Scientific evidence
Measurements, station and regional coverage, descriptive calculations, source records and stated limitations are the evidence available for review.
Access SCC Air Quality evidence in a form you can use
SCC Air Quality aims to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA. This is an improvement target, not a claim of independently verified full conformance.
Statement reviewed: 2026-09-17.
What we provide
- Keyboard-operable navigation and visible focus states.
- Responsive pages, headings, landmarks and descriptive links.
- HTML explanations and data tables alongside scientific visual material.
- CSV, JSON and GeoJSON evidence downloads where available.
- Plain-language explanations that retain every material limitation.
Known limitations
- Some interactive maps and dense tables may need additional screen-reader explanation.
- Browser-generated PDFs may not contain complete tagged-PDF semantics; use the canonical HTML page or request an alternative.
- Third-party documents and websites are outside SCC Air Quality's direct accessibility control.
Testing and contact
Each release should be checked for keyboard access, focus, headings, labels, contrast, zoom, mobile reflow, reduced motion, image alternatives and data-table structure. Independent WCAG review remains required.

Scientific evidence and software assurance are different
Engineering assurance
Automated checks confirm that the pipeline followed its declared rules. They do not constitute peer review, accreditation, regulatory approval or institutional endorsement.
