Las Vegas's air quality is shaped by the Mojave Desert basin topography that traps vehicle and resort emissions under frequent temperature inversions, with windblown desert dust from the surrounding Nevada landscape contributing elevated PM10. The intense summer heat drives ozone formation from the Strip's concentrated traffic, while the dry desert climate limits natural air washing.
