Joint CCl/Clivar/JCOMM Expert Team On Climate Change Detection And Indices

Terms of Reference:

  1. Provide international coordination and help organize collaboration on climate change detection and indices;
  2. Further develop and publicize indices and indicators of climate variability and change and related methodologies, from the surface and subsurface ocean to the stratosphere, with international consensus;
  3. Encourage the comparison of modeled data and observations, perhaps via the development of indices appropriate for both sources of information;
  4. Coordinate these and other relevant activities the ET chooses to engage in with other appropriate working bodies including of those affiliated under OPACE-4, WCRP and JCOMM as well as others such as GCOS, CBS, CIMO, CAgM, CHy, IPCC and START; and regional associations;
  5. Explore, document and make recommendations for addressing the needs for capacity-building in each region, pertinent to this topic with consideration of the GFCS requirements; and
  6. Submit reports in accordance with timetables established by the OPACE 2 co-chairs with the main deliverables being the provision of a review report on the existing indices, a peer-reviewed guidelines on new climate indices; and the development of new strategy for ETCCDI workshops considering the requirements of the GFCS and the contribution to the IPCC 5AR.

Workshops on Extremes Indices

The general goals of the 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
