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 Viengthong – Bolikhamxai monitoring set currently provides data for five pollutants: PM1, PM2.5, relative humidity, temperature and UM003 (particle count). All of the information comes from a single reporting station, represented by five rows in the OpenAQ feed. Each pollutant has one recorded value, so the minimum, median and maximum are identical for every metric.
The most recent measurements were all taken at 2026-02-10 20:00 UTC, which places them well within the “updated within 7 days” freshness window used by the platform. Because the timestamps are uniform across pollutants, there is no lag between different variables; the data snapshot reflects conditions at a single point in time rather than an ongoing series.
Because each pollutant shows a single value, the dataset does not reveal any spread or variability. PM1 registers 13.647 µg/m³, PM2.5 records 22.084 µg/m³, relative humidity is 49.04 %, temperature sits at 24.38 °C and UM003 measures 946.428 particles/cm³. With only one station contributing, the coverage for Viengthong District is limited to this location, meaning that conditions elsewhere in the district may differ from what these figures capture. The lack of multiple rows or historic points also means trends cannot be assessed from this dataset alone.
