Aerosol particles, water vapor and clouds are the three important factors that affect the signals received by sensors. To remove the aerosol effect, some methods have been developed. MODIS aerosol products provided by NASA are based on the Dark Dense Vegetation (DDV) algorithm. The Synergy of Terra and Aqua MODIS (SYNTAM) method is developed recently that can be used to retrieval aerosol optical thickness...
The satellite remote image is degraded obviously due to the diffraction-limitation of imaging system and the atmosphere turbulence and etc.. Namely, the observed image blurred by a low-pass filter whose transfer function vanishes beyond imaging system cut-off spatial frequency (omegac ).Processes that achieve the recreation of frequencies beyond the image pass- band are usually referred to as super-resolution...
An aerosol retrieval algorithm is currently under development in scope of the upcoming APEX hyperspectral imager. It will be able to close the gap between global remote sensing and one-dimensional in situ measurements of atmospheric particles. This paper presents a feasibility study of the proposed APEX aerosol retrieval approach for hyperspectral imagery with high spatial resolution. The extraction...
