Chapter 11 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 11.19 (v20230203)

Data for Figure 11.19 from Chapter 11 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Figure 11.19 shows projected changes in the number of consecutive dry days (CDD), annual mean soil moisture over the total column, and the frequency and intensity of one-in-ten year soil moisture (SM) drought for the June-to-August and December-to-February seasons at 1.5°C, 2°C, and 4°C of global warming compared to the 1851-1900 baseline. --------------------------------------------------- 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: Seneviratne, S.I., X.

Note that grid cells with no change (0) have been replaced by 10^-5 such that the logarithm is defined. --------------------------------------------------- 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 11) - Link to the Supplementary Material for Chapter 11, which contains details on the input data used in Table 11.SM.9 - Link to the Ch11 GitHub repository containing scripts for generating figures - Link to the code for the figure, archived on Zenodo.
