Beside above, why does polluted air appear reddish brown? Nitrogen oxides are at least partially responsible for several types of air pollution. Nitrogen dioxide lends its color to the reddishbrown haze we call smog. Photodissociation of nitrogen dioxide by sunlight produces nitric oxide and ozone in the troposphere, which is another component of smog.

Subsequently, one may also ask, how does haze affect the environment?

Haze is one of the most basic forms of air pollution and degrades visibility in many American cities and scenic areas.
