Photoionization and photo-dissociative ionization cross sections of major solar atmosphere atoms and molecules. Photoionization and photo-dissociative ionization cross sections for each wavelength. (Left) Photoionization cross section of oxygen atom, (middle) cross section of photoionization and photo-dissociative ionization of oxygen molecule, and (right) photoionization and photodissociation of nitrogen molecule. Cross-section data are based on Solomon and Qian (2005)
