Scientific Steering Group

The GEWEX Scientific Steering Group (SSG) guides the formation of GEWEX’s scientific program, and is comprised of scientists from across the world who study issues related to the global water and energy cycles. In addition to monitoring and shaping the course for GEWEX, the SSG briefs the Joint Steering Committee of our parent organization, WCRP, on progress made within GEWEX and general advances in understanding in our areas of scientific expertise.

Information on current and past SSG meetings can be found at GEWEXevents.org.
