Why is it Important to Measure Salinity With Both In-Situ and Satellite Instruments?
In-situ instruments are more traditional, while salinity measurements obtained from space still need certain levels of validation and calibration before they can be fully "stand-alone" to the same degree of reliability. In order to understand all of the processes affecting ocean salinity (3-D and 4-D) you need both types of measurements to get a more detailed picture. Featured Video: Salinity From Space is Awesome
