Air quality today
The air quality in Mariánské Radčice today falls into the Moderate category. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 20.9 and a PM10 reference value of 22.7, based on five valid observations collected via OpenAQ.
These figures reflect the current assessment without implying any trend or cause. 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 air‑quality record for Mariánské Radčice draws on six individual measurement rows, each providing a single pollutant reading from the Lom monitoring site. All six key pollutants—nitric oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulfur dioxide (SO₂)—are represented, giving a full snapshot of the city’s main atmospheric constituents.
The data are fairly recent for most compounds: the latest updates for NO₂, O₃, PM₁₀, PM₂.₅ and SO₂ were recorded on 2026‑02‑10 at 14:00 UTC, while the NO value dates back to 2024‑03‑11 at 10:00 UTC. This means that five of the six pollutants have been refreshed within the past three days, whereas the nitric oxide reading is older by almost two years. Across the dataset the median values are identical to the minimum and maximum for each pollutant, indicating that only a single measurement per row is available rather than a range of observations. Specifically, NO sits at 1.5 µg/m³, NO₂ at 8.0 µg/m³, O₃ at 47.7 µg/m³, PM₁₀ at 22.7 µg/m³, PM₂.₅ at 20.9 µg/m³ and SO₂ at 4.0 µg/m³.
Because the station coverage consists of a single site (Lom) reporting one value per pollutant, spatial variation within Mariánské Radčice is not captured in this set. The dataset therefore reflects point‑specific conditions rather than city‑wide averages, and any changes that occur outside the Lom location or after the most recent timestamps will not be reflected here.

Data notes
The data shown for Mariánské Radčice is based on five valid measurements and was updated within three days, with the latest refresh recorded at 2026‑02‑10 14:00 UTC. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and change throughout the day, so values may not represent the entire city at any given moment.
