WCRP has the following major projects:
Coordinated Regional Climate Downscaling Experiment (CORDEX): The CORDEX vision is to advance and coordinate the science and application of regional climate downscaling through global partnerships.
- Climate and Cryosphere (CliC): CliC encourages and promotes research into the cryosphere in order to improve understanding of the cryosphere and its interactions with the global climate system, and to enhance the ability to use parts of the cryosphere for detection of climate change.
- Climate and Ocean Variability, Predictability and Change (CLIVAR): CLIVAR’s mission is to understand the dynamics, the interaction, and the predictability of the coupled ocean-atmosphere system. To this end it facilitates observations, analysis and predictions of changes in the Earth's climate system, enabling better understanding of climate variability, predictability and change.
- Global Energy and Water Exchanges (GEWEX): GEWEX is an integrated program of research, observations, and science activities that focuses on the atmospheric, terrestrial, radiative, hydrological, coupled precesses, and interactions that determine the global and regional hydrological cycle, radiation and energy transitions and their involvement in global changes.
- Stratosphere-troposphere Processes And their Role in Climate (SPARC): SPARC coordinates international efforts to bring knowledge of the stratosphere to bear on relevant issues in climate variability and prediction.
