Chapter 6 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 6.20 (v20220928)
Abstract
Data for Figure 6.20 from Chapter 6 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6).
Figure 6.20 shows projected changes in regional annual mean surface ozone (O3; ppb) from 2015 to 2100 in different shared socio-economic pathways (SSPs)

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 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'.
CMIP6 is the sixth phase of the Coupled Model Intercomparison Project.
SSP stands for Shared Socioeconomic Pathway.
ppb stands for parts per billion.

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. A link to the code archived on Zenodo is provided in the Related Documents section of this catalogue record.

| Abstract | Projected changes in regional annual mean surface ozone (O3; ppb) from 2015 to 2100 in different shared socio-economic pathways (SSPs). Each panel represents values averaged over the corresponding land area (except for ‘Global’) shown on the map in Figure 6.7. Solid coloured lines and shading indicate the multi-model mean and ±1 σ across the available CMIP6 models (Turnock et al. 2020; Allen et al. 2021) for each scenario. Changes are relative to annual mean values calculated over the period 2005–2014 from the historical experiment as indicated in the top left of each regional panel along with ±1 σ. For each model all available ensemble members are averaged before being used to calculate the multi-model mean. Ozone changes are also displayed in the Interactive Atlas. Further details on data sources and processing are available in the chapter data table (Table 6.SM.3). |
