The Joint Scientific Committee (JSC) of the World Climate Research Programme (WCRP) provides scientific guidance in all aspects of the World Climate Research Programme, in line with the overall aims and interests of the sponsoring organizations.

For the upcoming membership term, from January 2019 to December 2022, (self-)nominations are sought from the global climate research community. JSC members are to be selected for their scientific knowledge, capability and breadth of vision. The JSC aims to be an inclusive source of leadership for international climate research and seeks nominations of mid- to senior-career researchers from around the globe. The deadline to submit nominations is 6 April 2018.

The membership of the JSC shall aim to include a balanced representation of relevant disciplines in atmospheric, oceanic, hydrological and polar sciences. The JSC guides the overarching objectives and priorities of WCRP, in agreement with the sponsoring organizations and the WCRP sponsors’ agreement (subject to any future revisions thereof through the sponsoring organizations), as well as in line with the upcoming WCRP Strategic and Implementation Plans.

Target expertise:

• Climate Policy
• Climate Services
• Climate Risk
• Scenario Development
• Tropical Climate
• Climate System Modelling
• Sea level Change
• Seasonal Prediction
• Decadal Prediction
