Air quality today

The air quality in South Dublin is classified as Good today. The primary pollutant measured is PM2.5 (fine particles).

Measurements from nine valid monitoring points show a PM2.5 reference value of 2.33 and a PM10 reference value of 3.57. Data are shown via OpenAQ.

What the data includes

South Dublin’s open‑air quality feed currently includes four measured pollutants – nitrogen dioxide (NO₂), particulate matter up to 10 µm (PM₁₀), fine particulate matter up to 2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). The dataset comprises fifteen recent rows of sensor readings, with nine entries recorded within the last three days and six older records that date back further than three days. Across all pollutants the most recent timestamp is 2026‑02‑10 13:00 UTC, which applies to NO₂, PM₁₀ and PM₂.₅; SO₂’s latest value is from 2024‑05‑30 08:00 UTC, indicating a longer gap for that gas.

The values show a modest spread for the particulate metrics. For PM₁₀ the median concentration is 2.17 µg/m³, with individual readings ranging from essentially zero up to 14.14 µg/m³; the 10th and 90th percentiles sit at 0.87 and 9.91 µg/m³ respectively. PM₂.₅ displays a similar pattern: its median is 1.70 µg/m³, the minimum recorded value is 1.07 µg/m³ and the maximum reaches 9.09 µg/m³, while the 10th and 90th percentiles are 1.07 and 7.06 µg/m³. NO₂ values are higher, with a median of 27.55 µg/m³ and both the minimum and maximum recorded at 13.64 µg/m³ and 27.55 µg/m³ respectively; the lower‑decile sits near 16.42 µg/m³. SO₂ is the least current, showing a median of –1.0 µg/m³ (the sensor reports negative values as placeholders) and a maximum of about 12.07 µg/m³, but only six older rows contribute to its record.

Overall the dataset gives a fairly recent picture for particulates and NO₂, while SO₂ coverage is sparse and dated. Because the data come from a limited number of monitoring points – all located at Dublin Tallaght Old Bawn Road – conditions can differ across other parts of South Dublin and may change between updates.

Data notes

The data shown reflects nine valid measurements and is updated within 3 days, with the latest refresh recorded at 2026‑02‑10T13:00:00+00:00. These readings provide a recent snapshot of South Dublin’s air quality but should be interpreted as an overview only; conditions can differ across neighbourhoods and change throughout the day.
