What is Haze?

When sunlight encounters tiny particles in the air, the particles both absorb
and scatter the oncoming light.  This absorption and scattering of light
degrades the color, clarity and contrast of the view, and causes the distance
that we can see to be limited.  Descriptively, we call this phenomenon "haze."
