The air quality in Senneterre today is classified as Good. The primary pollutant measured is PM2.5 (fine particles). Two valid measurements were recorded, showing a PM2.5 concentration of 2.9 µg/m³.
Data are shown via OpenAQ and reflect the current monitoring results for this location. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Senneterre currently contains measurements from a single monitoring site that has contributed two separate data rows. Both ozone (O3) and fine particulate matter (PM2.5) are reported, giving a basic picture of the city’s air composition. The most recent observations were recorded on 2026-02-10 at 22:00 UTC for each pollutant, meaning the freshest values are just a few days old and fall within the “updated within 3 days” freshness category.
Ozone is reported in parts per million with a single value of 0.036 ppm; this figure is both the minimum, median and maximum across the available rows, indicating no observed variation in the limited sample. PM2.5 is measured in micrograms per cubic metre and shows a consistent reading of 2.9 µg/m³, again identical for the minimum, median and maximum values. Because each pollutant has only one recorded point, there is no spread or percentile range to describe – the data set essentially captures a snapshot rather than a distribution.
With just one station contributing two rows, coverage is narrow both geographically and temporally. The lack of older or unknown‑timestamp entries means that while the recent readings are current, they do not reflect possible fluctuations throughout the day or across different parts of Senneterre. Consequently, the available data give a very limited view of air quality conditions, and any interpretation should keep in mind that actual concentrations may vary outside the narrow window captured here.
