What This Air Quality Project is ready for

This Air Quality Project is ready for external methodology, provenance, data-gap and challenge interrogation. It is not yet a public claims engine for causation, breach, compliance or health effects.

Project evolution and external challenge

From a facility-context prototype to an England-wide, data-led observatory

The project began with a narrower facility-context purpose. The present pipeline discovers and evaluates official monitoring evidence first. Supplementary locations do not seed the monitoring screen, and unvalidated inherited material has no scientific influence.

This is an independent open-source project, not an official, accredited or peer-reviewed authority. Reviewers are invited to challenge the sources, station selection, units, timestamps, missing-data treatment, calculations, coverage rules and public interpretation.

External interrogation lenses

IAQM / AQEG / atmospheric-science review

  • Are target-matching and monitor-selection rules sufficiently conservative?
  • Are receptor, background and comparator monitors separated correctly?
  • Are meteorology and time-alignment gates explicit before interpretation?

Public-health and reference-value review

  • Does the public output avoid unsupported health-causation claims?
  • Are pollutant benchmarks separated from source attribution?
  • Are vulnerability/receptor flags presented as context, not diagnosis?

Clean Air Programme / Clean Air Fund / EEA

  • Is the data provenance clear enough for reuse and challenge?
  • Are data gaps visible and actionable?
  • Are official networks and open-data feeds preserved with source URLs and access dates?

UKWIN / ToxicoWatch / GAIA / Zero Waste reviewers

  • Are permitting, compliance, emissions and waste-policy questions kept traceable?
  • Are campaign-source materials separated from official records and peer-reviewed studies?
  • Are alternative explanations and contrary evidence recorded before public claims?

Named scientific reviewers and independent experts

  • Which source record supports each statement?
  • What uncertainty remains before a stronger claim could be made?
  • What additional monitoring, modelling or records would materially improve confidence?

Manual review required

Benchmark cards are public-health context only. They are not source-attribution findings.

Claim boundary

No causal, legal, medical, regulatory, laboratory, comparative-risk or source-attribution determination is made by the automated output.

How to read this page

Scientific evidence and software assurance are different

Scientific evidence

Measurements, station and regional coverage, descriptive calculations, source records and stated limitations are the evidence available for review.

Engineering assurance

Automated checks confirm that the pipeline followed its declared rules. They do not constitute peer review, accreditation, regulatory approval or institutional endorsement.
