Air quality today

The air quality in Liverpool today is classified as Good. The primary pollutant measured is PM2.5, fine particulate matter.

Measurements show a PM2.5 concentration of 9.0 µg/m³ and a PM10 level of 14.0 µg/m³ based on five valid readings collected via OpenAQ. The data reflect conditions recorded on 2026-02-14 09:00 UTC. A total of five valid measurements were used to determine the reported values, ensuring a reliable assessment for this period. Data are shown via OpenAQ, which aggregates observations from multiple monitoring stations across the city. These figures represent the current ambient concentrations of particulate matter for Liverpool as measured today. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Liverpool pulls information from 11 individual measurement rows collected at two monitoring sites, with the most recent updates recorded on 2026‑02‑10 20:00 UTC for most pollutants. Six of the rows are flagged as “unknown” in terms of freshness, meaning their timestamps are not available, while five have been updated within the last seven days; no data are marked as older than three days. The pollutants that appear in the feed are nitrogen dioxide (NO2), ozone (O3), sulphur dioxide (SO2), particulate matter of three size fractions (PM1, PM2.5 and PM10), relative humidity and temperature.

For the particulate metrics there is a clear spread: PM10 values range from 14 µg/m³ to 65 µg/m³ with a median around 40 µg/m³, while PM2.5 varies between 9 µg/m³ and 52 µg/m³ with a median near 31 µg/m³. The single‑point readings for the gases are all identical across the available rows – NO2 is recorded at 25 µg/m³, O3 at 28 µg/m³ and SO2 at 2 µg/m³ – reflecting that only one recent observation exists for each of these pollutants. In contrast, PM1, relative humidity and temperature have no timestamped values; the dataset lists a single measurement for each but marks the update time as unknown.

Overall the coverage is uneven: particulate matter has multiple recent observations and a measurable range, whereas the gas‑phase pollutants are represented by a solitary, static value and the meteorological variables lack any fresh timestamps. Because many rows are missing date information, the picture of Liverpool’s air quality is limited to the most recent snapshot from early February 2026 and may not capture variations across different neighbourhoods or times of day.

Data notes

The data shown reflects five valid measurements and is Updated within 3 days, with the most recent reading recorded at 2026‑02‑10T20:00:00+00:00. This snapshot provides a current view of Liverpool’s air quality but should be interpreted as a brief moment in time; conditions can differ across neighbourhoods and fluctuate throughout the day.
