World Air Quality Index project
5 atlas entries in 5 cities cite this publisher, through 5 different documents.
What this page is. A non-governmental organisation. Membership is computed: every published entry citing a URL the registry attributes to World Air Quality Index project appears below. The classification says who publishes — never how strong the evidence is. That judgement stays on each entry, in the grade beside it.
✔ Every published entry is checked against the public sources it cites before publication.
