UK Environmental Intelligence Catalogue

The environmental catalogue builds a reusable, auditable inventory of UK environmental data sources. It supports SCC Air Quality and other investigations without treating inclusion in a directory as proof of data quality.

Catalogue architecture

Discover, record, validate.

The public GitHub repository documents Python tools, a versioned SQLite catalogue, deterministic source records, provenance hashes and resource-level validation.

It includes opt-in discovery of official CKAN and ArcGIS sources, metadata completeness checks and bounded reachability and licensing reviews. Candidate records are not automatically promoted to verified.

  • Environmental and air-quality source discovery.
  • Publisher metadata, licence, format, coverage and source lineage.
  • Append-only validation history and explicit candidate/degraded/retired states.

Related research

Linked to Air Quality, not the same thing.

SCC Air Quality is the topic-specific research and monitoring programme; the environmental catalogue is a broader reusable source-inventory and validation component.

Automated clustering or AI enrichment, where configured, remains advisory and cannot upgrade a source's evidence status without validation. The catalogue README explicitly declines comprehensive-coverage claims.

Evidence boundary

Current state and validation

Project identity and associated repositories were checked on 24 October 2026. A repository or document's existence does not establish that its public website, latest build, pipelines or scientific conclusions have been validated. Claims and illustrative material remain subject to project-specific review.
