Air quality today

The air quality in Rotselaar today is classified as Good. The primary pollutant measured is PM2.5, with a recorded concentration of 7.09 µg/m³ based on five valid observations from OpenAQ data.

Overall conditions meet the criteria for a Good rating, and the available measurements indicate that fine particulate levels are within this category’s range. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Rotselaar air‑quality feed contains five recent observations from a single monitoring site, covering five key variables: PM1, PM2.5, relative humidity, temperature and particle count (UM003). All measurements were recorded at the same moment – 2026-02-10 19:00 UTC – which meets the “updated within three days” criterion, so the data are as fresh as currently available for this city.

For each pollutant the dataset shows a single value that also serves as the minimum, median and maximum. PM1 is reported at 4.73 µg/m³, while fine particulate matter (PM2.5) measures 7.09 µg/m³. The relative humidity reading stands at 61.12 %, and the ambient temperature is 13.33 °C. Particle concentration measured by the UM003 sensor is 946.61 particles per cm³. Because there is only one row per variable, the inter‑quartile range (p10 to p90) collapses to the same figure, indicating no observed spread in this snapshot.

The coverage is limited: only one station contributes data for Rotselaar, so spatial variation across the municipality cannot be captured here. Nevertheless, the timestamp uniformity shows that every pollutant was logged simultaneously, providing a consistent picture of conditions at that specific time. Users should keep in mind that air quality can differ across neighborhoods and over short periods, and the current dataset reflects just this single moment rather than longer‑term trends.
