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
The air‑quality record for Épernay currently draws from a single monitoring site, the Rempart Perrier station, which supplies data on four pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter up to 10 µm (PM₁₀) and fine particulate matter up to 2.5 µm (PM₂.₅). Because there is only one row of observations, the dataset does not capture spatial variation across the city; it reflects conditions at that specific location.
The most recent NO reading dates back to 2024‑03‑11 08:00 UTC and shows a concentration of 207.3 µg/m³. The NO₂ value is much newer, recorded on 2026‑02‑10 15:00 UTC at 12.6 µg/m³. Both PM₁₀ and PM₂.₅ were last updated on 2026‑02‑09 03:00 UTC, with concentrations of 11.6 µg/m³ and 8.3 µg/m³ respectively. All four pollutants have a single reported value, so the minimum, median and maximum are identical for each – there is no observed spread in the data.
Because the dataset contains only one recent entry for three of the four pollutants (within the past week) and an older NO measurement from more than two years ago, the overall freshness is mixed. The newer timestamps suggest that particulate matter and NO₂ are being refreshed regularly, while the NO figure remains outdated. Consequently, any snapshot of Épernay’s air quality should be understood as limited to this lone site and its varying update cadence; conditions elsewhere in the city may differ from what these single‑point values convey.

Data notes
The dataset for Épernay includes three valid measurements and is refreshed regularly, having been updated within the past three days (last update 2026‑02‑10T15:00:00+00:00). These values represent a snapshot of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so this information may not reflect localized or moment‑to‑moment variations.
