Air quality today
The air quality in Arrest today is classified as Good. The primary pollutant measured is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 5.2 µg/m³ and a PM10 level of 7.7 µg/m³, based on three valid observations recorded by OpenAQ. 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 Arrest air‑quality record draws from a single monitoring site, so the dataset contains three pollutant series – ozone (O3), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µg (PM2.5). All three measurements were last refreshed on 2026‑02‑10 at 15:00 UTC, meaning the most recent data are less than three days old and therefore fairly current for this location.
Across the three series the observed values are identical for their minimum, median and maximum, indicating that only one reading is available for each pollutant. Ozone registers a concentration of 78.7 µg/m³, PM10 shows 7.7 µg/m³ and PM2.5 records 5.2 µg/m³. Because there is no spread in the data (the 10th‑percentile and 90th‑percentile match the single value), statistical descriptors such as range or variability cannot be derived beyond noting that each pollutant currently has a single reported figure.
The dataset’s breadth is limited to this one station, so spatial coverage within Arrest is minimal; conditions elsewhere in the city may differ from what these point measurements capture. Nonetheless, the freshness of the timestamps – all updated within the last three days – ensures that the snapshot reflects recent atmospheric conditions rather than historic or stale information.

Data notes
The current dataset for Arrest includes three valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 15:00 UTC, meaning it is updated within three days. This snapshot reflects conditions captured at that time; however, air quality can vary across different neighborhoods and change throughout the day, so values may differ from what you experience locally.
