Satellite Instruments
Aquarius is a focused satellite mission to measure global Sea Surface Salinity (SSS). Scientific progress is limited because conventional in situ SSS sampling is too sparse to give the global view of salinity variability that only a satellite can provide. Aquarius will resolve missing physical processes that link the water cycle, the climate, and the ocean. Aquarius is planning to launch in 2009. Aquarius/SAC-D is a space mission developed by NASA and the Space Agency of Argentina (ComisiĆ³n Nacional de Actividades Espaciales, CONAE.) The science instruments will include a set of three radiometers that are sensitive to salinity (1.413 GHz; L-band) and a scatterometer that corrects for the ocean's surface roughness. The spacecraft will be contributed by Argentina's ComisiĆ³n Nacional de Actividades Espaciales (CONAE). Aquarius will provide monthly maps of sea surface salinity to an accuracy of 0.2 psu (practical salinity units) at a resolution of 150 km. A three-year life time is planned.
