Joint CCl/WCRP/JCOMM Expert Team On Climate Change Detection And Indices (ET-CCDI)


Terms of Reference

  1. 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 GFCS;
  2. 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;
  3. Further develop and publicize internationally agreed indices of global climate variability and change and their methodologies, with added emphasis on marine climate indices;
  4. Facilitate the use of observational data to evaluate model output and provide guidance on related data and model output requirements for extremes analysis;
  5. 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.

Background information


ET-CCDI workshops

The general goals of ET-CCDI workshops include:

  1. Derive indices from daily data, especially measures of changes in extremes
  2. Fill in blank data areas in "global" analysis of climate indices
  3. Increase confidence in local analyses by placing these analyses in a larger, regional context that includes results from neighbouring stations and countries.
  4. Increase regional research synergies by sharing insights and improve analyses between neighbouring countries
  5. Foster greater appreciation for data and data archeology
