Air quality today
The air quality in Phitsanulok is currently classified as Moderate. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 29.0 µg/m³ and a PM10 reference value of 56.0 µg/m³, based on four valid observations.
Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
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 Phitsanulok contains measurements from a single monitoring site, giving a total of six pollutant rows. All six common air‑quality species 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).
Four of the pollutants – CO, NO₂, PM₁₀ and PM₂.₅ – have data that were last updated on 2026‑02‑10 at 22:00 UTC, which falls within the “updated within 7 days” freshness category. In contrast, O₃ is based on a measurement from 2025‑06‑30 21:00 UTC and SO₂ from 2025‑10‑10 15:00 UTC, both of which are classified as older records.
The values themselves show no variation across the recent observations: CO is consistently 1.2 ppm, NO₂ stays at 0.018 ppm, PM₁₀ remains at 56 µg/m³ and PM₂.₅ at 29 µg/m³ for the latest timestamp. Ozone registers a flat 0.0 ppm in its older entry, while SO₂ is recorded at 0.006 ppm. Because each pollutant has only one reported figure, there is no spread or range to describe – the median, minimum and maximum are identical for every species.
Overall, the coverage is limited to a single location, and while half of the pollutants have very recent data, the other half rely on measurements that are several months old. Consequently, the snapshot reflects conditions at one point in time and place, and broader city‑wide variations may not be captured by this dataset.
