Abstract
Practically all natural daytime light at the Earth’s surface originates in the Sun. The fluence rate, as well as spectral and directional distributions are modified by the gases, clouds and aerosols in the atmosphere in a way which depends on time and place, and also by vegetation, snow, and other ground-cover. A special section in this chapter is devoted to ultraviolet radiation.
