Air quality today

The air quality in Dimitrovgrad today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 23.15 µg/m³ and a PM10 level of 23.48 µg/m³, based on thirty valid observations collected through OpenAQ.

These values reflect the current state of ambient air in the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The open‑air quality feed for Dimitrovgrad currently draws from four monitoring sites and a total of fifty‑seven recent observations. All the standard pollutants measured by OpenAQ are represented: carbon monoxide (CO), nitrogen oxides (NO, NO₂), ozone (O₃), sulfur dioxide (SO₂), particulate matter in several size fractions (PM1, PM2.5, PM4, PM10), as well as basic meteorological variables – humidity, temperature and atmospheric pressure. The most recent data timestamps cluster around 2026‑02‑10 22:28–22:29 UTC, meaning the newest readings for each pollutant are no older than a few hours at the time of writing.

Across the dataset the concentration ranges show considerable variation. CO values span from about 97 µg/m³ up to 650 µg/m³, with a median near 149 µg/m³; the example reading of 127.47 µg/m³ recorded on Patriarh Evtimii St. sits comfortably within that spread. Nitrogen dioxide is often at the detection limit, ranging from 0 to just under 40 µg/m³ and a median of 15.44 µg/m³ – the latest measurement being exactly zero at the same Patriarh Evtimii location. Particulate matter shows tighter bounds: PM10 varies between 0 and 33.6 µg/m³ (median 20.3 µg/m³), while the finer fractions sit in a narrow band of roughly 0–25 µg/m³, with medians around 18‑20 µg/m³; recent values from 4B Bulgaria Boulevard (PM10 17.13 µg/m³, PM1 15.59 µg/m³, PM2.5 16.78 µg/m³) illustrate typical urban background levels.

Humidity readings are the only variable with a markedly skewed distribution – most entries cluster at the low end (minimum and median both 2.11 %), yet a single recent observation reaches 79.72 % at Patriarh Evtimii St., highlighting how local conditions can differ sharply even within the same city. Overall, while the data are fresh and cover all key pollutants, the number of stations is limited to four, so spatial variation may not be fully captured and conditions can change between sites and over short periods.
