Hardware and software combined optical earth observation atmospheric correction

Aerosol particles are important components of the earth-atmosphere system, which change the radiance balance of earth-atmosphere system by the two processes of absorption and scattering, also distort the signal of earth observation satellite. For understanding the atmospheric attenuating effect of aerosols to satellite signals, a portable Mie Lidar system is developed, which is mainly used for measuring the optical properties of aerosol. At the same time, a radiative transfer model is introduced for implementing atmospheric correction of satellite signal. The aerosol data from lidar measurement are fed into radiative transfer code, instead of the model transcendental value. The primary results are shown in this paper. Furthermore, long-term atmospheric and aerosol data could be obtained by consecutive lidar observations. Also these data will be used for emending the existing atmospheric model and make it more compliant for China area application.
