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 Hook of Holland draws from a single monitoring site, Hoek v. Holland-Berghaven, which supplies data on six key pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulphur dioxide (SO₂). Because only one row of measurements is available, the spatial coverage across the city is limited to this location.
The most recent observations are fairly fresh for five of the six compounds, all updated on 2026‑02‑10 at 21:00 UTC. NO₂ shows a median concentration of 54.6 µg/m³, while PM10 and PM2.5 register 14.3 µg/m³ and 9.9 µg/m³ respectively; SO₂ is measured at 2.2 µg/m³. Ozone data are older, last refreshed on 2024‑09‑10 at 22:00 UTC with a single value of 57.2 µg/m³, and NO remains outdated from 2024‑03‑25 at 22:00 UTC, recorded as –999.0 µg/m³ indicating an unavailable reading.
Across the dataset the range for each pollutant is effectively zero because only one measurement exists per parameter; the minimum, median and maximum values are identical. This uniformity highlights that the current snapshot does not capture variability over time or across different parts of Hook of Holland. Consequently, while the recent timestamps suggest up‑to‑date information for most pollutants, the single‑site coverage means city‑wide conditions may differ from what is reported here.
