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 Met District air‑quality feed currently includes five measured variables: PM1 at 19.75 µg/m³, PM2.5 at 28.17 µg/m³, relative humidity at 54.30 %, temperature at 23.68 °C and UM003 particle count at 1 142.25 particles/cm³. All of these values come from a single monitoring row located in the Mad – Vientiane station, so the dataset reflects just one measurement point within the city.
The most recent update for every pollutant was recorded on 2026‑02‑10 at 20:00 UTC, meaning the data are fresh within the last seven days. Because there is only one row (rt = 5 rows total, but only one station reporting), the range for each parameter is identical to its median and maximum – there is no observed spread across multiple sites or times. Consequently, while the figures give a snapshot of conditions at that moment, they do not capture spatial variability across Met District.
Because coverage is limited to a single location, any changes in local micro‑environments—such as traffic hotspots or nearby construction—will not be reflected in these numbers. Users should keep in mind that the reported values represent one point in time and space; broader city‑wide conditions may differ from this snapshot.
