Can Aquarius salinity data be reliably used for near-shore, coastal and estuarine applications?

Thanks for your inquiry regarding Aquarius salinity data and their
potential applicability to coastal applications. Pointers to all Aquarius
data and technical documentation resources at the PO.DAAC are available at .
The Aquarius/SAC-D mission was designed with a principal focus on oceanic
salinity observation. The lower spatial resolution of the Aquarius data (1
degree Lat/Lon for L3 gridded data and about 70x70km for L2 swath/orbital
data), 7day repeat cycle and some technical issues associated with salinity
retrieval near land ("land contamination" and in some areas also "RFI
interference") limits the potential applicability of Aquarius data for
near-shore areas. While improvement of salinity retrieval algorithms
nearer-shore is of interest and the subject of ongoing development efforts
by the Aquarius Science team, application of Aquarius data for coastal and
estuarine studies poses challenges and thus should be considered a future
research area. Aquarius data currently is best suited to the study of
larger scale oceanographic and river plume features (eg. Amazon outflow, Mississippi R. flooding events -see ... 5/abstract).
