Air quality today

The air quality in Bastia, Corsica is currently classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 1.6 and a PM10 reference value of 3.1, based on ten valid observations collected through OpenAQ.

What the data includes

The Bastia air‑quality dataset contains measurements for six pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). The data come from 14 individual rows recorded at three monitoring sites across the city, so each pollutant is not necessarily represented at every location.

The most recent observations are fairly current for most gases: NO₂, PM₁₀, O₃ and PM₂.₅ were all last updated on 2026‑02‑10 at 15:00 UTC, while the NO reading dates back to 2024‑03‑11 at 08:00 UTC. SO₂ is the oldest entry, with its sole value from 2023‑08‑10 at 08:00 UTC. This mix of timestamps means that for some pollutants (especially NO and SO₂) the available figure may not reflect present‑day conditions, whereas the other four compounds provide a snapshot that is less than two days old.

Across the recent data the measured concentrations are low and show limited variability. NO ranges from 0.9 to 7.2 µg/m³ with a median of 1.6 µg/m³; NO₂ stays between 4.9 and 6.7 µg/m³, median 4.9 µg/m³; O₃ is tightly clustered around 81 µg/m³ (80.7–82.6 µg/m³) with a median of 81.65 µg/m³; PM₁₀ varies from 2.6 to 4.0 µg/m³, median 3.1 µg/m³; PM₂.₅ is almost constant at 1.5–1.6 µg/m³, median 1.55 µg/m³; and SO₂ has a single reported value of 1.6 µg/m³. The narrow inter‑percentile ranges (10th to 90th percentiles) indicate that, where recent data exist, concentrations are relatively stable across the sampled sites.

Because the dataset includes only three stations and some older entries, it does not capture fine‑scale spatial or temporal fluctuations throughout Bastia. Users should keep in mind that conditions can differ by neighbourhood and time of day, especially for pollutants with fewer or outdated measurements.

Data notes

The data shown for Bastia are based on ten valid measurements and have been refreshed within three days, with the most recent update recorded at 2026‑02‑10T15:00:00+00:00. This snapshot reflects conditions captured by the monitoring network at that time; however, air quality can differ across neighbourhoods and change throughout the day, so local values may vary from those presented here.
