The air quality in Halle today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 1.0 µg/m³, based on five valid observations.
Overall conditions meet the Good category criteria with no additional pollutants reported. 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 Halle in Flemish Brabant contains measurements from a single monitoring site that contributed five rows of data. All five rows are recent, with the most recent timestamp recorded on 2026-02-10 19:00 UTC, which falls within the three‑day freshness window used by OpenAQ.
Five pollutants are reported: PM1 at 0.30000000074505806 µg/m³, PM2.5 at 1.0 µg/m³, relative humidity at 89.75 %, temperature at 9.949999809265137 °C, and UM003 particles at 206.0 particles/cm³. For each pollutant the minimum, median and maximum values are identical across the five rows, indicating no observed variation in this snapshot of data. Consequently, the inter‑percentile range (10th to 90th percentile) is also a single point for every parameter.
Because only one station contributes data, spatial coverage within Halle is limited; conditions elsewhere in the city may differ from those captured at Groene Longen _Zuster Bernardastraat. The uniform timestamps show that all measurements were taken at the same moment, so temporal depth is absent – there are no older or future readings to illustrate trends over time. This means the current picture reflects a single instant rather than a broader pattern.
In summary, the available data set includes five pollutants measured at one location, with five recent rows all sharing the same timestamp and identical values for each parameter. The lack of variation across rows and the reliance on a solitary monitoring point suggest that while the information is fresh, it offers only a narrow view of Halle’s air quality at that specific time.
