Data from satellite, balloon, and ground-station measurements show that ozone loss is strongly correlated with cosmic-ray ionization-rate variations with altitude, latitude, and time. Moreover, our laboratory data indicate that the dissociation induced by cosmic rays for CF2Cl2 and CFCl3 on ice surfaces in the polar stratosphere at an altitude of ~15 km is quite efficient, with estimated rates of 4.3×10-5 and 3.6×10-4 s-1, respectively. These findings suggest that dissociation of chlorofluorocarbons by capture of electrons produced by cosmic rays and localized in polar stratospheric cloud ice may play a significant role in causing the ozone hole.
