Overview
The outcomes of CMIP, including the peer-reviewed published literature across the community, contribute to assessments and reports from the International Panel on Climate Change (IPCC). The IPCC is an intergovernmental body of the United Nations (UN), charged with advancing scientific knowledge of human impacts on climate change. The IPCC informs governments about the state of knowledge on climate change by synthesising all published literature in Assessment Reports (ARs) every 5-7 years. As such, the IPCC does not conduct its own research but tasks scientists from around with world the conduct comprehensive assessments of peer-reviewed scientific literature. Phases of CMIP have historically been designed to align with IPCC assessment reports.

CMIP data used in IPCC reports
Data, including CMIP simulations, used in IPCC reports is archived in the IPCC Data Distribution Centre (DDC). The IPCC DDC is managed by four partners, the German Climate Computing Center (Deutsches Klimarechenzentrum, DKRZ, Germany), the Center for International Earth Science Information Network (CIESIN, USA), the Spanish Research Council (CSIC, Spain), and MetadataWorks (UK). Of these, DKRZ is the only remaining founding partner and has been involved in operating the DDC for over 25 years, and is the member responsible for the CMIP data used in IPCC.

Data
CMIP6 datasets used as input for the IPCC AR6 Working Group I are available via the input data DKRZ catalogue entry and selected intermediate datasets via the intermediate data DKRZ catalogue entry. Click on ‘Find data’ to search the catalogue records and to access the data. Citation and data license information are available on the data landing pages.
Additionally, much of the data used to create the AR6 WGI figures has been archived by CEDA.
Scripts
The code used to generate many of the figures in AR6 WGI can also be found in the IPCC GitHub repository.
Earlier assessment reports
Climate model data used in previous IPCC reports, including the Special Report on Global Warming of 1.5°C (SR1.5) and AR5 can be found here.
