Solar Radiation
</dt>
The total electromagnetic
radiation emitted by the sun. See insolation,
direct
solar radiation, diffuse
sky radiation, global
radiation, extraterrestrial
radiation, solar
constant.

To a first approximation, the sun radiates as a black body at a
temperature of about 5700 degrees K; hence about 99.9 percent of its energy
output falls within the wavelength interval from 0.15 micron to 4.0 microns,
with peak intensity near 0.47 micron. About one-half of the total energy in
the solar beam is contained within the visible spectrum from 0.4 to 0.7
micron, and most of the other half lies in the near infrared, a small
additional portion lying in the ultraviolet.
