Solar Radiation

http://topex.ucsd.edu/rs/radiation.pdf

Figure shows blackbody radiation curves for the Sun at 6000˚K and the Earth at 288˚K. The solar radiation peaks in the visible part of the spectrum while the Earth has a peak in the thermal infrared part of the spectrum (~ 10 µm).

Radiation from the Sun and Earth

Figure shows the theoretical blackbody radiation curve for 5250˚C (black curve). Solar radiation at the top of the atmosphere is well approximated by a blackbody spectrum (yellow). The atmosphere absorbs and reflects radiation so the spectral radiance at sea level is lower and has bands of low incident radiation. Note that the peak in the spectral radiance from the sun occurs in the visible part of the spectrum.
