Total chlorine and bromine are based on in situ measurements of organic
species from either the Airborne Chromatograph for Atmospheric Trace
Species (ACATS-IV) [see Elkins et al., 1996] or the Lightweight Airborne
Chromatograph Experiment (LACE).  Mean age of the air in years from the
tropical tropopause is calculated using tropospheric trends from Geller et
al., [1997] and a formula from Volk et al., [1997].  Total chlorine
calculations are based on total chlorine from Montzka et al., [1996] and
model generated correlations from Woodbridge et al. [1995] are used for the
missing chlorine species, HCFC-22 and CH3Cl.  Total bromine calculations
are from Wamsley et al., [1997] where missing bromine organic species
(CH3Br, halon-2402, halon-1301, CH2Cl2, and CH2BrCl) are calculated from
correlations of NCAR WAS data versus CFC-11 are used.  All values derived
from theta < 380 were excluded, because of influence from the troposphere.
All calculations of total halogen and inorganic halogen assume no inorganic
input from the troposphere (Cly, Bry=0).

ACATS did not measure N2O.  To calculate CH3CCl3 ATLAS N2O was used.
ACATS did not measure SF6 on this flight.  Mean age of air cannot be calculated.
ACATS did not measure CH3CCl3.  A derived CH3CCl3 from CFC-11 correlation is used in place.
