Air quality today

The air quality in Roosendaal today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 21.74 µg/m³ based on ten valid observations reported through OpenAQ.

Data indicate that the current conditions are described by the Moderate category with PM2.5 as the main contaminant, and the recorded value reflects the most recent sampling set. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Roosendaal air‑quality dataset contains five measured pollutants – PM1, PM2.5, relative humidity, temperature and UM003 (particle count). All ten rows of data come from a single monitoring station, and each pollutant’s most recent reading was recorded on 2026-02-10 at 22:00 UTC, which falls within the “updated within 7 days” freshness window. Because the data are all from one location, they give a detailed snapshot for that spot but do not capture variation across different neighbourhoods in Roosendaal.

PM1 values range from about 4.3 to 14.2 µg/m³, with a median of roughly 9.2 µg/m³; PM2.5 spans 7.7 to 21.7 µg/m³ and has a median near 14.7 µg/m³, indicating that the larger particles tend to be present at higher concentrations than the finer fraction. Relative humidity stays tightly clustered between 64.6 % and 65.1 %, with a median of 64.85 %; temperature is similarly narrow, varying from 12.42 °C to 12.59 °C and centering around 12.50 °C. The UM003 particle count shows the widest spread, from about 448 to 2 276 particles per cm³, with a median of roughly 1 362, suggesting considerable short‑term fluctuation in overall aerosol load.

Overall, the dataset is fresh and internally consistent, but its coverage is limited to one monitoring point and ten recent rows. Consequently, while the numbers provide a clear picture of current conditions at that specific site, they do not reflect possible differences across other parts of Roosendaal or longer‑term trends. Users should keep in mind that air quality can change with location and time, and this snapshot represents only the latest measurements from the single available sensor.

Data notes

The dataset for Roosendaal includes ten valid measurements and is refreshed regularly, having been updated within the past three days (last update 2026‑02‑10T22:00:00+00:00). These values represent a snapshot of conditions at specific monitoring points; actual air quality can differ across neighbourhoods and change throughout the day. Use this information as an indicative overview rather than a precise, city‑wide reading.
