CLMS Water Level (WL) Lakes 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 1992 to present.

What's in it

Data offered docs-verified: lake and reservoir water level (height above geoid, m) · continental water body surface height from space radar altimeters
Coverage docs-verified: Global scale; STAC bbox [-154.9, -50.33, 170.17, 71.48] · 1992-09-26 to present (open-ended)
Resolution docs-verified: Daily (temporal); spatial resolution not stated
Update frequency docs-verified: Near real time; exact update cadence not stated
Formats docs-verified: GeoJSON
Access docs-verified: Licence 'other' under the Copernicus Land Monitoring Service data policy. HTTPS assets use CDSE OpenID Connect auth; S3 storage is available (CDSE S3 not requester-pays, CREODIAS S3 requester-pays). Free or paid status not stated.

Useful for

Use cases llm-inferred: Lake and reservoir level trend analysis for water-resource desk studies outside gauged areas · Remote water level context for flood risk or drought assessments on large lakes · Time-series screening of water body levels in GIS for environmental baseline reporting
Audience llm-inferred: hydrologists · water resources engineers · GIS analysts · environmental consultants

Limitations

Constraints llm-inferred: Spatial extent is a bounding box (lat -50.33 to 71.48), not all land areas · No spatial resolution stated in docs · HTTPS access requires CDSE OpenID Connect authentication, although catalogue auth is listed as null · CREODIAS S3 storage is requester-pays · Licence is 'other', so reuse terms need checking against the Copernicus data policy
