title: Chapter 6 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 6.SM.5 (v20220930)

description: Data for Figure 6.SM.5 from Chapter 6 Supplementary Material of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Figure 6.SM.5 shows future global and regional changes in annual mean surface O3, relative to the 2005-2014 mean, for the different SSPs used in CMIP6. --------------------------------------------------- How to cite this dataset --------------------------------------------------- When citing this dataset, please include both the data citation below (under 'Citable as') and the following citation for the report component from which the figure originates: Szopa, S., V.

Available from https://www.ipcc.ch/ --------------------------------------------------- Figure subpanels --------------------------------------------------- The figure has 11 panels with data provided for all panels in 4 files placed in the directory. --------------------------------------------------- List of data provided --------------------------------------------------- This dataset contains precomputed values of surface ozone concentrations across world regions for: - A 10-year mean period (2005 to 2014) from the historical simulation to represent present day regional mean values. Regional multi-model annual mean and standard deviation values are calculated across 5 different CMIP6 models - Annual multi-model mean values of surface ozone from 5 different CMIP6 models projected for 7 different future scenarios covering the period 2015 to 2100 - Standard deviation values of surface ozone from 5 different CMIP6 models projected for 7 different future scenarios covering the time period from 2015 to 2100 - Annual 10-year mean values of surface ozone from the TM5-FASST model projected for 5 different future scenarios covering the period 2015 to 2100 --------------------------------------------------- Data provided in relation to figure --------------------------------------------------- All the data files provided are used to create the time series plots for each region. The numbers in each panel for each region are obtained from 'Surf_O3_data_05_14_mean_for_IPCC_figure_V1_5mods.csv', with the time series line for each scenario from 'Surf_O3_data_fut_mean_for_IPCC_figure_V1_5mods.csv' and the shading obtained by using the values in 'Surf_O3 _SD_data_fut_mean_for_IPCC_figure_V1_5mods.csv'. The TM5-FASST data is included on the figure by reading in pre-computed regional mean values from the 'Regional_annual_mean_surface_O3_resp_values_CMIP6_Fut_Scens_from_TM5_FASST_on_AR6_reg_receptors_INCL_GLOB_2015_2100.txt' file. --------------------------------------------------- Notes on reproducing the figure from the provided data --------------------------------------------------- The plotting code that is provided along with this dataset should just be able to read in each of the precomputed regional mean .csv files and then reproduce the time series figures. --------------------------------------------------- Sources of additional information --------------------------------------------------- The following weblinks are provided in the Related Documents section of this catalogue record: - Link to the report component related to the figure (Chapter 6) - Link to the Supplementary Material for Chapter 6, which contains details on the input data used in Table 6.SM.3 - Link to the code for the figure, archived on Zenodo.
