Description:
Data for Figure 6.SM.4 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.4 shows future global and regional changes in annual mean surface PM2.5, relative to the 2005-2014 mean, for the different SSPs used in CMIP6. Each line represents a multi-model mean across the region with shading representing the ±1 standard deviation in the mean.

Figure subpanels
---------------------------------------------------
The figure has 11 panels, with data provided for all panels in 4 files placed in the main directory.
---------------------------------------------------
List of data provided
---------------------------------------------------
This dataset contains precomputed values of surface PM2.5 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 5-year multi-model mean values of surface PM2.5 from 5 different CMIP6 models projected for 7 different future scenarios covering the period 2015 to 2100
- Standard deviation values of surface PM2.5 from 5 different CMIP6 models projected for 7 different future scenarios covering 5-year mean periods from 2015 to 2100
- Annual 10-year mean values of surface PM2.5 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_PM2pt5_data_05_14_mean_for_IPCC_figure_V1_5mods.csv', with the time series line for each scenario from 'Surf_PM2pt5_data_fut_mean_for_IPCC_figure_V1_5mods.csv' and the shading obtained by using the values in 'Surf_PM2pt5_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_PM2pt5_resp_values_CMIP6_Fut_Scens_from_TM5_FASST_on_AR6_reg_receptors_INCL_GLOB_2015_2100.txt' file.
CMIP6 is the sixth phase of the Coupled Model Intercomparison Project.
PM2.5 refers to fine particulate matter air pollution with diameter of less than 2.5 microns.
SSP stands for Shared Socioeconomic Pathway.

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.
