 # IPCC AR6 Chapter 9 Figures
-### Repository with the code and data for all figures from Chapter 9 of the Sixth Assesment Report from the Intergovernmental Panel on Climate Change (IPCC AR6)

 ## How to use this repository
 The code to plot each figure from Chapter 9 of IPCC AR6 is contained in the [`Plotting_code_and_data`](https://github.com/BrodiePearson/IPCC_AR6_Chapter9_Figures/tree/main/Plotting_code_and_data) directory. 
 Each figure has its own folder, named after its number in the report and a brief descriptor of the figure.

 As a result, we have reproduced these plotting codes to read and use the IPCC/CEDA-formatted _plotted datasets_, with a caveat that maps use a different hatching technique. There are two routes if you wish to replot these data-intensive figures:
 1. **Use the codes suffixes `_from_metadata.m`, which are the codes linked in the Table below.** .These plots are identical  to the AR6 plots, except for low confidence hatching which is replaced by stippling (it was not trivial to get the hatching function used for the report to work with the masked data format of the saved data). 
 2. **Download required data & run the original code.** Download and collate the required datasets (for example from ESGF nodes), and use the original calculation and plotting codes for these particular figures. The metadata of CMIP datasets and other datasets used within the figures are provided in the Appendix for Chapter 9 of IPCC AR6, and in the supplementary material from the IPCC TSU. The directory structure of this data can be inferred from the code in the repository.
