Estimates of the recovery time of stratospheric ozone heavily rely on the exact knowledge of the processes that lead to the decomposition of the relevant halogenated source gases. Crucial parameters in this context are Fractional Release Factors (FRFs) as well as stratospheric lifetimes and Ozone Depletion Potentials (ODPs). I will present observational data from the analysis of air samples collected in the mid- and high latitude stratosphere. The newly calculated values may have important implications for the severity and recovery time of stratospheric ozone loss.
