Abstract

The invention discloses an aerosol remote sensing inversion method and an aerosol remote sensing inversion system for lack of short-wave infrared data. The aerosol remote sensing inversion method considers the influences of angle and surface type of the earth on a band relationship, constructs a band regression coefficient lookup table for angled grid division and surface feature type classification by using a multi-angle data set, and performs inversion to obtain aerosol optical thicknesses of surfaces of different surface feature types. The method introduces an aerosol correction index (ACI)and NDVI seasonal variation characteristics as limiting conditions for the problem that the aerosol optical thickness inversion results are highly sensitive to the relationship between bands. The core technology of the aerosol remote sensing inversion method is that an aerosol optical thickness lookup table and the band regression coefficient lookup table are established based on the direct correlation of the surface feature spectral bands by combining with influences of different solar observation angles on the band relationship, can rapidly and precisely obtain the aerosol optical thicknessinversion results of different surface features through inversion by screening conditions, and improves the operation efficiency and inversion precision by adopting the above technical means.

Description

technical field [0001] The invention belongs to the technical field of remote sensing image processing, and in particular relates to an aerosol remote sensing inversion method and system for no short-wave infrared band data, and rapidly inverts to obtain high-resolution aerosol optical thickness products. Background technique [0002] Aerosol optical depth is an important geophysical parameter for the study of atmospheric pollution, aerosol radiation, atmospheric correction, etc. Satellite images can be used to monitor aerosol changes on a large scale and explain the impact of aerosols on the earth and the atmosphere on a spatial scale. Satellite remote sensing images contain information on the surface and the atmosphere, and the two interact with each other. The aerosols in the atmosphere lead to the loss of image details and large errors in the quantitative inversion of real information on the surface, also because of the influence of surface information. It also brings di...
