A Terrestrial Atmospheric Lens is a theoretical method of using the Earth as a large lens with a physical effect called atmospheric refraction. [ 1 ] The sun's image appears about a half degree above its real position during sunset due to Earth's atmospheric refraction.
Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height.
