A Novel Ocean Scatterometer for Simultaneous Measurements of Marine Winds and Surface Currents
Presentation from Dr Franco Fois, of Airbus Defence and Space.
The general circulation of the ocean is driven horizontally and vertically by two main mechanisms that are closely linked: wind-driven circulation and density-driven thermohaline circulation.
Measurements of ocean surface currents are essential to a large number of scientific and societal issue,s and are essential to our understanding of ocean circulation at all time and space scales.
Satellites provide a wide range of data that can, in principle, be used to generate surface ocean current maps at different time and spatial scales, depending on the techniques used.
Radar scatterometers are designed to measure wind speed and direction from ocean radar backscatter, but these instruments were not designed for Doppler measurements. Therefore, new observation principles and data processing techniques must be developed and validated.
This presentation explains and illustrates these new observation principles and data processing techniques.
