solar radiation

The total electromagnetic radiation emitted by the sun.

To a first approximation, the sun radiates as a blackbody at a temperature of about 5700 K; hence, about 99.9% of its energy output falls within the wavelength interval from 0.15 to 4.0 μm, with peak intensity near 0.5 μm. About one-half of the total energy in the solar beam is contained within the visible spectrum from 0.4 to 0.7 μm, and most of the other half lies in the near-infrared, a small additional portion lying in the ultraviolet.

1. The study of the physics, chemistry, and dynamics of the earth's atmosphere, including the related effects at the air–earth boundary over both land and the oceans. Fundamental topics include the composition, structure, and motion of the atmosphere. The goals ascribed to meteorology are the complete understanding and accurate prediction of atmospheric phenomena.
