Dataset accompanying the publication: Role of Natural Halogen Chemistry on the Evolution of Global Stratospheric Ozone Depletion

Dataset accompanying the publication: Role of Natural Halogen Chemistry on the Evolution of Global Stratospheric Ozone Depletion Description-----------This archive contains the model output data used to generate the analyses and figures presented in the manuscript. All datasets are provided in NetCDF format and contain monthly zonal mean values. Directory structure------------------- The ZIP archive contains two main directories: AllHAL/ NoNatHAL/ corresponding to the two simulations described in the manuscript. Each simulation directory contains five subdirectories: mem1/ mem2/ mem3/ These directories contain the output from the three ensemble members used in the analysis. ReleaseRates/ This directory contains the vertical distributions of in-situ release of reactive halogens in extrapolar latitudes during 1990–2020 for chlorine (Cl), bromine (Br), and iodine (I). These data were used to produce Figure 2 of the main manuscript. spatial_fields/ This directory contains full spatial-resolution (latitude-longitude) model outputs for 1990–2020 from the three ensemble members, used to reproduce Figures 4A and 4C of the main manuscript. Model output variables:---------------------- The ensemble-member directories contain NetCDF files with the following diagnostics: 1. Ozone volume mixing ratio - O3 2. Halogen-mediated ozone loss reaction rates decomposed into reaction families of halogens, described in Supplementary Table S2. - OddOx_CLOx_Loss - OddOx_BrOx_Loss - OddOx_CLOxBrOx_Loss - OddOx_IOx_Loss 3. Inorganic halogen volume mixing ratios - CLOy - BROy - IOy 4. Surface downwelling solar flux - FSDS_d1: diagnostic asuming all forcings. - FSDS_d2: diagnostic asuming single-subtraction of ozone. 5. Stratospheric ozone column - O3_VCD_strat
