Air quality today
The air quality in Dearborn, Michigan is currently rated as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 25.0 and a PM10 reference value of 48.0, based on seven valid observations.
These figures are presented through OpenAQ data. 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 Dearborn air‑quality dataset currently contains measurements from a single monitoring station, giving one row of data for each pollutant tracked. The available parameters are fine particulate matter (PM2.5), coarse particulate matter (PM10), ultrafine particles (PM1), relative humidity, temperature and particle count (UM003). For PM2.5 the most recent value is 25.0 µg/m³ recorded on 2026‑02‑10 23:00 UTC; PM10 shows a single reading of 48.0 µg/m³ from the same timestamp. The ultrafine particle metric (PM1) and the ancillary variables were last updated earlier, on 2026‑02‑07 16:00 UTC, with values of 0.0 µg/m³ for PM1, 25.33 % for relative humidity, 7.13 °C for temperature and 30.48 particles/cm³ for UM003.
Because there is only one station contributing data, the coverage across pollutants is uneven: PM2.5 and PM10 have fresh updates within the past week, while the other four measurements are older by three days but still fall inside a 30‑day freshness window. The recorded range for PM2.5 spans from a minimum of 0.0 µg/m³ to a maximum of 25.0 µg/m³, with a median of 12.5 µg/m³, indicating that the single recent reading sits at the upper end of its observed distribution. In contrast, PM10 shows no variation at all – the minimum, median and maximum are all 48.0 µg/m³, reflecting a lack of multiple observations to capture any spread.
Overall, the dataset provides a snapshot rather than a continuous picture of air quality in Dearborn. With only one reporting location and limited recent timestamps for half of the parameters, conditions can differ across neighborhoods and times of day that are not captured here. Users should keep in mind that these figures represent the most current available data but do not convey the full temporal or spatial variability within the city.

Data notes
The data shown reflects seven valid measurements and is updated within 3 days, with the most recent reading recorded at 2026‑02‑10T23:00:00+00:00. These values provide a current snapshot of air quality in Dearborn, Michigan, but conditions can differ across neighborhoods and change throughout the day, so this information represents only a brief moment in time.
