   Does 'pollution' cause red sunsets?

   • "In an atmosphere with no junk at anytime, you'll never get a sunset that would make someone with normal color vision say, 'Wow that's red!'" says Craig Bohren, professor emeritus of meteorology at Pennsylvania State University. "It is certainly true that the 'pollution' results in redder sunsets."

   Are red sunrises a result of air pollution?

   • Yellow and orange light has shorter wavelengths than red light, so sunsets and sunrises in polluted areas often have a higher proportion of red light. That isn’t to say that every red sunrise or sunset is the result of air pollution.

   Can air pollution cause red skies?

   • Even without air pollution, we would still experience red skies — at least to an extent. But as you’ve seen, excess pollution in the air can make sunrises and sunsets have a brighter red glow. It can even make the sky appear red at night or during the day.

   How does pollution affect sunsets?

   • When the sun sets, sunlight traveling through the atmosphere comes in contact with pollutants, causing them to scatter and create beautiful sunsets. This is a case where dirty practices affect the sunsets.

   Do aerosols make a sunset red?

   • So, although aerosols may make a sunset red, excess pollution will also dampen the overall sunset experience. In fact, the transition from day to night might be a whole lot peachier—and healthier—without all that atmospheric flotsam.

   How does air pollution affect red light?

   • Smoke and other larger particles are particularly good at scattering red light. Unfortunately, air pollution from human-made aerosols also scatters red light very effectively. When the air is densely polluted, more of the shorter wavelengths of light scatter completely away before we see them.

   What results is an incredibly red sunset until the ash clears. But smog from a smoke stack or ­car is composed of particles of so many different sizes, the scattering is nearly indiscriminant. Rayleigh scattering is no longer in effect, since instead of the atmosphere scattering only certain wavelength as sunlight passes through it, it ...
