Air quality today
The air quality in Auclair today is classified as Good. The primary pollutant measured is PM2.5 (fine particles). According to the latest data, the PM2.5 concentration is 2.8 µg/m³, based on two valid measurements recorded by OpenAQ.
Overall conditions are favorable for outdoor activities, and no additional pollutants reached reporting thresholds. 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 Auclair air‑quality record includes data from two monitoring entries, one for ozone (O₃) and one for fine particulate matter (PM₂.5). Both observations were recorded at the same station in Auclair and are recent: the latest update for each pollutant was on 2026-02-10 22:00 UTC, which falls within the past three days. No older or unknown‑date entries are present in the dataset.
For ozone, the single reading shows a concentration of 0.042 ppm. Because there is only one value, the minimum, median, maximum and the 10th and 90th percentiles are all identical at 0.042 ppm, indicating no observed variation within this limited sample. The same pattern holds for PM₂.5, where the measured level is 2.8 µg/m³ across the board, again with no spread in the statistics.
These figures illustrate that the current data set provides a very narrow snapshot of air quality in Auclair—just one recent measurement per pollutant and no historical depth. While the timestamps are fresh, the lack of multiple rows means there is no information on how concentrations might change over time or differ across locations within the city. Consequently, any description of local conditions should acknowledge that the available data represent a single point in time rather than a comprehensive view of air quality trends or spatial variability.

Data notes
The data shown for Auclair reflects two valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC, meaning it is updated within three days. These values provide a snapshot of current conditions, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this brief overview.
