Ulaanbaatar, the world's coldest capital, spends each long winter under some of the planet's worst air pollution: hundreds of thousands of ger-district households burn raw coal and wood for heat, and PM2.5 readings have peaked dozens of times above WHO guidance. That has made air-quality data the city's most consequential smart-infrastructure bet — the national agency NAMEM and the municipality's Air Pollution Reduction Department run roughly 16 fixed monitoring sites whose real-time readings appear publicly on agaar.mn. Home to about 1.6 million people, nearly half of all Mongolians, the city paired that monitoring with a 2019 ban on raw-coal sales and cleaner-fuel programmes.
