Air quality today

The air quality in Algete today is classified as Good. The primary pollutant identified is PM2.5, fine particulate matter measured by the monitoring network.

Six valid measurements were recorded, with a reported PM2.5 concentration of 7.0 µg/m³. No reference value is provided for PM10 at this time. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Algete pulls information from a total of thirteen measurement rows, two of which are classified as older entries while the remaining eleven are recent observations. Four pollutants are represented: nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3) and fine particulate matter (PM2.5). For NO2, O3 and PM2.5 the most recent reading was recorded on 2026‑02‑09 at 15:00 UTC, which falls within the “updated within seven days” category; the NO sensor last reported a value on 2024‑02‑29 at 00:00 UTC and is therefore considered old data.

Across the recent rows, NO2 values range from a low of 22.0 µg/m³ to a high of 33.0 µg/m³, with a median of 27.0 µg/m³ and the central 80 % of observations falling between 23.0 and 31.8 µg/m³. Ozone shows a broader spread, moving from 34.0 up to 53.0 µg/m³; the median sits at 50.0 µg/m³ and the 10th‑90th percentile band runs from 37.2 to 52.4 µg/m³. PM2.5 concentrations are comparatively low, varying between 6.0 and 11.0 µg/m³, a median of 7.0 µg/m³ and an inter‑percentile range of 6.2 to 10.2 µg/m³. The older NO data is limited to a single recent value of 1.0 µg/m³, with historical readings spanning from 1.0 to 4.0 µg/m³ and a median of 2.5 µg/m³.

These figures illustrate that the most current information is available for three of the four pollutants, while NO coverage relies on older measurements. The recent data set captures modest variability in each pollutant’s concentration, but because the station count is limited and one sensor reports only outdated values, the picture of air quality in Algete may not reflect short‑term fluctuations across all neighborhoods.

Data notes

The dataset for Algete includes six valid measurements and is updated within three days, with the most recent data recorded on 2026‑02‑09 at 15:00 UTC. This snapshot reflects conditions at that specific time; air quality can vary across different neighborhoods and moments throughout the day, so values may not represent current or location‑specific conditions elsewhere in the city.
