WebThis is known as Wien’s displacement law. Since the solar emission tempera-ture is about 6000K and the maximum of the solar spectrum is (see Fig.2.2) at about 0.6µm – i.e., in the visible – and we have determined Te=255K for the Earth, it follows that the peak of the terrestrial spectrum is at λearth m =0.6µm× 6000 255 ' 14µm. WebThe radiation of a blackbody radiator is produced by the thermal activity of the material, not the nature of the material, nor how it got thermally excited. Some examples of blackbodies include incandescent light bulbs, stars, and hot stove tops. The emission appears as a continuous spectrum (Figure 1.1.3 ) with multiple coexisting colors. WebThe figure below [1] indicates that Planck's law matches the solar spectrum pretty well, apart from emission lines (like the H line) and absorption lines (for example Ca II).

"WebIntroduction to Solar Radiation. Radiation from the sun sustains life on earth and determines climate. The energy flow within the sun results in a surface temperature of around 5800 K, so the spectrum of the radiation from the sun is similar to that of a 5800 K blackbody with fine structure due to absorption in the cool peripheral solar gas (Fraunhofer lines).

WebThe solar spectrum at the top of the Earth's atmosphere is approximately a blackbody spectrum with a temperature of 5780 K. We can use Planck's law to calculate the spectral radiance of the sun at different wavelengths and integrate over the relevant wavelength range to obtain the total solar radiation in that range. WebIt is characterized as the best post-1992 solar spectrum estimate. The iradiance outside the atmosphere can be compared with the blackbody curve at 6000K, a portion of which is reproduced at right. By examining the 400-700 nm nominal range of visible light, you can see that the solar irradiance is similar to that of a blackbody radiator.
