Air quality today

The air quality today in Si Sa Ket Town Municipality is classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 18.5 µg/m³.

Data for this assessment come from OpenAQ and are based on five valid measurements taken during the reporting period. No additional pollutants have been reported for today. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Si Sa Ket Town Municipality data set contains measurements for ten variables: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of 1 µm, 2.5 µm and 10 µm (PM₁, PM₂.₅, PM₁₀), relative humidity, sulfur dioxide (SO₂), temperature and the UM003 parameter. These observations come from four monitoring stations that together provide 27 individual rows of data.

The most recent readings are from early February 2026 for several key pollutants. The latest PM₂.₅ value recorded at the Sisaket Meteorological Center was 18.5 µg/m³ on 2026‑02‑10 22:00 UTC, while NO₂ and O₃ were both measured that same day at 0.002 ppm and 0.017 ppm respectively. SO₂ also shows a recent zero reading from the same timestamp. In contrast, PM₁₀, PM₁, relative humidity and temperature are only available from older entries dated 2025‑01‑13 23:00 UTC, with the highest recorded PM₁₀ of 61.45 µg/m³ at โรงเรียนเทศบาล3.

Across the pollutants, median values give a sense of typical conditions: PM₂.₅ sits at 18 µg/m³, PM₁₀ at 25 µg/m³, NO₂ at 0.007 ppm and O₃ at 0.018 ppm. The spread is notable – the minimum PM₂.₅ observed was about 3.7 µg/m³ while the maximum reached roughly 48 µg/m³, and for PM₁₀ the range runs from 4 µg/m³ up to 61 µg/m³. Relative humidity varies between 54.7 % and 75.6 %, and temperature ranges from 17.8 °C to 24.4 °C.

Overall, half of the variables rely on data that is more than a year old, so the picture of air quality in Si Sa Ket may not capture recent short‑term fluctuations. The newer timestamps for gases and fine particles provide a fresher snapshot, but the older particulate and meteorological records highlight uneven coverage across the dataset.
