(TGICA) and IPCC Data Distribution Centre within the IPCC structure
The Task Group on Data and Scenario Support for Impact and Climate Analysis (TGICA) facilitates distribution and application of climate change related data and scenarios to enable research and sharing of information across the three IPCC Working Groups (Figure 1). The conduct of TGICA is governed by its mandate.
The IPCC Task Group on Data and Scenario Support for Impact and Climate Analysis (TGICA) was established in 1996. It comprises members with expertise and experience drawn from a cross section of research communities representing all three IPCC Working Groups.
TGICA oversees a Data Distribution Centre (DDC) which provides data sets, scenarios of climate change and other environmental and socio-economic conditions, and other materials (e.g. technical guidelines on the use of scenarios and fact sheets offering clarifying explanations/concise guidance on topical issues). The DDC also links to relevant data sets and information held outside the DDC, such as outputs produced from the new community-led process of scenario development to support climate change research. The DDC managers conduct regular surveys of users, with results from the most recent in 2015 reported here.
TGICA also contributes to building capacity in the use of data and scenarios for climate-related research in developing and transition-economy regions and countries. It does this through the data and guidance provided via the DDC, by convening expert meetings on an as-needed basis, and by maintaining and updating a global list of networks for outreach.
Since TGICA was established in 1996, a great deal has changed regarding needs and services for data and scenarios. Most significantly, the community of users has evolved from a relatively small group of researchers focusing on global- and regional-scale modelling of the impacts of climate change, to a large and diverse set of actors worldwide, including national, state/provincial, and local entities, business and industry, non-governmental organizations, and community groups. This more diverse group of users has a far more varied set of data and scenario needs, including data products more appropriate to settings with limited computational, communications, and research capacity. The process for preparation of scenarios has also changed, and has become a more open, interdisciplinary process with a larger number of interactions across the climate modelling, impacts/adaptation/vulnerability, and integrated assessment modelling communities. These changes provide new challenges and opportunities for TGICA.
TGICA Membership was refreshed in the summer of 2010 (see table below) with Timothy Carter (Finland) and Bruce Hewitson (South Africa) appointed in May 2011 to serve as Co-Chairs.

Considering the rapidly changing landscape of climate data and scenario information, the IPCC decided at its 41st Session to revisit the mandate of TGICA ahead of the upcoming Sixth Assessment. It invited government comments on a Vision document for TGICA and the DDC and arranged an Expert Meeting on TGICA (26-27 January 2016). The TGICA Co-Chairs were invited to revise the Vision document in preparation for the 43rd Session.
Documents of relevance to the future of TGICA and the DDC include:
- Options for Discussion and Decision on the Future Role of TGICA [IPCC-XLIII/Doc. 10, Corr.1]
- This document sets out some alternatives for decisions on the future of TGICA and the DDC, including revisiting the TGICA mandate, TGICA, membership, resourcing of TGICA and resourcing of the DDC. It also summarises priority objectives for TGICA and the DDC that are detailed in a separate document.
- Priority objectives for TGICA and the Data Distribution Centre (DDC) [IPCC-XLIII/INF. 17]
- This document presents a classification of activities currently or potentially undertaken by TGICA and the DDC. Activities have been prioritized both according to need as well as to resource requirements, based on expert input concerning the relative importance attached to different TGICA/DDC activities and taking account of whether activities are internal or external to IPCC.
- Expert Meeting on the Future of the Task Group on Data And Scenario Support for Impacts and Climate Analysis (TGICA): Summary [IPCC-XLIII/Doc. 10, Corr.1]
- This summary was prepared by the IPCC Secretariat and Co-Chairs and Steering Committee of the Expert Meeting and presented at the 51st Session of the Bureau (16-17 February 2016).
- Expert Meeting on the Future of the Task Group on Data And Scenario Support for Impacts and Climate Analysis (TGICA) (Full Report)
- This is the full report of the Expert Meeting prepared by the IPCC Secretariat with input invited from all participants.
- TGICA Vision Paper (August 2015) [EXMOT/Doc4]
- This document presents perspectives of the Task Group membership on the future of TGICA as the IPCC enters the next cycle, also incorporating feedback received at IPCC 41 and subsequent discussion at TGICA-22 in New York (June 2015). Three options are presented for the future of the TGICA and the Data Distribution Centre (DDC) it oversees: (1) Discontinue or severely curtail TGICA and discontinue the DDC; (2) maintain the status quo; or (3) strengthen TGICA and upgrade the DDC. Each of these options carries with it organisational and resource implications.
- Governments and International Organizations comments on TGICA Vision Paper [IPCC-XLIII/INF. 18, IPCC-XLIII/INF. 18, Add. 1]
- These documents are a compilation of comments on the TGICA Vision Paper by governments and international organizations received in advance of the IPCC Expert Meeting on TGICA.
- Institutional Analysis of TGICA [link]
- This document was prepared as an independent analysis of TGICA and the Data Distribution Centre in the context of a changing global environment of climate change related data and information. It was drafted by Catherine Vaughan of the International Research Institute for Climate and Society, Columbia University ahead of the IPCC Expert Meeting on TGICA, with funding from the Finnish government. Using TGICA documents, related literature and interviews of key persons associated with TGICA in the past and present, the report takes stock of the main contributions of the Task Group and crystallizes some of the persistent challenges that have limited its efficacy. The report also reviews trends that have shaped the environment in which TGICA operates and considers opportunities for TGICA to contribute in a unique way within this new environment.
