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 air‑quality record for Thung Sadao comes from a single monitoring site operated by the Municipality Office Tungsadao, which supplies five separate pollutant rows – one each for nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10), fine particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO2). Because the dataset contains only this one station, spatial coverage across the city is limited; conditions can differ in neighborhoods that are not directly represented by the measurements.
The timestamps show a mixed picture of data freshness. The most recent entry is for PM2.5, recorded on 2026-02-10 22:00 UTC and flagged as updated within the last seven days. Ozone data were last refreshed on 2024-10-15 06:00 UTC, while PM10 was reported on 2025-05-22 22:00 UTC. In contrast, NO2 and SO2 both date back to 2023-01-20 04:00 UTC, indicating that those two pollutants have not been updated for more than three years. Overall, only one of the five pollutant rows can be described as current; the remaining four are older than a year.
The numeric values themselves are uniform within each pollutant’s record. NO2 and SO2 both read 0.0 ppm, with no variation across minimum, median or maximum. Ozone is consistently measured at 0.012 ppm, while PM10 shows a single value of 152 µg/m³ and PM2.5 a single value of 40 µg/m³. Because each pollutant has only one reported figure, there is no observable spread or trend in the data. This lack of variability, combined with the limited number of monitoring locations and the age of most records, means that the dataset provides only a snapshot rather than a comprehensive view of air quality across Thung Sadao.
