Air quality today

The air quality in Phonsavan today is classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 16.39 µg/m³ based on five valid observations reported through OpenAQ.

Data for this assessment come from a limited set of recent measurements and reflect the current conditions without additional context. 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 Phonsavan monitoring set currently provides data for five measured variables: PM1, PM2.5, relative humidity, temperature and the particle count UM003. All of these come from a single reporting row – one sensor location identified as Pek – Xiengkhouang – so the station coverage in the city is limited to just one measurement point.

The most recent readings were all recorded at the same moment on 2026‑02‑10 20:00 UTC, meaning the dataset is fresh but only reflects conditions from that single timestamp. For each pollutant the reported value is also the sole statistic available: the minimum, median and maximum are identical. PM1 registers at 8.35 µg/m³, PM2.5 at 16.39 µg/m³, relative humidity sits at 52.68 %, temperature is 20.49 °C, and UM003 shows a concentration of 627.90 particles per cm³.

Because there is only one row, the range for every parameter collapses to a single point, so no spread or variability can be derived from this source alone. The uniform freshness across all five variables indicates that when data are present they are updated together, but the lack of multiple stations means city‑wide conditions may differ elsewhere and at other times. Users should keep in mind that these figures represent a snapshot from one location rather than a comprehensive view of air quality throughout Phonsavan.
