What the data includes

The Krumovgrad air‑quality feed currently draws from a single monitoring site – OU Podrumche – which supplies seven rows of data, one for each measured pollutant. The dataset includes humidity, PM1, PM10, PM2.5, PM4, pressure and temperature, so the full suite of common atmospheric variables is represented.

All of the latest observations were recorded at the same moment, 2026‑02‑10 14:52 UTC, and each pollutant’s entry lists identical minimum, median and maximum values, indicating that only one recent measurement is available for every parameter. Humidity stands at 79.71 %, temperature is a chilly 1.09 °C, pressure reads 972.36 hPa, while the particulate matter concentrations are tightly clustered: PM1 at 14.88 µg/m³, PM2.5 at 15.91 µg/m³, PM4 at 16.05 µg/m³ and PM10 at 16.12 µg/m³. Because there is just a single data point per pollutant, the spread (p10‑p90) is effectively zero, so no variability can be inferred from this snapshot.

With only one station contributing, spatial coverage across Krumovgrad is limited; conditions may differ in other neighborhoods or at different times of day. The timestamps are fresh – all updated within the last three days – but the lack of historical rows means trends cannot be assessed here. Users should keep in mind that while the current values give a precise picture for OU Podrumche at the recorded moment, they do not capture the full temporal or geographic diversity of air quality across the city.

Data notes

The data shown for Krumovgrad reflects seven valid measurements and was updated within three days, with the latest update recorded at 2026‑02‑10T14:52:00+00:00. This snapshot provides a current view of ambient air quality but should be interpreted as a brief overview; conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in this single set of readings.
