CLMS Surface Soil Moisture (SSM) Europe 1km daily v1 (COG)
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.

What's in it
- Data offered docs-verified
- surface soil moisture (ssm band; relative water content of top few cm, % saturation) · noise on surface soil moisture (noise band) · quality and mask flags (exceeding_min, exceeding_max, water_mask, sensitivity_mask, slope_mask, nodata)
- Coverage docs-verified
- Continental Europe (bbox -11.0, 35.0, 50.0, 72.0) · October 2014 to present (interval starts 2014-10-04, open-ended)
- Resolution docs-verified
- 1 km spatial (gsd 1000 m); daily temporal
- Update frequency docs-verified
- Daily (product timeliness P1D, offline category)
- Formats docs-verified
- GeoTIFF (cloud-optimized COG) · ZIP (zipped product archive)
- Access docs-verified
- Licence 'other' under the Copernicus Land Monitoring Service data policy. Assets are served via the Copernicus Data Space STAC catalogue; HTTPS and zipped Product assets use OpenID Connect auth, and S3 assets use S3 credentials. CREODIAS S3 is requester-pays.
Useful for
- Use cases llm-inferred
- Antecedent soil moisture context for FRA and runoff assessments across Europe, including the UK · Drought and dry-spell screening for water resource and abstraction assessments · Ground wetness and saturation context for earthworks and geotechnical planning (regional, not site-scale)
- Audience llm-inferred
- flood consultants · hydrologists · geotechnical engineers · GIS analysts · water resources consultants
Limitations
- Constraints llm-inferred
- Measures only the top few centimetres of soil, not root zone or groundwater · Coverage is continental Europe only; bbox extends to 35-72 N and -11 to 50 E · 1 km grid is regional, not suitable for site-scale analysis · Pixels flagged exceeding_min, exceeding_max, water, low-sensitivity, slope or nodata (255) must be masked before use · Offline product from Sentinel-1 C-SAR with roughly one-day timeliness · Authentication required for HTTPS and Product assets; CREODIAS S3 egress is requester-pays · Licence 'other' means redistribution terms should be checked against the data policy
