Air quality today

The air quality in Khan Chbar Ampov today falls within the USG category. The primary pollutant identified is PM2.5, based on a set of twenty valid measurements collected for this location.

The latest data show a PM2.5 concentration of 52.53 µg/m³. This figure reflects the current monitoring results displayed via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Khan Chbar Ampov air‑quality feed draws from three monitoring sites that together contributed 70 recent observations. All five measured pollutants – PM1, PM2.5, relative humidity, temperature and UM003 (particle count) – are reported with a latest timestamp of 2026‑02‑10 19:00 UTC, meaning the data were refreshed within the past three days for every parameter.

PM1 values span from essentially zero up to about 45.5 µg/m³, with a median near 19.8 µg/m³ and the middle 80 % of readings falling between roughly 0.2 and 41.7 µg/m³. PM2.5 shows a broader spread, ranging from just under 1 µg/m³ to almost 69 µg/m³; its median is 31.2 µg/m³ and the inter‑decile range runs from about 1.6 to 57.7 µg/m³. Relative humidity measurements vary between 33 % and 69 %, centering on a typical value of 47 %. Temperature readings cover a modest band from roughly 25.8 °C to 34.2 °C, with a median of 29.8 °C. The UM003 particle count is the most variable, moving from about 181 particles/cm³ up to 3 556 particles/cm³; half of the observations sit near 1 107 particles/cm³ and the 10th‑90th percentile stretches from 214 to nearly 2 998 particles/cm³.

Because each pollutant has exactly 14 recent samples per station, coverage is evenly distributed across parameters but limited in depth – only three sites contribute data for Khan Chbar Ampov. The freshness of all timestamps indicates that the snapshot reflects conditions as of early February 2026, yet the relatively small number of stations means spatial variations within the district may not be fully captured. Consequently, while the dataset provides a current picture of key air‑quality metrics, it represents a concise sampling rather than exhaustive citywide monitoring.
