Abstract:

Based on the aerosols spatial distribution and the near effect of the earth's surface, the paper studies the influence of different calibration files for spectral reflectance, determines appropriate calibration information, takes into account humidity, and determines reasonable visibility through spectral analysis. These values are used in the calculation of atmospheric correction to improve precision of atmosphere correction. The results show that they can effectively reduce the effects of air molecules, water vapor, aerosol particles, and ozone on the satellite remote sensing images, and improve remote sensing information inversion accuracy in the rocky desertification area. The performance of this method is better in winter than in autumn and spring.

Key words: atmospheric correction, inversion accuracy, remote sensing image, rocky desertification
