Abstract

Abstract Based on radiative-transfer model calculation, it is found that except for very heavy loading of atmospheric aerosols, the spectral reflectance observed by space-borne sensors could be expressed as the function of aerosol optical depth and surface spectral reflectances in some simple forms. On the other hand, the surface spectral reflectances for different surface types have their respective characteristic patterns, which will be used to relate spectral reflectance of one wavelength to others. In this paper, we will discuss the feasibility of simultaneous remote sensing of atmospheric aerosol spectral optical depth and surface spectral reflectances with space-borne spectral sensor. Preliminary numerical simulation showed that it is possible, at least for some simple cases.
