The IPCC's AR6 WG1 Report published in August 2021 contains a lot of useful data and figures. The data is available at the CEDA Archive under a Creative Commons CC-BY license, but the formats are quite diverse and not easy to handle.

This repository compiles the data into a uniform, csv-based data format following the standard established by the Integrated Assessment Modeling Consortium (IAMC) and used by IPCC WG3.

The format used in this repository is directly compatible with the scmdata and pyam Python packages (see dependencies below), but can be easily read with Excel or scripts written in other programming languages.

This repository contains Jupyter notebooks that replicate several key figures of the IPCC AR6 WG1 report to facilitate reproducibility of the assessment and re-use in subsequent research and analysis.

Please see the notebooks folder for an overview!

The data and notebooks in this repository use the dependencies specified in environment.yml. A high-level overview of the packages is below:

• pyam (note that this package is distributed on pypi as pyam-iamc)
• scmdata
• seaborn
• tqdm
• xarray
• notebook

The required packages can be installed with conda: conda env create -f environment.yml.

The data is compiled using openscm-ar6-wg1-data-compilation compile. This command-line interface takes a single argument, config_yaml, which defines the data sources, which data is expected, where the raw data is stored, where the outputs should be written and also includes relevant metadata. An example is given in the root of this repository in compilation-config.yaml. Once the data is compiled, it will be in the specified output directories and ready for use. TODO: also spit out variables and definitions as part of compilation

For information about the data directories, see data/README.

We are grateful for the terrific work by Robin Matthews, Özge Yelekçi, Melissa Gomis, Lina Sitz, the CEDA Archive and many researchers and WG1 TSU staff in compiling, validating and publishing the data under a license that permits re-use.
