Air quality today

Today's air quality in Chamni is classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 16.46 micrograms per cubic meter. This PM2.5 value of 16.46 µg/m³ aligns with the Moderate classification. No other pollutant recorded a concentration that would alter the overall category.

Data is shown via OpenAQ, which aggregates observations from participating monitoring stations. The dataset comprises five valid measurements, providing the basis for the current assessment. PM10 measurements were not reported for this location, so no reference value is available. The combination of the PM2.5 concentration and the limited measurement count results in the Moderate rating. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Chamni dataset contains six measured pollutants – PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003 – collected from two monitoring stations. In total there are twelve rows of observations; five of those rows have been updated within the past 30 days while the remaining seven are classified as “old”. The most recent timestamps for PM1, PM2.5, relative humidity, temperature and UM003 are all from 2026‑02‑03 09:00 UTC, whereas the latest PM10 reading dates back to 2025‑01‑13 23:00 UTC.

Across the recent data the observed ranges are fairly broad. PM1 values span from roughly 12 µg/m³ up to 51 µg/m³ with a median around 32 µg/m³. PM10, based on older records, varies between about 26 µg/m³ and 89 µg/m³, median 57 µg/m³. PM2.5 ranges from 16 µg/m³ to 86 µg/m³, median near 51 µg/m³. Relative humidity covers 37 % to 69 %, median 53 %, while temperature runs from 14 °C to 29 °C, median 21 °C. The UM003 particle concentration is recorded between 2 170 and 12 074 particles/cm³, with a median of roughly 7 100 particles/cm³.

Because the PM10 series is older than the other pollutants, the dataset provides a less current picture of coarse particulate matter for Chamni. The mix of recent and older rows means that conditions can differ noticeably across locations and times, and the limited number of stations (two) restricts spatial detail. Users should keep in mind that the available numbers represent snapshots rather than continuous monitoring, especially for PM10.

Data notes

The dataset for Chamni includes five valid measurements and is updated within 30 days, with the most recent reading recorded on 2026-02-03 at 09:00 UTC. These values reflect a snapshot of conditions at the time of collection. Air quality can vary by location and time within the city, so the figures may not represent current or site‑specific conditions elsewhere in Chamni.
