China Sea observed by the mmwave channel of FY3 MWRI, explains the reason\nfor which the analysis method combined with multiple mmwave channels\nis conducive to wind inversion, uses the complex model of the two-scale randomly\nrough surface with foam scattering layer to calculate the backward heat\nemission, analyzes the different response characteristics of the thermal radiation\ncharacteristics of each channel with the change of the sea surface wind\nspeed, and establishes the wind speed inversion model applying to the microwave\nradiometer, achieving better results than in previous studies. The sea\nsurface medium-low wind speed precision standard deviation of new model\nreaches 1.2 m/s (0 - 15 m/s); the inversion strong wind data are consistent\nwith the island fixed buoys data, and the global sea surface wind speed image\nschematic diagram is given.
