Air quality today

The air quality in Nong Samet is classified as USG today. The primary pollutant identified is PM2.5, with a measured concentration of 46.71 µg/m³ based on eight valid observations reported through OpenAQ.

PM2.5 levels are the focus of the current assessment, and no other pollutants have been specified for this period. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Nong Samet contains measurements from eleven recorded rows collected at two monitoring sites. All nine pollutants tracked by the OpenAQ feed are present: carbon monoxide (CO), nitrogen dioxide (NO₂, shown as NO2), ozone (O₃, shown as O3), particulate matter of three size fractions (PM1, PM10 and PM2.5), sulfur dioxide (SO₂), relative humidity and temperature (the latter is listed but not reported in the current rows). The most recent values were recorded on 2026‑02‑10 at 22:00 UTC for PM2.5, NO₂, SO₂, PM1 and relative humidity, while CO and O₃ are older, last updated on 2025‑10‑10 14:00 UTC and 2025‑09‑16 07:00 UTC respectively; the single PM10 reading dates back to 2024‑05‑28 13:00 UTC. Overall, eight of the eleven rows have timestamps within the past week, while three are several months or years old, indicating a mixed freshness profile across pollutants.

Across the recent observations, PM2.5 values range narrowly from 44.3 to 46.7 µg/m³ with a median of about 45.5 µg/m³, suggesting little variation in this metric during the latest sampling period. Relative humidity is similarly stable at roughly 61.66 % for the same timestamp. In contrast, particulate matter measured as PM1 shows a single value of 30.89 µg/m³, and CO remains constant at 0.2 ppm, reflecting limited temporal depth for those parameters. The older PM10 reading stands alone at 31.0 µg/m³, and O₃ is fixed at 0.06 ppm from a 2025‑09‑16 record.

Because the data come from only two stations and several pollutants have outdated or single‑point records, the picture of air quality in Nong Samet is incomplete and may not capture short‑term fluctuations or spatial differences within the city. Users should keep in mind that conditions can vary by location and time beyond what these snapshots reveal.
