Oceans and climate change: The future of spaceborne altimetry



Oceans and polar ice sheets are dominant elements of the climate system and require global observations to understand their role in climate changes. As repeatedly demonstrated over the past 2 decades, satellite altimetry is a unique powerful technique for providing global information on ocean circulation and ice sheet volume. “Oceans and Climate Change: The Future of Spaceborne Altimetry,” written by an international team of scientists, was recently published by the Joint Oceanographic Institutions. It summarizes the objectives and requirements for future altimetric missions in the context of global change research and defines the mission constraints and technical capabilities for achieving these measurements. This short note summarizes the major points of the report.
