Description

technical field [0001] The present invention relates to the technical field of computer applications, in particular to a data processing method, device and system based on an atmospheric radiation transfer model. Background technique [0002] In recent years, satellite remote sensing images have been widely used. However, since satellite remote sensing images may have some distortion, it needs to be corrected. For users, the method of absolute radiation correction is mainly the atmospheric radiation transfer model method, which is a method of correcting remote sensing images using a model established based on the principle of electromagnetic wave radiation transfer in the atmosphere, with high correction accuracy. Due to different assumptions and scope of application, there are many optional models, such as 6S model, LOWTRAN model, MODTRAN model and ATCOR model. [0003] The current calculation program of the atmospheric radiative transfer model can only process one piece ...
