Weather Tidbits: Red Sunsets

This Weather Tidbits answers why sunsets are red? First thing to consider is the angle of the sun in that more sunlight has travel through the atmosphere at sunset compared to noon. The 2nd factor is the colors in that blue and purple which are short wavelengths get scattered easily by air & dust particles; while red & orange are left mostly unscattered while traveling the long atmosphere. Also redder sunsets are produced when plenty of dust particles are contained in the sky; such as volcanic eruptions, intense pollution or Saharan dust.
