AQUARIUS SATELLITE SALINITY MEASUREMENTS; PRELIMINARY RESULTS OF THE FIRST SIX MONTHS

The US-Argentine Aquarius/SAC-D satellite was launched June 10, 2011 with a suite of sensors for Earth observation and a primary mission to monitor global variations in ocean surface salinity to study the links between ocean circulation, water cycle and climate. Measurements include salinity, wind, rain, surface temperature, sea ice, soil moisture, night images, atmospheric soundings and space environment, coupled with an active educational program. At the time of this writing, the Aquarius sensor has collected ocean salinity data since late August 2011, and initial unvalidated data have been released for evaluation. Aquarius samples the global ocean surface salinity field every seven days and is designed to achieve 0.2 psu accuracy over monthly averages on 150 km spatial scale. The data already show very robust signatures of the basin scale salinity patterns and many details on sub-basin scales. This presentation will provide an early review of the first six months of salinity data, including the status of calibration and validation, ancillary wind and other corrections, a description of the resolvable salinity variations and other notable findings in the initial measurements.
