A group of selected scientists - the CliC Scientific Steering Group (SSG) - has the overall responsibility for planning and guiding the CliC project. Its members are appointed by the Joint Scientific Committee (JSC) of the World Climate Research Programme, based on recommendations by the CliC SSG. The Chair (or Co-chairs) is responsible for recommending changes in SSG membership to the JSC. Initial membership is for three years and, as a rule, two extensions of two years each may be recommended. The SSG usually meets once a year.
As co-sponsors of the project, the International Arctic Science Committee (IASC) and the Scientific Committee on Antarctic Research (SCAR) are responsible for ensuring that the interests of their organizations are represented on the SSG by at least two members each who could act as liaisons between the co-sponsors and WCRP-CliC.
The organizational needs of CliC are served by the CliC secretariat, located at the Norwegian Polar Institute in Tromsø, Norway.
