Abstract

The invention is suitable for the technical field of water color remote sensing atmospheric correction, and provides an atmospheric correction method based on satellite remote sensing data, terminal equipment and a storage medium, and the method comprises the steps: obtaining the distribution characteristics of a first wave band aerosol scattering coefficient of a to-be-measured environment and an aerosol scattering coefficient corresponding to a wavelength in a second wave band; according to different distribution characteristics, selecting different processing modes to process the aerosol scattering coefficient corresponding to the wavelength in the second wave band, obtaining the aerosol scattering coefficient corresponding to each wavelength in the first wave band, and performing atmospheric correction based on the obtained aerosol scattering coefficient of the first wave band; according to the invention, different processing modes are selected according to the environment to be measured to obtain the aerosol scattering coefficient of the first wave band, the obtained aerosol scattering coefficient of each wavelength in the first wave band is more accurate, and the accurate aerosol scattering coefficient of each wavelength in the first wave band is used to correct the atmosphere, so that the atmosphere correction is more accurate.

Description

technical field [0001] The application belongs to the technical field of water color remote sensing atmospheric correction, and in particular relates to an atmospheric correction method based on satellite remote sensing data, a terminal device and a storage medium. Background technique [0002] Aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gaseous medium. With the development of ocean water color remote sensing technology, the requirements for the accuracy of atmospheric correction are getting higher and higher, and one of the key factors affecting the accuracy of atmospheric correction is the aerosol scattering coefficient. [0003] At present, the research on the aerosol scattering coefficient mostly focuses on the aerosol scattering coefficient in the ultraviolet band and the short-wave infrared band. The aerosol scattering coefficient of the visible light band is inferred to obtain the aerosol scattering coefficient o...
