation health. Vice versa, SSM is very sensitive to external forcing in the form of precipitation, temperature, solar irradiation, humidity, and wind. SSM is thus both an integrator of climatic conditions and a driver of local weather and climate, and plays a major role in global water-, energy- and carbon- cycles.
Knowledge on the dynamics of soil moisture is important in the understanding of processes in many environmental and socio-economic fields, e.g., its impact on vegetation vitality, crop yield, droughts or exposure to flood threats.
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.

- Purpose
-
This product is first designed to fit the requirements of the Global component of the Copernicus Land service. It can be also useful for all applications related to environment monitoring.
- Credit
-
SSM1km products were generated by the Global Land Service of Copernicus, the Earth Observation programme of the European Commission. The research leading to the current version of the product has received funding from various European Commission Research and Technical Development programs. This product has been generated from Sentinel-1 C-band SAR observations distributed by ESA.

The Copernicus component is governed by Regulation (EU) No 2021/696 of the European Parliament and of the Council of 28 April 2021 establishing the Union Space Programme and the European Union Agency for the Space Programme and repealing Regulations (EU) No 912/2010, (EU) No 1285/2013 and (EU) No 377/2014 and Decision No 541/2014/EU. Within the Copernicus component, a portfolio of land monitoring activities has been delegated by the European Union to the European Environment Agency (EEA) and the DG Joint Research Centre of the European Commission.
The Copernicus land monitoring products and services are made available on a principle of full, open and free access, as established by the Commission Delegated Regulation (EU) No 1159/2013 of 12 July 2013.
Free, full and open access to the products and services of the Copernicus Land Monitoring Service is made on the conditions that:
1. When distributing or communicating Copernicus Land Monitoring Service products and services (data, software scripts, web services, user and methodological documentation and similar) to the public, users shall inform the public of the source of these products and services.
2. Where the Copernicus Land Monitoring Service products and services have been adapted or modified by the user, the user shall clearly state this.
3. Users shall make sure not to convey the impression to the public that the user's activities are officially endorsed by the European Union.

Resource lineage
- Statement
-
The SSM algorithm is originally developed at Vienna University of Technology (TU Wien) and first terrain geo-corrects and radiometrically calibrates the Level-1 Sentinel-1 C-band SAR backscatter values. Then, in the TUWien-Change-Detection model, dry and wet soil conditions are modelled from long term backscatter measurements and the backscatter is normalized to the common reference angle of 40 degrees. The relative surface soil moisture estimates range between 0 and 100 percent and are derived by linearly scaling the angle-normalized backscatter between the lowest/highest backscatter values at each individual location. The relative SSM is provided as percent saturation and can be further translated to absolute volumetric soil moisture by using porosity information.
