Air quality today

The air quality in Roi Et is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).

Measurements from six valid observations show a PM2.5 concentration of 21.8 µg/m³ and a PM10 level of 44.0 µg/m³. These values are presented through OpenAQ data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Roi Et draws on seven measurement rows collected at two monitoring sites, all supplied through OpenAQ. Six of the rows have been refreshed within the past week, while one row lacks a recent timestamp and is classified as unknown, meaning that the most current picture relies mainly on data updated on 2026-02-10 22:00 UTC.

All six standard pollutants are represented in the dataset. For fine particulate matter (PM2.5) the values range from a low of 8.6 µg/m³ to a high of 21.8 µg/m³, with a median of 15.2 µg/m³ and the 10th‑percentile at 9.92 µg/m³ and the 90th‑percentile at 20.48 µg/m³. Coarse particles (PM10) show a single reported figure of 44.0 µg/m³, which is both the minimum and maximum observed value. Carbon monoxide (CO) is recorded at a constant 0.6 ppm across its sole recent entry, while nitrogen dioxide (NO2) registers as 0.0 ppm, ozone (O3) as 0.028 ppm, and sulfur dioxide (SO2) as 0.001 ppm, each with no variation in the available data.

The coverage is uneven: PM2.5 benefits from two recent rows, giving a sense of its spread, whereas the other pollutants are represented by only one fresh measurement each. Because most timestamps cluster on the same update moment, the dataset captures conditions at a single point in time rather than continuous trends. Consequently, while the figures provide a snapshot of current concentrations across the city’s monitoring locations, they do not reflect possible fluctuations that may occur later in the day or at other sites not captured by the limited rows.

Data notes

The data shown for Roi Et is based on six valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T22:00:00+00:00. This snapshot reflects conditions measured at specific monitoring points; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
