Determination of Effective Absorption Property of Atmospheric Aerosols and Validity of that Value in Calculating the Flux Divergence. Part II: Application

[摘要] Effective absorption properties of atmospheric aerosols were estimated from five aircraft measurements of reflectance using a method described in our previous paper. Results indicate that the imaginary terms of the effective refractive indices vary within the range from 0 to 0.013 showing a tendency to increase in lower layer corresponding to an increase in industrial aerosols. The method is based on Mie theory and this may introduce additional uncertainties since shapes of real atmospheric particles are nat spherical in general. Determination of this effect on reflectance is vey difficult. But observed and calculated radiative flux divergences in the atmosphere are compared for rough investigation of above uncertainties. The results of the comparisons indicate that they are in good agreement.
