SF6 and CFC-12 measurements and mean age along HALO flight tracks during PGS, WISE and SouthTRAC

This dataset belongs to the paper " Mean age from observations in the lowermost stratosphere: an improved method and interhemispheric differences", submitted to ACP in 2022.

It contains

SF6 and CFC-12 measurements from the GhOST instrument (ECD-Channel),

mean age calculated using the conventional TR-only method (mA_fit),

mean age calculated using the extended exTR-TR method (mA_fit_fracts)

and flight track information (delta theta, equivalent latitude, latitude, longitude

in csv format for the three aircraft campaigns PGS (PGS_age.csv), WISE (WISE_age.csv) and SouthTRAC (ST_age.csv).

Mean age values have not been corrected for mesospheric loss of SF6.

The Python code tools for reproducing mean age calculations are available at
