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 Szentendre air‑quality record consists of a single monitoring station that reports five separate measurements: PM1 at 26.71 µg/m³, PM2.5 at 41.30 µg/m³, relative humidity at 48.73 %, temperature at 8.37 °C and particle count (UM003) at 1154.44 particles/cm³. All five variables share the same most‑recent observation timestamp of 2026-02-10 20:00 UTC, which falls within the “updated within three days” freshness window indicated by the source.

Because only one row is available, the data set does not show any variation over time or across locations; each pollutant’s minimum, median and maximum values are identical. The reported figures therefore represent a single snapshot rather than a range of conditions. Relative humidity and temperature are provided in percent and Celsius respectively, while the particulate metrics use micrograms per cubic metre for PM1 and PM2.5 and particles per cubic centimetre for UM003.

The uniform timestamp means that the dataset is as fresh as possible given the three‑day update rule, but the lack of multiple rows limits insight into daily fluctuations or spatial differences within Szentendre. Users should keep in mind that air quality can change throughout the day and across neighbourhoods, so this single point in time captures only one momentary state of the city’s atmosphere.

Data notes

The data shown for Szentendre is based on five valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑10T20:00:00+00:00 (Updated within 3 days). This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
