    • Sea surface salinity measured by satellites is the value estimated remotely and indirectly using electromagnetic waves．The estimated value must be validated by comparing it with observation data from the field.

      The comparison and validation with the observation data by the Argo floats showed that the satellite and field salinity values were comparable. It was also shown that the satellite salinity deviates greatly from the field salinity in high-latitude regions where the water temperature is low．

      This result suggests that the salinity sensitivity of microwaves varies depending on the sea area.
