Air quality today

The air quality in Tomé today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements from three monitoring stations show a PM2.5 reference value of 14.0 µg/m³ and a PM10 reference value of 27.0 µg/m³.

Data are shown via OpenAQ, reflecting the latest available readings for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Tomé includes five recorded rows covering a single monitoring site, Liceo Polivalente. All five key pollutants measured by OpenAQ are present: nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm and smaller (PM10), fine particulate matter 2.5 µm and smaller (PM2.5), and sulfur dioxide (SO2). The two older measurements, NO2 at 2.03 µg/m³ and O3 at 48.11 µg/m³, were last updated on 2021‑08‑20 20:00 UTC, while the three newer readings—PM10 at 27.0 µg/m³, PM2.5 at 14.0 µg/m³ and SO2 at 10.96 µg/m³—were refreshed on 2026‑02‑10 13:00 UTC, falling within the “updated within three days” freshness category.

Across the five rows the values are uniform: each pollutant shows a single recorded figure that is simultaneously its minimum, median and maximum, with the 10th and 90th percentiles matching that same number. This indicates no observed variability in the data for the periods captured. The older NO2 and O3 entries suggest that recent information on these gases is lacking, whereas the particulate matter and sulfur dioxide readings are current.

Overall, the coverage is limited to one location, so city‑wide conditions may differ elsewhere or at other times. The dataset provides a snapshot of each pollutant’s concentration at Liceo Polivalente, but the absence of recent NO2 and O3 data means those aspects of air quality cannot be assessed with up‑to‑date information.
