Tropospheric Ozone and Smoke from Earth Probe TOMS: Indian Ocean
Researchers have discovered that smoke and smog move in different ways through the atmosphere. A series of unusual events several years ago created a blanket of pollution over the Indian Ocean.

In this animation, significant smog or tropospheric ozone is represented by red and green and regions of significant smoke index are in shades of white and gray.
