What the data includes

The Cerisé air‑quality record draws on a single monitoring site that contributed five separate pollutant readings. All five standard pollutants tracked by OpenAQ are represented: nitrogen monoxide (NO) at 38.1 µg/m³, nitrogen dioxide (NO₂) at 5.3 µg/m³, ozone (O₃) at 61.7 µg/m³, particulate matter 10 µm or less (PM10) at 2.7 µg/m³ and fine particulate matter 2.5 µm or less (PM2.5) at 2.3 µg/m³. Each value comes from the same source, Alençon Météo‑France.

The timestamps show a mixed picture of data freshness. The NO measurement is dated 2024‑03‑11 07:00 UTC, making it the oldest entry in the set, while the remaining four pollutants were all updated on 2026‑02‑10 15:00 UTC, which falls within the last three days and therefore counts as recent. Because only one station supplies data, there is no spatial spread across Cerisé; conditions can differ in other neighbourhoods or at times not captured by these five rows.

Overall the dataset is very narrow: a single location provides identical values for each pollutant (no range or variability), with the median equal to the minimum and maximum for every metric. Four of the five readings are fresh, but the NO figure remains over two years old, highlighting an uneven temporal coverage across pollutants. Users should keep in mind that this snapshot reflects one point in the city at specific moments rather than a comprehensive, city‑wide picture.
