ure on the right is calculated using the solar geometry routine in Ref. as follows: 1.) For a given latitude and a given date, calculate the declination of the Sun using {\displaystyle 0^{\circ }}{\displaystyle 0^{\circ }} longitude and solar noon time as inputs to the routine; 2.) Calculate the sunrise hour angle using the sunrise equation; 3.) Calculate the sunrise time, which is the solar noon time minus the sunrise hour angle in degree divided by 15; 4.) Use the sunrise time as input to the solar geometry routine to get the solar azimuth angle at sunrise. Hemispheric symmetry An interesting feature in the figure on the right is apparent hemispheric symmetry in regions where daily sunrise and sunset actually occur. This symmetry becomes clear if the hemispheric relation in sunrise equation is applied to the x- and y-components of the solar vector presented in Ref.

h Macedonia, showing vivid red, orange and pink. Sunrise over Placida Harbor, Florida Colors See also: Atmospheric optics 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. As a ray of white sunlight travels through the atmosphere to an observer, some of the colors are scattered out of the beam by air molecules and airborne particles, changing the final color of the beam the viewer sees. Because the shorter wavelength components, such as blue and green, scatter more strongly, these colors are preferentially remov
