Air quality today

The air quality in Ghent today is classified as Good. The primary pollutant identified for the current assessment is PM2.5 (fine particles).

Measurements from OpenAQ indicate a PM2.5 reference value of 4.74925 and a PM10 reference value of 11.3, based on 13 valid observations collected across the city. These figures reflect the concentrations used to determine the Good category for today’s air quality. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Ghent’s air‑quality feed contains six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10), fine particulate matter 2.5 µm or less (PM2.5) and sulphur dioxide (SO₂). The dataset comprises 22 rows of observations drawn from six monitoring stations across the city, giving a modest spatial coverage that captures conditions at several key locations but does not represent every neighbourhood.

The most recent data for four pollutants (NO₂, PM10, PM2.5 and O₃) were recorded on 2026‑02‑10 18:00 UTC, meaning they are refreshed within the last three days. In contrast, CO and SO₂ rely on a single older record from 2023‑01‑09 05:00 UTC, so information for these gases is considerably less current. Across all pollutants the median values cluster in the low double digits: NO₂ averages 15.5 µg/m³ (range 7.5–24.0), PM10 sits at 8.3 µg/m³ (6.8–28.4) and PM2.5 at 4.74925 µg/m³ (3.454–18.8). Ozone shows a broader spread, with a median of 38.5 µg/m³ and extremes from 18.5 up to 58.5 µg/m³. The particulate data are fairly tight around their medians – the 10th‑percentile for PM10 is 7.4 µg/m³ and the 90th‑percentile 21.56 µg/m³, while PM2.5 ranges from 3.80 to 13.35 µg/m³ between those percentiles.

Because CO and SO₂ are based on a single old measurement (both reported as 135.0 µg/m³ for CO and 0.0 µg/m³ for SO₂), their values cannot reflect recent changes in traffic or industrial activity. Overall, the dataset provides up‑to‑date insight for most pollutants but has limited temporal depth for two gases, so city conditions may differ across locations and times not captured by the current rows.

Data notes

The data set for Ghent includes 13 valid measurements and is refreshed regularly, having been Updated within 3 days (last update on 2026‑02‑10 at 18:00 UTC). These figures represent a snapshot of ambient conditions captured by the monitoring network; actual air quality can differ across neighborhoods and change throughout the day. Use this information as an overview rather than a precise location‑by‑location reading.
