Air quality today

The air quality in Changchun City is currently classified as Unhealthy. The primary pollutant identified is PM2.5, with a measured concentration of 98.04 µg/m³ based on nine valid observations reported through OpenAQ.

PM2.5 levels are the main driver of today’s rating, and no other pollutants have been listed for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Changchun City pulls information from four monitoring stations, each providing a row of observations across the listed pollutants. All nine measured compounds—CO, NO2, O3, PM1, PM10, PM2.5, RELATIVEHUMIDITY, SO2 and TEMPERATURE—are represented, although temperature does not appear in the recent summary values. The most up‑to‑date records are from 2026-02-10 17:00 UTC for PM2.5, PM1, relative humidity and the associated stations, while the remaining six pollutants (CO, NO2, O3, PM10, SO2) were last refreshed on 2021-08-09 11:00 UTC, making those entries over two years old.

Across the four stations, PM2.5 values range from a low of 22.0 µg/m³ to a high of 98.04 µg/m³, with a median around 48.15 µg/m³; the inter‑decile spread (10th to 90th percentile) runs from 22.6 to 90.32 µg/m³, indicating considerable variability within the city. PM1 shows a narrower band, from about 42.33 to 55.52 µg/m³ and a median of 48.93 µg/m³, suggesting more consistent fine‑particle concentrations at the sites that report it. Relative humidity measurements are clustered between roughly 34.5 % and 37.0 %, with a median near 35.77 %, reflecting fairly stable moisture conditions during the latest sampling period.

In contrast, the older data for CO, NO2, O3, PM10 and SO2 each present single‑point values: CO is consistently recorded at 700 µg/m³, NO2 peaks at 26 µg/m³, O3 at 118 µg/m³, PM10 at 57 µg/m³ and SO2 reaches 5 µg/m³. Because these figures stem from the same timestamp in 2021, they do not capture any recent changes or spatial differences that may exist now. Consequently, while the dataset offers a clear snapshot of fine‑particle and humidity conditions for early February 2026, it provides limited insight into current levels of several key gases, underscoring that city air quality can still vary by location and time beyond what is captured here.

Data notes

The data shown reflects nine valid measurements and is marked as Updated within 3 days, with the latest reading recorded at 2026‑02‑10T17:00:00+00:00. This snapshot provides a current view of air quality across Changchun City, but conditions can differ by specific neighborhoods and times of day, so local variations may not be captured in these aggregate figures.
