Ulaanbaatar's air quality faces among the world's most severe winter urban air quality challenges, with the enclosed Tuul River valley at 1,350 metres surrounded by the Bogd Khan and Chingeltei mountain ranges trapping intense coal and wood burning from the vast ger district's unregulated heating alongside vehicle emissions on the Peace Avenue. Winter PM2.5 routinely reaches catastrophic levels, while summer air quality is generally good with the Mongolian plateau's winds providing effective ventilation throughout the warmer months.
