Air quality today

The air quality in Nanguan District, Jilin, is currently classified as Unhealthy. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 112.54 µg/m³ based on five valid readings.

Data are shown via OpenAQ and reflect the latest available observations for this location. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Nanguan District pulls information from 23 recorded rows across 4 monitoring sites and covers ten measured variables: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of 1 µm (PM₁), 2.5 µm (PM₂.5), and 10 µm (PM₁₀) size fractions, sulfur dioxide (SO₂), relative humidity, temperature and a field labeled UM003. The most recent observations are from 2026‑02‑10 17:00 UTC for PM₂.5, PM₁, and relative humidity, while the remaining seven pollutants were last updated on 2021‑08‑09 11:00 UTC, indicating that half of the parameters rely on data that is more than two years old.

Across the recent entries, PM₂.5 shows a wide spread, ranging from a low of 19.0 µg/m³ to a high of 112.54 µg/m³, with a median value of 22.0 µg/m³ and the 90th percentile near 85.38 µg/m³. By contrast, CO values are clustered between 600 and 800 µg/m³ (median 700 µg/m³), and NO₂ varies from 9 to 23 µg/m³ (median 18 µg/m³). Ozone measurements sit in a narrow band of 127‑136 µg/m³, while PM₁₀ ranges from 29 to 67 µg/m³ (median 47 µg/m³). SO₂ is constant at 4 µg/m³ across all records. The single recent reading for PM₁ reports exactly 60.44 µg/m³, and relative humidity is recorded as 33.07 %.

These figures illustrate that the dataset provides a fairly comprehensive chemical profile but with uneven temporal coverage: three‑quarter of the pollutants are represented only by older data, while only PM₂.5, PM₁ and humidity have been refreshed within the past few days. Consequently, while the range of values gives an overview of air quality conditions in Nanguan District, users should keep in mind that many parameters may not reflect current levels and can vary across different locations and times within the district.

Data notes

The data shown for Nanguan District is based on five valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T17:00:00+00:00. This snapshot reflects conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the district.
