Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-7b4d3ba06c992ba2 descriptive
Jalisco's environment ministry runs a network of continuous air-quality stations across the Guadalajara metropolitan area and publishes an hourly index from it
Published field

What the mapping says

Caveat
The hourly publication frequency is stated by the ministry on its public air portal rather than on either page cited here.
