Refraction, specifically the real component of refraction n (describes bending of rays, wavelength changes relative to a vacuum, affects blackbody fluxes and intensities — as opposed to the imaginary component, which is related to absorption and emission) is relatively unimportant to shaping radiant fluxes through the atmosphere on Earth (except on the small scale processes where it (along with difraction, reflection) gives rise to scattering, particularly of solar radiation — in that case, the effect on the larger scale can be described by scattering properties, the emergent behavior).

Without such absorption of solar radiation high in the atmosphere there would be no stratosphere, and the temperature would decrease monotonically with height.

Moreover, the atmospheric temperature gradient is mitigated by the absorption of solar radiation within the atmosphere (also latent heat deposition), thus a more moderate temperature gradient is established within the ral atmosphere.

The cell also overcomes some of the major problems with current solar tech like wear out or damage from high heat that comes from the absorption of great amounts of ultraviolet and infrared radiation that can't actually be turned into electricity due to a narrow band gap (the wavelength of light that can effectively be used to generate electricity).

Heating of the thermosphere is due to absorption of highly energetic solar radiation by the small amount of residual molecular oxygen still present, and temperatures can rise to 2,000 deg.

Students know the fate of incoming solar radiation in terms of reflection, absorption, and photosynthesis.

«Because the solar - thermal energy balance of Earth [at the top of the atmosphere (TOA)-RSB- is maintained by radiative processes only, and because all the global net advective energy transports must equal zero, it follows that the global average surface temperature must be determined in full by the radiative fluxes arising from the patterns of temperature and absorption of radiation.»
