Las Vegas' Bellagio Fountains air quality reflects the Strip's extraordinarily intense commercial corridor, with vehicle traffic on Las Vegas Boulevard and the surrounding extraordinary concentration of resort and casino operations generating sustained NOₓ. The Mojave Desert basin's persistent inversions affect all valley communities, while the fountains' water spray provides limited localised humidity and the Strip's commercial intensity maintains consistently elevated Las Vegas Boulevard readings throughout most of the year.
