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-364a7b01665eca6d quantitative

A peer-reviewed analysis of the network's first decade found only five stations held at least 50% valid PM10 data, with most gaps caused by equipment outages rather than unreliable readings

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: No support note recorded
Caveat: The network has since grown from 14 automatic stations to 20, an operator figure from 2026.

District publication of the declaring resolution. Earlier rounds (Resolución 0510 of 28 Mar 2019, Decreto Distrital 078 de 2020) added cargo-vehicle restrictions; those figures were only reachable via search snippets, so no tonnage or hours are asserted in the entry.

Carries the impact figure: 'For PM10, only five monitoring stations have at least 50% of valid data', and 'most of the data unavailability is due to equipment outages rather than unreliable measurements'. Also describes 14 automatic stations at the time, and criticises access as 'still focused on the needs of the data owner'. Dates network operation from 1998, against the operator's 1997.

Spatial-coverage counterweight: stations near the geographic centre share the most information with each other, while outskirts stations are singular — redundancy in the centre, thinner coverage at the edges.

Exposure counterweight: in-bus PM2.5 and black carbon inside TransMilenio far exceed ambient levels recorded by fixed stations, with a strong relationship between bus emission standard and in-vehicle concentration (Euro II/III roughly twice the stricter-standard buses).

Known limits of this passport

Publisher names and source languages have not yet been classified; domains are recorded without guessing.
Existing source notes are descriptive locators, not page- or paragraph-exact citations.
A missing archive, publication date or content hash is shown as null rather than inferred.
The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
