Air quality today
The air quality in Mieres today falls into the Good category. The primary pollutant measured is PM10, which represents coarser particulate matter in the atmosphere.
Four valid measurements were recorded, and the reference value for PM10 is 2.7 micrograms per cubic metre. These data are shown via 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 dataset for Mieres includes six measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10) and sulphur dioxide (SO₂). All values come from a single monitoring location, identified as Jardines de Juan XXIII, so the city’s air‑quality picture is based on one station that contributed six rows of data.
The timestamps show a mixed level of freshness. The most recent updates are from 2026‑02‑09 03:00 UTC for NO₂, O₃, PM10 and SO₂, indicating those four pollutants have been recorded within the last week. In contrast, CO data are dated 2017‑12‑20 01:00 UTC and NO data to 2024‑01‑31 00:00 UTC, meaning they have not been refreshed for several years. Because of this uneven recency, the current snapshot is more reliable for the latter four pollutants than for CO or NO.
Across the six rows, each pollutant shows a single recorded value, so there is no observed range or variability in the dataset itself. The median and extreme values are identical: CO 100.0 µg/m³, NO 1.0 µg/m³, NO₂ 4.0 µg/m³, O₃ 35.0 µg/m³, PM10 2.7 µg/m³ and SO₂ 1.0 µg/m³. This uniformity reflects the limited number of observations rather than stable atmospheric conditions. Consequently, while the data give a concrete point‑in‑time picture for most pollutants, they cannot capture how air quality may differ across other parts of Mieres or change throughout the day.
