Abstract

The invention discloses a parameterization remote sensing method based on an oxygen A channel aerosol scattering effect. The method comprises the steps that the scattering effect of oxygen A channel aerosol is parameterized, and equivalent statistics is carried out on the scattering effect through four parameter factors; the initial priori values of the four parameter factors are selected, a whole atmosphere layer transmittance calculation equation is corrected through the four parameter factors, and a whole atmosphere layer effective transmittance model is obtained; based on the whole atmosphere layer effective transmittance model with the parameter factors added, the values of the four parameter factors of the aerosol scattering effect are inverted under an actual aerosol observation condition through oxygen A channel observation data and an optimization estimation method; through the four parameter factor values obtained through inversion, the finally-corrected whole atmosphere layer transmittance model is obtained, and the aerosol scattering effect is accurately estimated. A precise and effective technical means is provided for solving an aerosol scattering correction problem existing in the process of carrying out visible light-short wave near-infrared satellite remote sensing in an aerosol high-value area.

Description

technical field [0001] The invention relates to the technical field of satellite atmospheric remote sensing, in particular to a parametric remote sensing method based on the aerosol scattering effect of an oxygen A channel. Background technique [0002] In the 1970s, the United States first designed the satellite sensor HIRS for remote sensing of the atmosphere. In the early days, it was mainly used to detect carbon dioxide and water vapor in the atmosphere and retrieve the temperature profile of the atmosphere. Early sensors mainly used the thermal radiation information of the atmosphere. Due to the long wavelength of radiation in the thermal infrared band, it is not affected by the scattering effect of particles in the process of atmospheric transmission. [0003] Due to the limitation of the characteristics of atmospheric thermal radiation transmission, the thermal radiation observation data of satellite sensors are not sensitive to the parameters of the near-surface atmo...
