Global Energy and Water Exchanges

The Global Energy and Water Cycle Exchanges (GEWEX) a core project of the World Climate Research Programme, is dedicated to understanding Earth’s water cycle and energy fluxes at and below the surface and in the atmosphere. 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.

The International GEWEX Project Office (IGPO) supports these activities by planning meetings, implementing research goals, and producing a quarterly newsletter to keep the GEWEX community informed.

GEWEX coordinates science activities to facilitate research into the global water cycle and interactions between the land and the atmosphere. One of the primary influences on humans and the environments they live in, the global water cycle encompasses the continuous journey of water as it moves between the Earth’s surface, the atmosphere, and beneath the Earth’s surface. Clouds, precipitation, water vapor, surface radiation, aerosols, and other phenomena each play a role in the cycle. Many GEWEX scientists conduct research on those and other elements to help fine-tune our understanding of them and their impact on the climate. 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.
