Air quality today
The air quality in Nakhon Ratchasima City Municipality is currently classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 31.8 µg/m³ based on two valid observations reported through OpenAQ.
These measurements indicate that fine particulate matter is the dominant factor influencing today’s air quality assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 Nakhon Ratchasima City Municipality contains six pollutant measurements drawn from a single monitoring location – the Municipal Waste Water Pumping Station. All six common air‑quality constituents are represented: carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulfur dioxide (SO2). The overall freshness of the data is mixed; the most recent reading among all pollutants is from 2026‑02‑10 22:00 UTC (NO2 and PM2.5), while the oldest timestamps date back to 2023‑10‑27 03:00 UTC for PM10 and earlier in 2024‑04‑10 for CO. Three of the six parameters (CO, O3 and SO2) have not been updated since 2024 or earlier, indicating that half of the series are older than a year.
Across the available values there is little variation because each pollutant has only one recorded point. CO sits at 1.3 ppm, NO2 at 0.013 ppm, O3 at 0.072 ppm and SO2 at 0.0 ppm, while the particulate measures are 24.0 µg/m³ for PM10 and 31.8 µg/m³ for PM2.5. The median values equal the minimum and maximum for every pollutant, reflecting the single‑row nature of the data set rather than a distribution over time or space.
Because the coverage is limited to one station, the figures capture conditions only at that specific site and may not represent citywide air quality. The mix of recent (NO2, PM2.5) and older (CO, O3, SO2, PM10) timestamps highlights uneven data freshness, so users should keep in mind that actual concentrations can differ across neighborhoods and change more rapidly than the recorded snapshots suggest.

Data notes
The data shown reflects two valid measurements and is marked as Updated within 3 days, with the latest reading recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a brief view of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in Nakhon Ratchasima City.
