Abstract

The invention relates to an MCC (Maximum Correlation Coefficient) ocean surface current inversion method. The method comprises the steps of preprocessing an MODIS (Moderate Resolution Imaging Spectroradiometer) satellite; performing cloud coverage detection by utilizing a comprehensive optimization cloud detection algorithm; for a clear sky, selecting ocean surface temperature and 550nm reflectivity data as tracers, and performing MMC inversion to obtain an ocean surface current field; for ocean surface current data missing to be measured, performing interpolation replenishment by utilizing a DINEOF (Data Interpolating Empirical Orthogonal Functions) method; and performing variational assimilation optimization adjustment to obtain short-time mean surface current. The method has the beneficial effects that the cloud detection method proposed by the invention improves the identification accuracy of low clouds of sea surface, broken clouds and partial cloud-covered picture elements, removes interferences for calculating the ocean surface current in next step more accurately, and ensures the precision of subsequent results. The interpolation based global optimization adjustment method for the ocean surface current field, proposed by the invention, greatly expands the coverage range of inversion results, remarkably enhances the inversion precision, and extends the application range of the inversion method.

Description

technical field [0001] The invention belongs to the field of satellite remote sensing applications, and in particular relates to an MCC surface ocean current inversion method. Background technique [0002] Ocean currents affect and restrict various physical, chemical, biological, and geological processes in the ocean, as well as the formation and change of climate and weather over the ocean. Therefore, understanding and mastering the laws of ocean currents is beneficial to fisheries, shipping, and sewage discharge. important meaning. For example: ocean currents transmit heat from low latitudes to high latitudes, heat and water vapor are transported upwards over the warm currents, making stratification unstable, air humidity increases and precipitation is easy to occur, cold currents produce temperature inversions, stratification is stable, and water vapor is difficult to transport upwards. Evaporation is weak, and although the relative humidity in the lower layer is sometim...
