Sentinel-1 Level-1C Ground Range Detected (GRD)
Sentinel-1 is a pair of Synthetic Aperture Radar (SAR) imaging satellites launched in 2014 and 2016 by the European Space Agency (ESA). Their 6 day revisit cycle and ability to observe through clouds makes this dataset perfect for sea and land monitoring, emergency response due to environmental disasters, and economic applications. This dataset represents the global Sentinel-1 GRD archive, from beginning to the present, converted to cloud-optimized GeoTIFF format.

- Resolution docs-verified
- Pixel spacing values listed as 3.5, 10, 25 and 40 m; the STAC summaries do not state which value applies to which product mode
- Update frequency docs-verified
- Satellite revisit cycle of about 6 days (acquisition frequency). Catalogue refresh cadence is not stated.
- Formats docs-verified
- Cloud-optimized GeoTIFF · XML (SAFE manifest, noise, calibration and product schemas) · PNG thumbnail · STAC JSON / GeoJSON (catalogue)
- Access docs-verified
- Licence: proprietary, under Copernicus Sentinel data terms. Data is hosted on AWS S3 (eu-central-1) and is requester-pays. Free access and the absence of authentication are not stated in DOCS.
Useful for
- Use cases llm-inferred
- Flood extent mapping from SAR for FRA baseline and post-event review, independent of cloud cover · Multi-temporal backscatter change detection for construction-site or wetland monitoring · Water body and saturated-area mapping to inform drainage strategy or BNG habitat baselines
- Audience llm-inferred
- flood consultants · hydrologists · GIS analysts · ecologists · geotechnical engineers
Limitations
- Constraints llm-inferred
- Requester-pays S3 access may incur download costs · Proprietary Copernicus Sentinel data terms apply · Revisit is about 6 days, so it is not a daily monitoring source · GRD is a ground-range amplitude product rather than SLC, so it is unsuitable for InSAR (llm-inferred) · UK-specific coverage and catalogue update cadence are not stated in DOCS
