Palette Of Pollution by Reuters

Each winter, a thick blanket of smog settles over vast swathes of northern India, including the capital, New Delhi. As wind speeds drop and nights get cooler, the problem is exacerbated as polluted air is pushed closer to the ground.

Here we visualise hourly readings across Delhi, showing the impact of temperature and wind speed. The colours depicted match the range of air pollution in the scale above.
