Upper ocean salinity stratification and rain freshening in the tropics observed from Aquarius
2014
2014 IEEE Geoscience and Remote Sensing Symposium
Preserved Fulltext
As the measurements occur at different depth below the ocean surface, this allows an assessment of salinity stratification within the very upper ocean layer and rain induced freshening effects. ...
We present validation results for the Aquarius Version 3.0 ocean surface salinity product that has been released in June 2014. ...
Another possible source for SST dependent biases is the surface roughness correction: For example, the SST dependence of the wind induced emissivity that has been assumed in [6] and [10] is likely ...
