Supplementary data for: Observationally-derived Fractional Release Factors, Ozone Depletion Potentials, and Stratospheric Lifetimes of Four Long-Lived CFCs: CFC-13 (CClF3), CFC-114 (C2Cl2F4), CFC-114a (CF3CCl2F), and CFC-115 (C2ClF5)

This dataset accompanies the paper 'Observationally-derived Fractional Release Factors, Ozone Depletion Potentials, and Stratospheric Lifetimes of Four Long-Lived CFCs: CFC-13 (CClF3), CFC-114 (C2Cl2F4), CFC-114a (CF3CCl2F), and CFC-115 (C2ClF5)' (Tuffnell, E., Leedham-Elvidge, E., Sturges, W., Bönisch, H., Adcock, K., Fraser, P., Krummel, P., Oram, D., Langenfelds, R., Röckmann, T., Western, L., Mühle, J., and Laube, J.: Observationally-derived Fractional Release Factors, Ozone Depletion Potentials, and Stratospheric Lifetimes of Four Long-Lived CFCs: CFC-13 (CClF3), CFC-114 (C2Cl2F4), CFC-114a (CF3CCl2F), and CFC-115 (C2ClF5), EGUsphere [preprint], https://doi.org/10.5194/egusphere-2025-4941, 2025.) The first file file contain trace gas mixing ratios (MR, ppt) and uncertainties, Fractional Release Factors (FRFs) and mean ages of air (mAOA) for each compound of interest in the manuscript (CFC-13, CFC-114, CFC-114a, and CFC-115) from 5 flights of the high-altitude research aircraft M55 Geophysica. The second file contains the background trend taken from Cape Grim, Tasmania and measured at UEA, The third, fourth, fifth and sixth files contain the emissions data for these compounds, updated from Western et al., (2023) (doi:10.1038/s41561-023-01147-w). For further details please refer to the corresponding manuscript (ideally the final version, once published).
