Abstract
Atmospheric photochemical processes often occurring at altitudes of tens of kilometres above the surface can be of paramount importance to the existence of life on Earth. Formed by complex chemical and photodissociation processes, the ozone layer absorbs harmful ultraviolet radiation in the stratosphere before it reaches the Earth surface. The deoxyribose nucleic acid molecules (DNAs) of most organisms absorb very strongly at wavelengths around 300 nm. Had this radiation not been prevented from reaching the ground, it would have caused immediate and significant tissue damage and led to formation of cancer cells and genetic mutations.
