CLMS Water Level (WL) Rivers Global vector daily V2 (GeoJSON)

Defined as the height, in meters above the geoid, of the reflecting surface of continental water bodies. It is observed by space radar altimeters and data are available at global scale in near real time in vector format with the temporal extent from 2002 to present.

What's in it

Data offered docs-verified: river water level: height above geoid (m) of continental water bodies
Coverage docs-verified: Global · 2002 to present (per description; STAC temporal extent starts 2008-07-12)
Resolution docs-verified: Daily (temporal); spatial resolution not stated
Update frequency docs-verified: Near real time (product timeliness tag P3D)
Formats docs-verified: GeoJSON
Access docs-verified: Credentials indicated by docs: OIDC (CDSE identity) for HTTPS and S3 credentials for storage; licence 'other' (CLMS data policy)

Useful for

Use cases llm-inferred: Supplementary river stage time series for FRA baseline checks where gauges are sparse · Regional river level trend review for flood risk assessments · Desk-based screening of water level change ahead of site surveys
Audience llm-inferred: flood consultants · hydrologists · GIS analysts

Limitations

Constraints llm-inferred: Entry auth is null, but docs list OIDC and S3 auth schemes · Time span conflict: description says from 2002, STAC extent starts 2008-07-12 · Licence is 'other'; check the CLMS data policy before reuse in client deliverables · No spatial resolution or gauge-level detail stated in docs · Sentinel-3 altimeter platforms (per docs summaries) suggest track-based sampling rather than continuous coverage · CREODIAS S3 storage is requester-pays · Docs bbox spans latitude -53.93 to 74.05, so polar regions fall outside coverage
