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 dataset for Södertälje currently contains three pollutant records collected from a single monitoring site at Södertälje Turingegatan 26. All three measurements – nitrogen dioxide (NO₂), particulate matter ≤10 µm (PM₁₀) and particulate matter ≤2.5 µm (PM₂.₅) – were last updated on 2026‑02‑10 at 18:00 UTC, which places them well within the “updated within 7 days” freshness window.
Because the data come from only one station, each pollutant shows a single value that serves as both the minimum, median and maximum for the reporting period. NO₂ is recorded at 84.51 µg/m³, PM₁₀ at 11.2009993 µg/m³ and PM₂.5 at 5.0138 µg/m³. The identical min‑med‑max figures indicate that no variability was captured across the sampling interval; the reported percentiles (10th and 90th) match the same numbers, confirming a lack of spread in the available observations.
With just one location providing data for all three pollutants, the coverage is limited to conditions at Turingegatan 26 and does not reflect possible differences elsewhere in Södertälje. The timestamps are recent, but because there is no historical depth or multiple sites, the dataset cannot show temporal trends or spatial gradients within the city. Users should keep in mind that air‑quality can change across neighborhoods and over time, so these snapshot values represent a narrow view of the current situation at the single monitoring point.

Data notes
The data shown for Södertälje is based on three valid measurements and was updated within 3 days, with the latest reading recorded at 2026‑02‑10 18:00 UTC. While this snapshot reflects current conditions at the monitoring site, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
