Air quality today
The air quality in Charleville‑Mézières is assessed as Good today. The main pollutant identified is PM10, and the measured concentration of this coarse particle fraction is 2.5 µg/m³ based on three valid observations.
Data are shown via OpenAQ and reflect the current monitoring results for the city. 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
The Charleville‑Mézières air‑quality record currently contains four pollutant measurements collected from a single monitoring location, giving a total of four data rows. The dataset includes nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter 10 µm or smaller (PM10). All values are expressed in micrograms per cubic metre (µg/m³).
The most recent observations were uploaded on 2026‑02‑10 at 15:00 UTC for NO₂, O₃ and PM10, indicating that the majority of the data is fresh within the last three days. The NO reading, however, dates back to 2024‑03‑11 at 08:00 UTC and is flagged as “old data,” so it does not reflect current conditions. For each pollutant the reported minimum, median and maximum are identical, showing that only a single measurement is available per substance: NO = 2.2 µg/m³, NO₂ = 4.9 µg/m³, O₃ = 65.5 µg/m³ and PM10 = 2.5 µg/m³. The percentile values (p10 and p90) match these figures as well, confirming the lack of variability in the present sample.
Because the dataset relies on a single station, spatial coverage across Charleville‑Mézières is limited; variations that might occur elsewhere in the city or at different times are not captured here. The overall picture is one of very recent data for three pollutants and an older snapshot for NO, with each pollutant represented by only one measurement point. Users should keep in mind that air‑quality conditions can differ across neighborhoods and over time, and the current dataset provides a narrow but up‑to‑date view for most of the listed contaminants.
