Data operations

Can we trust what the site is showing?

Current readings, station geography and historical coverage are audited separately. That matters because a source can have excellent station metadata but still lag as a real-time feed.

CPCB current snapshots + owned history archive

Current particulate snapshots come from CPCB's official Open Government Data feed on data.gov.in. When configured, Delhi Air Health stores those monitor snapshots itself every hour; OpenAQ remains a secondary history and station-geography source.

Campuses

Entries currently in the Delhi campus registry.

Current snapshots

34/34

Campuses with a current PM2.5 or PM10 value from the active provider.

Current gaps

Campuses without a safely matched current CPCB PM2.5/PM10 snapshot.

24h chart coverage

33/34

Campuses with at least 16 PM2.5 points from the stronger available history source. Archived CPCB snapshots remain descriptive and are not automatically treated as validated hourly AQI input.

1 matched current snapshot is older than 6 hours.

Delhi monitor network + nearby NCR ring

The archive follows the monitoring network, not just the campuses

This map is rendered from Delhi Air Health's own latest archived CPCB-linked station rows, so it does not disappear when a secondary geography provider is unavailable. Delhi feeds are kept separate from nearby NCR feeds.

Collector healthy

Our CPCB snapshot archive is accumulating automatically

The cloud collector stores one row per physical monitor and CPCB source timestamp. Repeated runs at the same source timestamp are merged instead of being mistaken for new hourly observations.

CPCB OGD supplies current station snapshots. OpenAQ supplies station geography in bulk without requesting sensor histories, which keeps normal page loads well below its free rate limit. A single campus detail page may request matched 24-hour history on demand. If either layer is missing, the interface says so.
