Air quality today
The air quality in Speyer today is classified as Good. The main pollutant identified is PM2.5, with a measured concentration of 3.03 µg/m³ based on three valid observations from OpenAQ data.
Overall conditions meet the criteria for a Good rating despite the presence of fine particles. 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 Speyer includes four measured air‑quality parameters – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and fine particulate matter (PM₂.5). All of these come from a single monitoring location, identified as Speyer‑Nord, so the station count is one while the total number of data rows is four, one for each pollutant.
The timestamps show that three of the four parameters have been refreshed very recently: NO₂, O₃ and PM₂.5 were all last updated on 2026-02-10 17:00 UTC, which falls within the “updated within three days” freshness bucket. In contrast, the NO measurement is older, with its most recent value recorded on 2024-03-11 11:00 UTC, indicating that this particular series has not been refreshed for almost two years.
Because each pollutant currently has only a single reported value, the statistical spread is effectively zero – the minimum, median and maximum are identical for every parameter. The NO reading stands at 1.89595747 µg/m³, NO₂ at 19.0170383 µg/m³, O₃ at 44.30167 µg/m³ and PM₂.5 at 3.029574 µg/m³. This uniformity means there is no observed variability within the dataset itself; any fluctuations in air quality across different parts of Speyer or over time would not be captured by these static figures. Consequently, while the recent updates for most pollutants suggest that current conditions are being tracked, the limited station coverage and the outdated NO data mean the picture remains incomplete and may not reflect localized differences throughout the city.
