title: Chapter 8 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 8.25 (v20220718)

description: Data for Figure 8.25 from Chapter 8 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Figure 8.25 shows the effect of first versus second 2°C of global warming relative to 1850-1900 on seasonal mean precipitation. --------------------------------------------------- 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.

Data is provided in panel-specific sub-directories. --------------------------------------------------- List of data provided --------------------------------------------------- This dataset contains CMIP6 multi-model ensemble mean December–January–February (left panels) and June–July–August (right panels) precipitation difference for: - SSP5-8.5 scenario at +2°C - SSP5-8.5 scenario at +4°C minus SSP5-8.5 at +2°C (second 2°C warming) - Second minus first 2°C fast warming. --------------------------------------------------- Data provided in relation to figure --------------------------------------------------- There are two NetCDF files per panel : - one for the main field, which is represented with colors and has 'rchange' or 'rmeans' in the filename - the other for the confidence information, based on fraction of models which agree about signal change sign, which is represented in figures by diagonal lines as specified by the so called AR6 simple hatching scheme; it has 'agreement' or 'slashes' in the filename Each datafile has NetCDF attributes which clearly describe the data. CMIP6 is the sixth phase of the Coupled Model Intercomparison Project. 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.
