Answer 1
March, 2021The difference in morning and evening lighting (under the same weather conditions) is caused by the fact that in the daytime, streams of air heated from the ground capture and lift up a large amount of the smallest dust. At night, this dust settles back.
When passing through this dust, the sun's rays are colored slightly redder. Visually, this is perceived as a "warmer" shade of color.
Answer 2
March, 2021Is there a sunrise or sunset in the picture? The blue part of the spectrum, which is more scattered than the red, should be scattered in the atmosphere in the same way during sunset and sunrise, if we do not take into account the evaporation of water, which leads to additional scattering. During the day, tones may become warmer due to the increasing proportion of water vapor in the air.
