Materials on the IPCC FAIR Guidelines implementation and lessons learned provided for the EGU Open Science and Data Help Desk 2023., Materials consist of a one-pager, a video recording of a demonstration and the script of the recording.

Annual Report of the IPCC Data Distribution Centre (DDC) Partner DKRZ for the year 2022.

This lecture was given at the "IS-ENES3 Summer School on Data Science for Climate Modelling", 1-7 September 2022. It introduced the lectures on data management based on the practice example of the IPCC FAIR Guidelines, which had been developed for the Sixth Assessment Report (AR6).

This report provides statistics on the data downloads from the Reference Data Archive for climate model output hosted at the IPCC Data Distribution Centre (DDC) at DKRZ (http://ipcc.wdc-climate.de) for 2021.

The Memorandum of Understanding commits the partners to working together to meet the objectives which have been set out for the DDC at the 47th session of the IPCC.

The the amount of work and resources invested by the modelling centers to provide CMIP6 (Coupled Model Intercomparison Project Phase 6) experiments and climate projection datasets is huge, and therefore it is extremely important that the teams receive proper credit for their work. The Citation Service makes CMIP6 data citable with DOI references for the evolving CMIP6 model data published in the Earth System Grid Federation (ESGF). The Citation Service as a new piece of the CMIP6 infrastructure was developed upon the request from the CMIP Panel.CMIP6 provides new global climate model data assessed in the IPCC's (Intergovernmental Panel on Climate Change) Sixth Assessment Report (AR6). Led by the Technical Support Unit of IPCC Working Group I (WGI TSU), the IPCC Task Group on Data Support for Climate Change Assessment (TG-Data) developed FAIR data guidelines, for implementation by the TSUs of the three IPCC WGs and the IPCC Data Distribution Centre (DDC) Partners. A central part of the FAIR data guidelines are the documentation and citation of data used in the report.The contribution will show how CMIP6 data usage is documented in IPCC WGI AR6 from three angles: technical implementation, collection of CMIP6 data usage information from the IPCC authors, and a report users’ perspective.

The information provided in the Intergovernmental Panel on Climate Change (IPCC; http://ipcc.ch ) Assessment Reports (ARs) inform climate change policy development. Within the IPCC the scientific coordination of the ARs is conducted by three Working Groups (WGs) comprising of the Bureaus supported by their Technical Support Units (TSUs). Data management support is provided by the IPCC Data Distribution Centre (DDC; http://ipcc-data.org ), which is overseen by the Task Group on Data Support for Climate Change Assessments (TG-Data; formerly TGICA). The DDC is a federated structure that is currently managed by the Centre for Environmental Data Analysis (CEDA; http://www.ceda.ac.uk/ ), United Kingdom; the World Data Center for Climate (WDCC; http://www.wdc-climate.de ), Germany; and the Center for International Earth Science Information Network (CIESIN; http://www.ciesin.columbia.edu/ ) at Columbia University, U.S. For the IPCC Sixth Assessment cycle (AR6), analyses of climate simulations and observations published in scientific literature will be assessed. The reports will include figures and tables prepared from the underlying digital information. The DDC plays an increasingly important role in facilitating the exchange of data, as well as curating the assessed datasets, scripts and provenance records to facilitate the assessment process and to support the traceability of AR6 results through long-term continuity of data management and curation. These issues, among others, are addressed by the DDC support group ( https://cedadev.github.io/ipcc_ddc ) currently consisting of members from the three TSUs and the three DDC managers.

This PICO presented at EGU 2017 describes the two services, which DKRZ contributes to the CMIP6/AR6 infrastructure: Data Citation and the IPCC Data Distribution Centre (IPCC DDC) Reference Data Archive of the climate model output / CMIP6 Data Pool.
