Air quality today

The air quality in Debrecen is classified as USG today. The primary pollutant identified is PM2.5, with a measured concentration of 49.39 µg/m³. In addition, the PM10 level is recorded at 22.0 µg/m³ based on twelve valid observations.

Data are shown via OpenAQ and reflect the current monitoring results for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Debrecen contains measurements from ten monitoring stations and a total of fifty individual rows. It covers the full set of pollutants recorded by OpenAQ in this city: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃) – although no recent O₃ values appear in the current rows, fine particulate matter (PM1, PM2.5, PM10), sulfur dioxide (SO₂) – also without fresh entries, relative humidity, temperature, and particle count (UM003). Most of the variables have data that were last updated on 2026‑02‑10 at 20:00 UTC, indicating a very recent snapshot for those parameters. The exception is CO, whose newest record dates from 2024‑09‑20 21:00 UTC, making it considerably older than the rest of the series.

Across the available pollutants the observed values show a broad spread. For particulate matter, PM10 ranges from about 0.56 to 26.81 µg/m³ with a median of 19 µg/m³; PM2.5 varies between roughly 1.0 and 49.39 µg/m³, median 13.68 µg/m³; and PM1 spans 0.38 to 32.36 µg/m³, median 11.79 µg/m³. Relative humidity values lie between 28.4 % and 62.1 %, with a typical level near 48.8 %; temperature records cover 10.16 °C up to 24.80 °C, centering around 21.1 °C. Particle concentration (UM003) is recorded from about 464 to 1441 particles/cm³, median roughly 1174. CO values are higher, ranging from 240.85 to 1274 µg/m³ with a median of 545.5 µg/m³.

The coverage is uneven: while most pollutants have six or seven recent rows, CO and the older categories have only four rows each, and several parameters such as O₃ and SO₂ lack any fresh entries in this extract. Consequently, the dataset provides a detailed recent picture for particulate matter, humidity, temperature and particle count, but offers limited and outdated information for gases like CO, NO₂ (which has three recent rows) and none for ozone or sulfur dioxide. Users should keep in mind that conditions can differ across neighborhoods and times not captured by the current rows.

Data notes

The dataset for Debrecen contains twelve valid measurements and is marked as Updated within 3 days, with the most recent data recorded on 2026‑02‑10 at 20:00 UTC. This snapshot reflects conditions captured by the monitoring network at that time; however, air quality can vary across different neighborhoods and throughout the day, so values may not represent every location or moment in the city.
