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 Ridderkerk air‑quality dataset contains five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM10) and particulate matter 2.5 µm or smaller (PM2.5). All data come from a single monitoring location, Ridderkerk‑Hogeweg, so the station count is one row per pollutant.
Freshness varies across the suite. The most recent readings for NO₂, PM10 and PM2.5 were recorded on 2026‑02‑10 at 21:00 UTC, meaning those three pollutants have data that are less than a week old. In contrast, the latest entries for NO and O₃ date back to 2024‑03‑25 at 22:00 UTC, which classifies them as “old” in the source system.
The numeric values currently available show a very narrow range because each pollutant has only one reported measurement. For NO₂ the single value is 52.7 µg/m³; for PM10 it is 16.0 µg/m³; and for PM2.5 it is 10.4 µg/m³. Both NO and O₃ are listed with a placeholder of –999.0 µg/m³, indicating that no valid measurement exists for those compounds at this site.
Because the dataset relies on just one monitoring point, spatial variation within Ridderkerk cannot be captured; conditions may differ in other neighborhoods or at different times of day. Moreover, the presence of outdated or missing values for NO and O₃ means that a complete picture of all five pollutants is not currently available, and any interpretation should consider these gaps.
