Divine Experience DSC04509 sunrise
Sunrise or sun up is the instant at which the upper edge of the Sun appears on the horizon in the morning. The term can also refer to the entire process of the sun crossing the horizon and its accompanying atmospheric effects.
Colors 10 minutes before sunrise. Air molecules and airborne particles scatter white sunlight as it passes through the Earth's atmosphere. This is done by a combination of Rayleigh scattering and Mie scattering.
Sunrise vs. Sunset colors
Sunset colors are sometimes more brilliant than sunrise colors because evening air typically contains more large particles, such as clouds and smog, than morning air. These particles glow orange and red due to Mie scattering during sunsets and sunrises because they are illuminated with the longer wavelengths that remain after Rayleigh scattering.
If the concentration of large particles is too high (such as during heavy smog), the color intensity and contrast is diminished and the lighting becomes more homogenous. When very few particles are present, the reddish light is more concentrated around the Sun and is not spread across and away from the horizon
