Satellite Mission to Study Ocean Salinity and the Global Hydrological Cycle: 4th Aquarius/SAC-D Science Workshop; Puerto Madryn, Argentina, 3–5 December 2008



Important aspects of climate change in the 21st century will involve interactions between ocean circulation and the global hydrological cycle, and their links to land surface hydrology, the cryosphere, the atmosphere, and other realms. The Aquarius'Satelite Aplicaciones Cientificas-D (SAC-D) satellite mission is a multidisciplinary observatory that will provide measurements of ocean salinity, ocean winds, rain, sea ice, land'sea surface temperatures, soil moisture, nighttime light sources, atmospheric temperature'humidity soundings, and the space environment, as well as autonomous data relay from remote ground stations. Scheduled for launch in May 2010, the project involves international contributions by Argentina, the United States, Italy, Canada, France, and Brazil, and has an active public awareness and education program (see and
