Official archive-first current layer · The page renders from Delhi Air Health's hourly CPCB-linked archive first, so a slow upstream API cannot hold the interface open. Source timestamp and monitor provenance stay attached to every value.

Why should I care about this number?
What today's reading can—and cannot—tell you.
Useful signal
What the nearby ambient air looks like now.
The PM2.5/PM10 snapshot is tied to the named physical monitor and its timestamp. It is useful as an area-level reference for the campus.
Scientific boundary
Not your personal dose. Not automatically an AQI.
Local traffic, buildings, indoor filtration and your own breathing pattern can change actual exposure. A current PM snapshot is not promoted into an official AQI without the required averaging context.
Understand the number
PM2.5 and AQI are not the same thing.
See why averaging time, pollutant sub-indices and app methodology matter.

Current-value note: Latest stored CPCB OGD snapshot from the hourly collector. Source-observation age is 24.5 h; archive-capture age is 23.8 h. This is not a live-to-the-second measurement.
Official CPCB AQI
Not auto-imported into Delhi Air Health yet.
CPCB publishes official city/station AQI through its AQI portal and Sameer. We have not found a stable, documented machine-readable official AQI endpoint in the public OGD resource, so the site will not scrape an undocumented app feed and label it authoritative.

Measurement source
Campus ≠ monitor.
This is an ambient reading at a nearby monitor, not a measurement on campus or of personal exposure. Hourly collection and source publication latency can make the stored current layer lag the upstream feed.
The station match may be valid, but the latest current snapshot is stale. It should not be used as a description of the air right now.

Why this monitor: Nearest verified Delhi monitor in Delhi Air Health's owned CPCB-linked station archive (3.4 km from the campus reference point). The page uses the latest stored source snapshot rather than waiting on a fresh upstream request.
⚠ This reading is stale and should not be treated as current.
Measurement geometry
3.4 km straight-line distance
Shared physical monitor
This exact monitor also represents 3 nearby campuses. Equal readings between them are expected and are not independent measurements.
Today in context
What changed over the last 24 hours?
The chart uses one time series for the same physical monitor: OpenAQ hourly history. Missing hours stay missing; Delhi Air Health does not interpolate invented particulate values across gaps.
Delhi Air Health archive
The archive is connected, but this monitor has not accumulated a stored observation yet.
OpenAQ remains the displayed hourly source until our own archive has equal or stronger chart coverage. We never splice the two series together.
Archive PM2.5 0/24
Archive PM10 0/24
Archived CPCB OGD avg_value snapshots are charted as reported snapshots; they are not assumed to be validated one-hour means.
Recent direction
Not enough recent history
Only described when recent chart coverage and change are large enough to support the label.
Compared with recent days
Not enough history for context
Needs at least 3 sufficiently complete OpenAQ hourly windows; archived CPCB snapshots are not used for this average.
PM2.5 history coverage
0/24 hours
A 24-hour particulate average is used only with at least 16 valid OpenAQ hourly values.
PM10 history coverage
0/24 hours
PM10 is shown independently; a missing series is not back-filled from PM2.5.
No usable recent history is available right now.
The current CPCB snapshot above remains valid independently. Delhi Air Health checked its own archive when configured and the matched OpenAQ fallback, but neither supplied a 24-hour window with enough particulate observations to show responsibly.

What are nearby campuses seeing?
These are current campus-linked references, not long-term rankings. Shared monitors are flagged so duplicated station data are not mistaken for independent evidence.
Medicine + public health
Understand what you are breathing.
The live number becomes more useful when you understand particle size, deposition and why exercise changes inhaled dose.
Particles
What PM2.5 actually does
Follow fine particles from inhalation toward the peripheral airways and alveolar region.

Exercise
Why harder breathing matters
Minute ventilation changes the amount of ambient air—and particles—you inhale per minute.

Protection
N95 vs surgical mask
Filtration is only part of the story; fit and face-seal leakage matter too.
