Air quality today

The air quality in Pho Sa is classified as USG today. The primary pollutant identified is PM2.5 (fine particles). Measurements from six valid observations show a PM2.5 reference value of 41.1 and a PM10 reference value of 77.0.

Data are shown via OpenAQ, reflecting the current monitoring results for the city. 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 Pho Sa is based on a single monitoring site, the Chaloem Phra Kiat Water Park, which contributed six data rows—one for each of the measured pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All six measurements were last updated on 2026‑02‑10 at 22:00 UTC, so the dataset is current within the past week.

Because each pollutant has only one reported value, the statistical spread is effectively zero. CO registers a constant 0.5 ppm, NO₂ stays at 0.023 ppm, O₃ at 0.011 ppm, PM₁₀ at 77.0 µg/m³, PM₂.₅ at 41.1 µg/m³ and SO₂ at 0.001 ppm; the minimum, median, 10th percentile, 90th percentile and maximum are identical for every parameter. This uniformity means there is no observed variability in the recent snapshot, limiting insight into how conditions might fluctuate across the city or over time.

The dataset’s narrow coverage—one station supplying a single reading per pollutant—means that local air‑quality conditions could differ elsewhere in Pho Sa and at other times of day. While the information is fresh, its lack of depth and spatial diversity should be kept in mind when interpreting the current snapshot for the city.

Data notes

The current dataset for Pho Sa includes six valid measurements and is marked as Updated within 3 days, with the latest values recorded at 2026‑02‑10T22:00:00+00:00. These figures represent a snapshot of conditions across the monitoring network; air quality can differ by specific location and time of day within the city, so individual experiences may vary from the reported averages.
