Abstract

The invention relates to the technical field of sea exploration, particularly to a multi-parameter step-by-step sea surface salinity inversion method and device. The method comprises the following steps: obtaining the backscattering coefficient of an L waveband of a target sea surface area through a satellite-borne microwave scatterometer, and carrying out wind speed inverse operation according to the backscattering coefficient and NWP (Numerical Weather Prediction) wind speed information to obtain sea surface wind speed information; obtaining the sea surface radiation brightness temperature information of a C / K waveband through the satellite-borne microwave scatterometer, carrying out temperature inversion operation according to the sea surface radiation brightness temperature information to obtain sea surface temperature information; and substituting the sea surface wind speed information and the sea surface temperature information into a forward direction radiation model of the L waveband to carry out salinity inversion operation to obtain sea surface salinity information. The method can utilize load carried by a sea salinity satellite to independently carry out inversion on sea surface wind speed, sea surface temperature and sea surface salinity, dependency on external auxiliary data by sea surface salinity inversion is solved, and the accuracy of a salinity result is finally improved.

Description

technical field [0001] The invention relates to the technical field of ocean detection, in particular to a multi-parameter and step-by-step sea surface salinity inversion method and device. Background technique [0002] Sea surface salinity is one of the important parameters describing the state of the ocean. Studying its change and distribution is of great significance for analyzing the characteristics of the ocean itself and understanding the role of the ocean in the complex air-sea system. Moreover, sea surface salinity is also an important research object in other disciplines and application fields such as meteorology, ecology, hydrology and fishery. [0003] In the process of studying sea surface salinity, it is first necessary to obtain sea surface salinity; at present, obtaining sea surface salinity is generally obtained by inversion method. There are several current inversion methods. For example, the ocean salinity inversion of the European SMOS satellite first el...
