The Atlas builds on several key observational and model simulated datasets made publicly available by different institutions and modeling centers, in some cases resulting from international collaborations such as CMIP and CORDEX. It also includes some datasets used in different chapters of AR6 WGI report.
The observational datasets used in the Atlas are described in Table Atlas.SM.15. This repository contains information derived from the W5E5 (WFDE5 over land merged with ERA5 over the ocean).
An inventory of the data sources of the model simulations used for the different experiments and scenarios is included here, indicating the availability of the different variables as well as auxiliary fixed fields, such as the land/sea mask (sftlf). The following documents provide a full overview of the simulations available:
Full metadata is organized as machine-readable tables in the different CMIP5, CMIP6 and CORDEX folders. This includes the ESGF version used for each model and variable so the data is fully traceable. CMIP6 includes different temporal frequencies (day/mon) and realms (atmos, land, ocean, seaIce). The data consolidated here is a subset of the data available at ESGF for the relevant experiments used. README files in the different folders provide handle and/or ESGF search links pointing to the specific datasets used.
Dataset_DOIs.html contains a searchable table with the DOIs for all datasets that provide them. Dataset DOIs provide provenance information at the dataset level. This table feeds from the dataset_table.csv in metaclipcc.
Note:
This folder traces the exact version of the datasets used in the Atlas. Newer versions of these data may exist in the future for different reasons. Users should visit the ES-DOC Dataset Errata website (https://errata.es-doc.org) to check the availability of newer versions or data retractions in the datasets stored in this repository.
Broadly speaking, throughout this repository the term CMIP6 has been used mostly in reference to the Scenario Model Intercomparison (ScenarioMIP). However, please note that other CMIP6-Endorsed MIPs are also included here, namely CORDEX (Coordinated Regional Climate Downscaling Experiment) and PMIP (Palaeoclimate Modelling Intercomparison Project). https://doi.org/10.5194/gmd-11-3659-2018
The paleoclimate simulations used in the Interactive Atlas were generated by Dr Chris Brierley using model simulated data from PMIP3 (CMIP5) and PMIP4 (CMIP6) experiments. The data and code are available in the PMIP_for_AR6_Interactive_Atlas WGI GitHub repository.
Sea level rise information was obtained directly from Chapter 9.
Information on surface Ozone, Particulate Matter (PM2.5), and Effective Radiative Forcing (ERF, due to aerosols) was obtained directly from Chapter 5.
We acknowledge all institutions and modeling centers for making the data publicly available.
