Understanding and predicting changes in the world’s water and climate by bringing together scientists globally.

Our mission is to observe, understand, and model the hydrological cycle and energy fluxes in the Earth’s atmosphere at and below its surface.

The Global Energy and Water Exchanges (GEWEX) program is a core project of the World Climate Research Programme (WCRP). We are a network of scientists gathering information on the global water and energy cycles through research, observations, and science activities, which will help to predict changes in the world’s climate.

Our GEWEX scientists conduct research on the many elements of the global water cycle to help fine-tune our understanding of them and their impact on the climate, humans and the environments we live in.

GEWEX also points out important gaps in knowledge and implements ways to fix those gaps, whether through new studies, reviews of datasets, gatherings of experts, or other opportunities.
