Formulation of the cosmic ray-driven electron-induced reaction mechanism for quantitative understanding of global ozone depletion.

ABSTRACT: This paper formulates the cosmic ray-driven electron-induced reaction as a universal mechanism to provide a quantitative understanding of global ozone depletion. Based on a proposed electrostatic bonding mechanism for charge-induced adsorption of molecules on surfaces and on the measured dissociative electron transfer (DET) cross sections of ozone-depleting substances (ODSs) adsorbed on ice, an analytical equation is derived to give atmospheric chlorine atom concentration: [Formula: see text] where Φ_e is the prehydrated electron (e_pre^-) flux produced by cosmic ray ionization on atmospheric particle surfaces, [Formula: see text] is the surface coverage of an ODS, and kⁱ is the ODS's effective DET coefficient that is the product of the DET c
