Mean age of the air in years from tropopause is calculated using tropospheric trends 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. Moore, F. L., J. W. Elkins, E.
