摘要

The latest new technology for ex-ploring the ocean from space is to measure sea surface salinity (Figure 1). Utilizing microwave measurements in the L-band (1-2 GHz), the salinity of the upper ~ 1 cm of the surface is derived with sufficient accuracy to map the global field, its seasonal to interan-nual variations, and smaller-scale features associated with major river outflows and ocean current meanders. The data provide many new opportunities for scientific studies of the coupling between changes in the global water cycle, ocean circulation, and climate. This note describes the Aquarius/ SAC-D mission , launched in June 2011, which is a partnership between the United States (NASA) and Argentina . The satellite maps the globe every 7 days with a spatial resolution between 90 and 150 km.
