Aquarius is an L-band instrument designed to measure sea surface salinity from space. The instrument was launched in 2011 and data acquisition ended in June 2015 when control of the spacecraft was lost. Aquarius produced global maps of salinity with accuracy of 0.2 psu and special resolution of 150 km as well as other products such as global maps of RFI and soil moisture. The mission will formally...
Aquarius is a radiometer/scatterometer combination specifically designed for remote sensing of sea surface salinity. The instrument was launched on June 10, 2011 as part of the Aquarius/SAC-D observatory. The observatory and all instruments were lost on June 7, 2015 when a power failure on the satellite resulted in loss of control of the observatory. Mission operations have ended and the Aquarius...
Two ongoing space missions share the scientific objective of mapping the global Sea Surface Salinity (SSS), yet their observations show significant discrepancies. ESA's Soil Moisture and Ocean Salinity (SMOS) and NASA's Aquarius use L-band (1.4 GHz) radiometers to measure emission from the sea surface and retrieve SSS. Significant differences in SSS retrieved by both sensors are observed, with SMOS...
Aquarius is an L-band instrument designed to map the surface salinity field of the global oceans. It consists of three L-band (1.41 GHz) radiometers and an L-band (1.26 GHz) scatterometer. The radiometers are the primary instruments for measuring salinity and the scatterometer provides a correction for surface roughness. Aquarius was launched in June 2011 and has been mapping the surface salinity...
The third Stokes parameter will be observed from space for the first time at L-band by the Soil Moisture and Ocean Salinity and Aquarius/SAC-D satellites. The correlation between polarizations, which is the source of the third Stokes parameter, is of interest at L-band to measure Faraday rotation and also to indicate novel features of the surface. However, spurious signals (false indication of correlation)...
The Aquarius instrument is a pathfinder to demonstrate the measurement of sea surface salinity (SSS) from space. The goal is to measure SSS with an accuracy of 0.2 practical salinity units (psu) and spatial resolution of 150 km, globally each month. To achieve this high accuracy in SSS, the radiometer requires accurate radiometric calibration. As part of the calibration plan it is planned to look...
