Air quality today

The air quality in Yerevan is currently classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 27.44 µg/m³. This figure is derived from 13 valid observations collected by the OpenAQ network. Measurements for PM10 are not available for this reporting period.

The reported values represent the conditions captured at the time of sampling and are provided without additional commentary. The dataset includes a total of 13 measurement points, each contributing to the overall assessment. No other pollutants are highlighted for this interval. The information is presented as received from the monitoring stations and does not include predictive modeling. The values reflect the most recent measurements available from the network. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Yerevan city page pulls data from OpenAQ for five measured pollutants: PM1, PM2.5, relative humidity, temperature and UM003 (particles per cubic centimetre). In total the dataset contains 82 rows contributed by 44 monitoring stations, which works out to roughly two rows per station on average. Freshness is mixed: 13 rows have been updated within the last 30 days, 10 are classified as old, and the majority – 59 rows – are marked unknown, meaning the exact age of those observations cannot be determined. The most recent timestamps across all pollutants are from 2026‑02‑10 20:04 UTC for PM2.5 and 2026‑02‑10 20:00 UTC for the other four variables, placing the newest data about 13 days behind the current date.

Across the five pollutants the numbers show a range of variability. PM2.5 values span from a minimum of 0.0 µg/m³ up to a maximum of 452.37 µg/m³, with a median of 9.625 µg/m³; a recent reading of 27.44 µg/m³ was recorded at the Harutyun Margaryan site. In contrast, PM1 measurements are consistently higher, ranging between 25.16 and 62.40 µg/m³ and clustering around a median of 43.78 µg/m³; the lowest observed PM1 value of 25.16383333206177 µg/m³ comes from Nkarichneri shenq. Relative humidity shows a tighter band, moving from 32.50 % to 52.17 % with a median of 42.33 %, while temperature varies only between 7.75 °C and 9.49 °C, medianing at 8.62 °C. UM003 particle counts range from 1 277.16 to 3 938.76 particles/cm³, centred around a median of 2 607.96 particles/cm³, with the lowest count also recorded at Nkarichneri shenq. These figures illustrate that while some parameters such as humidity and temperature remain relatively stable, particulate matter can exhibit a very wide spread, and the overall dataset includes a mix of recent and older or unclassified observations, so city‑wide conditions may differ by location and time.
