Air quality today
The air quality in El Maíllo is classified as Good today. The primary pollutant measured is PM10, and the reference value for this particle size is 1.0. Four valid measurements were recorded to determine the current assessment.
Data are shown via OpenAQ and reflect the latest available readings for the city. 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 dataset for El Maíllo contains measurements from five monitoring rows, each reporting a single pollutant: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀) and sulphur dioxide (SO₂). All values are expressed in micrograms per cubic metre. The most recent data points were recorded on 2026‑02‑09, with the exception of NO, whose latest entry dates back to 2024‑01‑29, indicating that four of the five pollutants have been updated within the last seven days while one remains older.
Each pollutant shows a single reported figure, meaning there is no observed spread in the data. For NO the value is consistently 3.0 µg/m³; for NO₂, PM₁₀ and SO₂ the constant reading is 1.0 µg/m³; and O₃ registers a steady 81.0 µg/m³. Because the minimum, median and maximum are identical for every pollutant, the dataset does not reveal any variability across time or location within the city.
Overall, the coverage is limited to one station per pollutant, so spatial representation is narrow and temporal depth is shallow. While most measurements are fresh, the older NO reading highlights that some parameters may lag behind current conditions. Consequently, the snapshot provides a basic overview of current concentrations but cannot capture fluctuations that might occur at different sites or times in El Maíllo.

Data notes
The data shown for El Maíllo are based on four valid measurements and were updated within three days, with the latest reading recorded at 2026‑02‑09T15:00:00+00:00. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and throughout the day, so values may not represent the entire city’s current environment.
