Air quality today

The air quality in Brampton today falls within the “USG” category according to OpenAQ data. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 37.79 µg/m³ based on ten valid observations.

No other pollutants are reported for this assessment, and the data reflect the current conditions captured by the monitoring network. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Brampton air‑quality record draws on eleven data rows from a single monitoring station, covering eight measured variables – nitrogen monoxide (NO), nitrogen dioxide (NO2), total nitrogen oxides (NOX), ozone (O3), fine particulate matter (PM2.5), coarse particles (PM10), ultrafine particles (PM1) and relative humidity. Most of the observations are recent: the latest timestamps for NO, NO2, NOX, O3, PM1, PM2.5 and relative humidity were recorded on 2026‑02‑10 at 22:00 UTC, meaning they have been refreshed within the past three days. The only older entry is the PM10 reading, which dates back to 2025‑01‑13 at 23:00 UTC and is flagged as “old data”.

The dataset shows a modest spread for particulate matter. PM2.5 values range from 20.0 µg/m³ up to 37.8 µg/m³, with a median of about 28.9 µg/m³, while the 10th‑percentile sits near 21.8 µg/m³ and the 90th‑percentile close to 36.0 µg/m³, indicating most recent measurements cluster in the mid‑twenties to low thirties. PM1 is reported as a single constant value of 23.60833333333333 µg/m³, and PM10 appears only once at 9.032666643460592 µg/m³, limiting any assessment of its variability.

Gaseous pollutants are all recorded at the same fixed level across the recent sample: NO consistently reads 0.001 ppm, NO2 0.012 ppm, NOX 0.014 ppm and O3 0.037 ppm. Relative humidity is captured as a single measurement of 50.61433340708414 %, also from the most recent update. Because most variables have only one or very few data points, especially the older PM10 entry, the picture of Brampton’s air quality is necessarily limited in spatial and temporal detail; conditions can differ across neighbourhoods and over time beyond what these rows convey.
