Air quality today
The air quality in Port‑Jérôme‑sur‑Seine today is classified as Good. The primary pollutant measured is PM10.
According to OpenAQ, the dataset includes four valid measurements taken today, each indicating PM10 concentrations near the reference level of 2.2 µg/m³. All values are reported through the OpenAQ platform. The Good rating reflects that measured pollutants are within limits defined for this classification. With four observations, the dataset provides a reliable snapshot of current conditions. No other pollutants exceeded the thresholds for this assessment. The PM10 reference value of 2.2 µg/m³ is used as a benchmark for comparison in the reporting system daily monitoring. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
Port‑Jérôme‑sur‑Seine’s OpenAQ feed contains six measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and sulphur dioxide (SO₂). All data come from a single monitoring station, so the dataset consists of six rows, one for each pollutant. The most recent measurements are fairly fresh for four of the pollutants: CO was last recorded on 2026‑02‑06 11:00 UTC, NO₂ on 2026‑02‑10 15:00 UTC, and both PM₁₀ and SO₂ also on 2026‑02‑10 15:00 UTC. NO’s latest entry dates back to 2024‑03‑11 09:00 UTC, while O₃ is the oldest value in the set, recorded on 2018‑08‑23 12:00 UTC. This mix of timestamps means that while most pollutants have up‑to‑date readings within the past week, two of them rely on data that are months or years old.
The numeric values show no variation within each pollutant’s record because only a single observation is available per row. CO registers 141.0 µg/m³, NO 2.0 µg/m³, NO₂ 5.3 µg/m³, O₃ 47.4 µg/m³, PM₁₀ 2.2 µg/m³ and SO₂ 3.9 µg/m³; the minimum, median and maximum are identical for each. Because there is just one measurement per pollutant, the dataset cannot illustrate any spread or trend over time, and the lack of multiple stations means spatial differences across the city are not captured.
Overall, the data provide a snapshot of six key air‑quality components at a single location, with four pollutants offering recent values and two relying on older records. Users should keep in mind that conditions can differ elsewhere in Port‑Jérôme‑sur‑Seine and that the current figures represent only the moments when each sensor last reported.

Data notes
The data shown are based on four valid measurements and have been refreshed recently, with the latest update recorded on 2026‑02‑10 at 15:00 UTC; this means the information is updated within three days. Please note that air quality can vary across different neighborhoods and times of day within Port‑Jérôme‑sur‑Seine, so the values presented represent a snapshot rather than a constant condition throughout the entire city.
