Delhi's air is a disaster. It's immediately apparent just before landing. After leaving the terminal one can literally see and smell the dirty smog, especially in winters. Air pollution's quite bad in Inland Empire, California as well (Riverside, San Bernardino, etc). One can see the air that they breathe.
