Air quality today
The air quality in Cloquet, Minnesota is rated as Good today. The primary pollutant identified is PM2.5 (fine particles), based on a single valid measurement.
According to OpenAQ data, the measured concentration of PM2.5 is 2.5 µg/m³. 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 air‑quality feed for Cloquet draws on a single monitoring location, so the dataset contains just one row of observations. That lone station supplies data for two pollutants: ozone (O3) and fine particulate matter (PM2.5). The most recent ozone reading was recorded on 2025-11-04 at 19:00 UTC, while the latest PM2.5 measurement comes from 2026-02-10 at 23:00 UTC. Because only one of the two rows falls within the past week, the overall freshness score is modest; half of the data points are older than seven days, and there are no entries from today or the last three days.
Both pollutants show a single reported value rather than a range of measurements. Ozone is consistently logged at 0.036 ppm, with that figure representing the minimum, median, maximum, 10th percentile and 90th percentile for the dataset. Likewise, PM2.5 is recorded uniformly at 2.5 µg/m³ across all statistical descriptors. This lack of variation indicates that each pollutant has only one snapshot in time rather than a series of observations that would reveal fluctuations.
Because coverage rests on just one sensor, spatial representation across Cloquet is limited; conditions elsewhere in the city may differ from those captured at the Fond du Lac site. The dataset’s age distribution also points to gaps: one entry is recent (within seven days) and the other is classified as “old,” meaning it predates the last week. Consequently, while the available numbers give a clear picture of what was measured at that moment, they do not provide a continuous or city‑wide view of air quality trends.

Data notes
The data shown for Cloquet reflects a single valid measurement and is updated within 3 days, with the most recent reading recorded at 2026‑02‑10T23:00:00+00:00. This snapshot provides a brief view of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
