Possible Anthropogenic Influences on Stratospheric Ozone
The intensity of radiation emitted from the sun has its maximum at wavelengths near 500 nm, consistent with its 6000K surface temperature, and is presumed to have done so without large variations for hundreds of millions of years. The natural solar satellites, including the Earth, must therefore have evolved in ways which are responsive to this constant photochemical bombardment. Our usual designations for the various portions of the solar spectrum are oriented toward homo sapiens and the possession by that biological species of an efficient photon detection system which is both extremely sensitive toward solar radiation and capable of discrimination among the various wavelengths of light 760 nm (“red”) to 400 nm (“violet”). Not surprisingly, the wavelengths of radiation detected by the eye of man include the broad band covering the most intense solar emission. Our description system further classifies solar radiation not detected by the human eye into those wavelengths which are longer than those in the visible region, i.e. infrared, with λ>760 nm, and those wavelengths shorter, i.e. ultraviolet with λ<400 nm.
