Influence of atmospheric model and aerosol type on radiation transfer calculation

The selection of atmospheric model and aerosol type is very important in the radiation transfer calculation of quantitative remote sensing. However, the selection is commonly empiric, and its influence on the calculation is usually neglected. Thus a method based on the measurement of sun photometer was proposed to study the selection of atmospheric model and aerosol type. Meanwhile, a calibrated spectral radiometer was used to measure the spectral radiance to check the results above at the ground level. Experiments have been done in Kunming. Choosing middle altitude summer atmospheric and land aerosol type, the relative error between calculation and measurement is below 3.3% in the spectral range of 0.50 to 0.68 μm. Changing atmospheric model only, the relative error can be up to 10%, whi
