Beautiful phenomena in the skies : a colorful journey in the realm of atmospheric optics

There is a multitude of fascinating beautiful phenomena in nature which is related to the atmosphere. These include for example mirages, rainbows, halos, glories, or coronas, but also auroras, eclipses or the colorful skies with or without clouds from before sunrise to well after sunset. The talk will shortly discuss the underlying physics, i.e. scattering and/or emission of light from the constituents of the atmosphere, and then present a survey mostly with photographs of such marvels in nature as seen from earth and partly also from space.
