Air quality today
The air quality in Aarschot today is classified as Good. The primary pollutant measured is PM2.5 (fine particles). According to the latest data shown via OpenAQ, the PM2.5 reference value stands at 2.5905 and the PM10 reference value is 4.3, based on four valid measurements.
These figures indicate that particulate concentrations are within the range associated with a Good rating for this location. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 dataset for Aarschot contains five recorded pollutant measurements drawn from a single monitoring location (code 42N035 – AARSCHOT). All five common urban pollutants are represented: nitrogen dioxide, ozone, particulate matter ≤10 µm, particulate matter ≤2.5 µm, and sulfur dioxide. For four of the pollutants—NO₂, O₃, PM₁₀ and PM₂.₅—the most recent reading was logged on 2026‑02‑10 at 18:00 UTC, which falls within the “updated within three days” freshness bucket. Sulfur dioxide is the outlier; its only entry dates back to 2020‑01‑24 at 01:00 UTC and is flagged as old data.
Because each pollutant has a single recorded value, the statistical spread is effectively zero: the minimum, median and maximum are identical for every compound. NO₂ registers 11.0 µg/m³, O₃ shows 59.5 µg/m³, PM₁₀ measures 4.3 µg/m³, PM₂.₅ records 2.5905 µg/m³, and SO₂ is reported at 0.0 µg/m³. This uniformity means the dataset does not capture variability over time or across different parts of the city.
The overall picture is one of limited temporal depth and spatial coverage. While four pollutants have recent entries, the single‑station setup provides only a snapshot rather than a comprehensive view of air quality throughout Aarschot. The older sulfur dioxide reading further highlights gaps in continuous monitoring. Consequently, conditions can differ across neighborhoods and moments that are not reflected in this narrow set of data.
