The electromagnetic spectral distribution emitted by the sun or received by a collector or instrument on Earth. For example, Figure 2 from Shining On below shows the solar spectrum as measured in space and on the Earth's surface.
distribution by wavelength (or frequency) of solar radiation Sonnen- strahlungs- spektrum
The total distribution of electromagnetic radiant energy over the band of wavelengths present in solar radiation. The total energy received on a given surface, and how that energy is distributed among various wavelengths, depends on how much of the Earth's atmosphere light has traversed.
The total distribution of electromagnetic radiation emanating from the sun.
Radiation originating from the sun, including ultraviolet, visible, and near-infrared radiation. Approximately 99% of solar energy lies between wavelengths of 0.3 to 3.5 micrometers.
The intensity variation of sunlight across its spectral range.
The solar spectrum, commonly referred to as sunlight, consists of ultraviolet light, (UV), visible light and infrared (IR). The energy distribution within the solar spectrum is approximately 2 percent UV, 47 percent visible light and 51 percent IR. One aspect of the solar spectrum is its wavelength in which nanometer (nm) is the unit of length [1 nm+10^-9 m].
That part of the electromagnetic spectrum occupied by the wavelengths of solar radiation. The shape is well represented by the continuum emission from a blackbody with temperature near 5700 K superimposed with Fraunhofer absorption lines.
