What's in it
- Data offered docs-verified
- soil water index (SWI) layers at T=2, 5, 10, 15, 20, 40, 60, 100 · surface state flag (nominal, frozen, thawing, frozen with snow, wet snow) · quality flags for each SWI layer
- Coverage docs-verified
- continental Europe (bbox approx. -11,35 to 50,72) · 2025-07-12 onwards
- Resolution docs-verified
- 1 km spatial; daily temporal
- Update frequency llm-inferred
- daily observations; offline product with P2D timeliness
- Formats docs-verified
- GeoTIFF (cloud-optimized COG) · ZIP (zipped product) · STAC JSON metadata
- Access docs-verified
- licence 'other' under the Copernicus Land Monitoring Service data policy; HTTPS and Product assets require OIDC auth, S3 assets use S3 storage credentials
Useful for
- Use cases llm-inferred
- Antecedent wetness screening for flood risk assessments and FRA runoff context · Daily soil moisture time series as input to infiltration or runoff model calibration for catchments in Europe · Frozen/thawing surface state flags to inform winter earthworks and ground-condition planning
- Audience llm-inferred
- flood consultants · hydrologists · drainage engineers · geotechnical engineers · environmental consultants · GIS analysts
Limitations
- Constraints docs-verified
- Values flagged by low quality flags are less reliable · Pixels masked for water surface, low sensitivity (S40) and extreme slope · Short record: time series starts 2025-07-12 · Licence is 'other' and must be checked against the Copernicus data policy · Access to some assets requires OIDC or S3 credentials
