title: Chapter 8 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 8.13 (v20220718)

description: Data for Figure 8.13 from Chapter 8 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Figure 8.13 shows zonal and annual mean projected long-term changes in the atmospheric water budget. --------------------------------------------------- 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: Douville, H., K.

Each sub-panel NetCDF file has 6 variables. The variable names have suffix: - mean for multi-model change mean (thick coloured line) - land_mean for multi-model change mean over land (thick black line), - pctl5 and pctl95 for multi-model 5 and 95 percentiles (coloured shaded area), - variab5 and variab95 for 5 and 95 percentiles of the internal variability (grey shaded area). As an example Fig8-13_pr_ssp126.nc (precipitation, scenario SSP1-2.6), relates to the upper panel (left). CMIP6 is the sixth phase of the Coupled Model Intercomparison Project. SSP126 is the Shared Socioeconomic Pathway which represents the lower boundary of radiative forcing and development scenarios, consistent with RCP2.6. SSP245 is the Shared Socioeconomic Pathway which represents the median of radiative forcing and development scenarios, consistent with RCP4.5. SSP585 is the Shared Socioeconomic Pathway which represents the upper boundary of radiative forcing and development scenarios, consistent with RCP8.5. --------------------------------------------------- Sources of additional information --------------------------------------------------- The following weblinks are provided in the Related Documents section of this catalogue record: - Link to the figure on the IPCC AR6 website - Link to the report component containing the figure (Chapter 8) - Link to the Supplementary Material for Chapter 8, which contains details on the input data used in Table 8.SM.1 - Link to the code for all figures in Chapter 8, archived on Zenodo. - Link to the documentation for CAMMAC, the tool used for AR6 analysis.
