The Expert Team on Climate Change Detection and Indices (ETCCDI) has sunset.
At the seventeenth session of the WMO Commission for Climatology (CCl-17, 2018), it was decided that the group activities of ETCCDI would discontinue. The CCl Expert Team on Sector-specific Climate Indices (ET-SCI) would be responsible for operational aspects of enhancing software tool for sector-specific climate indices.
The WCRP Grand Challenge on Weather and Climate Extremes has integrated much of the research aspects of ETCCDI, global dataset development and detection and attribution. Particular emphasis is being made to ensure contributions to the development of extremes-related climate services.
The joint CCl/WCRP/JCOMM Expert Team on Climate Change Detection and Indices (ETCCDI) has the mandate to address the need for the objective measurement and characterization of climate variability and change. The team provides international coordination and collaboration on climate change detection and the indices relevant to climate change detection, and encourages the comparison of modelled data and observations.
Terms of Reference
- Coordinate, organize, and collaborate on climate extremes, indices and climate change detection, including the WCRP “Grand Challenge on Extremes” activities and contributions to the development of extremes-related climate services in support of the Global Framework for Climate Services (GFCS);
- Encourage and facilitate the development of national and international datasets to support research and services related to climate extremes and land and ocean data management and rescue efforts;
- Further develop and publicize internationally-accepted indices of global climate variability and change and their methodologies, with added emphasis on marine climate indices;
- Facilitate the use of observational data to evaluate model output and provide guidance on related data and model output requirements for extremes analysis;
- Coordinate relevant regional activities, e.g. the calculation and exchange of indices, through regional workshops and, on a routine basis, through regional centres and the International Climate Assessment & Dataset (ICA&D) initiative.
