Air quality today
The air quality today in Chaophraya Surasak is classified as USG. The primary pollutant identified is PM2.5, with a measured concentration of 46.0 µg/m³ based on one valid observation reported through OpenAQ.
Data for this location are limited to the single measurement available, and no additional pollutants have been reported at this time. 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
Chaophraya Surasak’s air‑quality record is built from a single monitoring site operated by the Health Promotion Hospital Bankhaohin, so every pollutant reading comes from one location. The dataset therefore contains four rows – one for each of the measured species NO₂, O₃, PM10 and PM2.5 – and no additional stations contribute data.
The most recent values are mixed in terms of freshness. The nitrogen dioxide (NO₂) and ozone (O₃) observations were last updated on 2025‑05‑20 at 01:00 UTC, which places them just beyond a year old. Particulate matter with a diameter below 10 µm (PM10) is older still, with its latest entry dated 2023‑03‑31 at 17:00 UTC, nearly three years ago. By contrast, the fine particulate matter measurement (PM2.5) is current, having been refreshed on 2026‑02‑14 at 22:00 UTC – within the last day.
All four pollutants show a single reported value rather than a range of measurements. NO₂ registers a constant 0.0 ppm, O₃ records 0.036 ppm, PM10 is fixed at 34.0 µg/m³ and PM2.5 sits at 46.0 µg/m³; each metric’s minimum, median and maximum are identical, indicating no observed variation over the recorded periods. Because only one station supplies data, there is no spatial spread to capture differences across neighborhoods or micro‑environments within Chaophraya Surasak.
Overall, the dataset offers a limited snapshot: three of the four pollutants rely on information that is more than a year old, while only PM2.5 provides a recent reading. Users should keep in mind that air quality can change throughout the day and across different parts of the city, so these single‑point, dated values may not reflect current conditions everywhere in Chaophraya Surasak.

Data notes
The data shown for Chaophraya Surasak is based on a single valid measurement and was Updated within 3 days, with the most recent reading recorded at 2026‑02‑10T22:00:00+00:00.
