Objective
The project aims at theoretical and experimental study of the long surface waves interaction with the short wind waves. The addressed problem is of highly importance for an adequate modelling of the wave-radar Modulation Transfer Function (MTF) to improve algorithms used to infer wave and wind parameters from satellite remote sensing data.
To achieve the goal the main objectives are defined as:
1. To build a model of the short wave modulation by long surface waves, and to incorporate this model into the hydrodynamic component of the wave-radar MTF;
2. To obtain experimental estimates of the short wind wave modulation by long waves based on in-situ wave records, aircraft microwave radar and optical images, to be collected during the FETCH experiment. To verify a new wave-radar MTF model against the FETCH experiment field data;
3. To improve theoretical background of algorithms used to retrieve ocean wave spectra, wind fields, and significant wave heights from advanced on-board satellite radar instruments.
The expected results of this project are:
1. The model of the short wave modulation by long surface waves accounting for aerodynamics of the air flow over the waves, the wind-wave coupling, and the influence of the current shear in the water viscous sublayer;
2. Experimental estimates of the short waves and their mean square slope modulation by long waves based on radar and optical measurements collected during the FETCH field campaign. The conclusion on the applicability of the coupled model to reproduce observations;
3. The assessment of the role of the wind ripple modulation in the existing models of the microwave scattering used in retrieval of the surface waves and winds from the Synthetic Aperture Radar (SAR), scatter meter and altimeter data.
The previous results obtained by Surface Phenomena Researches Group are very promising: for several kinds of developed composite powder materials tool life was prolonged in 10 times with simultaneous metalworking intensification from 2 to 4 times.
It is expected, that these new "self-organizing" tools will have wear resistance comparable with existing ones and a cost 3 times lower.
Cooperation between EU/CCE/NIS in the Frame of the present project will provide means for innovative technology transfer and strengthening the Community's and NIS scientific and technological basis, and reduction in consumption of the strategic materials such as wolfram.
