Mean age of the air in years from tropopause is calculated using tropospheric trends from Geller et al., [1997] and formula from Volk et al., [1997]. Total chlorine calculations based on total chlorine from Montzka et al.,[1996] and formula from Woodbridge et al. [1995] for missing chlorine species, HCFC-22 and CH3Cl. Total bromine calculations are from Wamsley et al., [1997]. All values derived from theta < 380 were excluded. Elkins, J. W., D. W. Fahey, J. M. Gilligan, G. S. Dutton, T. J. Baring, C. M. Volk, R.
