Basic Idea and New Advance in Atmospheric Correction for Optical Remote Sensing

NIU Zheng (Institute of Remote Sensing Applications, The Chinese Academy of Sciences,Beijing 100101)  
It is indicated that atmospheric correction for optical remote sensing is one of the problems to be solved in urgent need for quantitative remote sensing.The correction results depend on which we employ and their accuracy,such as the model of atmospheric particles,the hypothesis of surface properties,as well as the theory of radiance transfer.Scientists have to balance between a complicated theory and an accurate result.Then,an analysis and summary to those effective factors is submitted comprehensively and in detail.The developing history and the current status of the related researches are described,as well as the direct and indirect correction methods are introduced.It is also reminded that the theory and method of atmospheric correction need a further advance and complement considering their defects in practice.Finally,we conclude a strategy for the atmospheric correction.
