No reference monitor here, so the value is the median of low-cost sensors (at least two reporting each hour). Low-cost sensors can read high in humid air. Data via OpenAQ; licences as listed. How we rank. Embed this on your site.

Updated 2026-10-01 04:07 UTC. Values are PM2.5 in µg/m³ (fine particles), the median of each city's monitors.
