Calculation of Atmospheric Transmissibility of MODIS Data Under Different Levels of Meteorological Visibilities
基于MODIS数据的典型能见度条件下大气透过率计算

In this article,6S model was used to calculate the satellite observing reflectivity and radiability above ocean surface with typical oceanic aerosol parameters selected.The result shows that some obvious errors will be induced when visibility drops under 5km.Then a synthetic influence on radiation transmission of aerosol and vapor was considered in the radiation transmission model and equations between whole layer transmissibility and planet reflection was built.Three days of MODIS(moderate resolution imaging spectroradiometer)data corresponding to high visibility,moderate visibility and low visibility were taken for calculation.The result shows close accordance with the observed visibility of the time.This study gives an applicable methodology for transmissibility calculation under different atmosphere condition and provides a potential method for quantitative visibility motoring with remote sensing.
