This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Bayan Nurun today is classified as Good. The primary pollutant identified is PM2.5. The most recent PM2.5 measurement is 0.0055 µg/m³, derived from four valid observations. This concentration falls within the range associated with the Good category. The reported value of 0.0055 µg/m³ represents a low measured concentration for fine particles. All four readings were consistent with one another, reinforcing the reliability of the assessment. No PM10 data are available for this assessment.
Data are shown via OpenAQ, which aggregates the four measurements used in this evaluation. The dataset confirms the Good rating and the identification of PM2.5 as the dominant pollutant. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
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 dataset for Bayan Nurun pulls together five recent observations recorded at a single monitoring site, all captured on 2026‑01‑26 04:00 UTC. Every pollutant listed below is represented in each of those rows, and the timestamps place the entire collection within the last 30 days, with no older or unknown entries.
The available measurements include PM1 at 0.0 µg/m³, PM2.5 at 0.005500000218550364 µg/m³, relative humidity at 40.21291671858893 %, temperature at –2.105444431801637 °C, and UM003 particle concentration at 99.81211094326443 particles/cm³. For each parameter the minimum, median and maximum values are identical, indicating that the five records do not show any variation over the sampled period. This uniformity suggests the data reflect a single snapshot rather than a continuous time series.
Because the information comes from just one station, spatial coverage across Bayan Nurun is limited; conditions elsewhere in the city may differ from those recorded at this location. Nonetheless, the data are fresh, with the most recent update occurring less than a month ago, and every pollutant is covered in the same set of rows. The snapshot shows a relatively cool environment (just below zero degrees Celsius) with moderate humidity around 40 % and a low particulate load for both PM1 and PM2.5. While the dataset provides a clear, up‑to‑date picture of the measured site, the lack of variability and the single‑station scope mean it should be interpreted as a point‑in‑time reference rather than a comprehensive view of city‑wide air quality.
