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 dataset for Medan includes five measured variables: PM1, PM2.5, relative humidity, temperature and the particle count UM003. All of these come from a single monitoring location identified as “Medan Bung,” so the station coverage is one row in the OpenAQ feed. Each pollutant’s most recent reading was recorded on 2026‑02‑10 at 16:00 UTC, meaning the data are fresh within the last three days for every parameter.

The values themselves show very little variation because only one observation is available. PM1 registers at 41.0167 µg/m³, while PM2.5 is 69.8292 µg/m³; both have identical minimum, median and maximum figures, indicating no spread in the sample. Relative humidity sits at 68.3292 % and temperature at 29.1792 °C, again with a single point of data. The UM003 particle concentration is reported as 11 033.5417 particles/cm³, also without any range.

Because the dataset consists of a solitary recent snapshot, it cannot capture spatial or temporal differences across Medan. While the timestamps are current, the lack of multiple stations or repeated measurements means that broader city‑wide conditions may differ from what is shown here. Users should keep in mind that this single‑point view provides only an instantaneous picture rather than a comprehensive overview of air quality trends throughout the city.

Data notes

The data shown for Medan reflects five valid measurements and is updated within three days, with the most recent reading recorded on 2026‑02‑10 at 16:00 UTC. This snapshot provides a current view of citywide air quality but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
