Air quality today

The air quality in Proboštov today falls into the USG category according to the latest assessment. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 43.4 µg/m³, based on five valid readings collected for this location.

Data are shown via OpenAQ and reflect the current conditions without additional interpretation. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 Proboštov dataset contains six measured variables: PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003. All of these come from a single monitoring row, so the city’s air‑quality picture is based on one outdoor sensor location.

Freshness varies across the pollutants. The most recent readings for PM1, PM2.5, relative humidity, temperature and UM003 were all recorded on 2026-02-10 at 18:00 UTC, meaning they are less than three days old. In contrast, the latest PM10 value dates back to 2025-01-13 at 23:00 UTC, making it over a year old and the only “old” entry in the set.

The numeric values show no spread because each pollutant has a single reported measurement. PM1 is recorded at 25.81 µg/m³, PM10 at 62.64 µg/m³ and PM2.5 at 43.40 µg/m³. Relative humidity stands at 51.55 % and temperature at 2.77 °C. The particle concentration UM003 is 4 220.68 particles per cubic centimetre. Because there is only one observation per variable, the median, minimum and maximum are identical.

Overall, the data coverage is limited to a single station, with five of six variables updated within the last three days while PM10 remains outdated. This means that while recent snapshots exist for most pollutants, the picture for coarse particles (PM10) may not reflect current conditions, and city‑wide variations cannot be captured from this lone source.
