The Research of Parameterization Method of Determining the Aerosol Optical Absorption Characteristics
确定气溶胶吸收光学特性的参数化方法研究

In this paper, the aerosol data and radiative data of Lanzhou and Beijing are used. The diurnal variations of imaginary part are determined by using radiative observational data and radiative model for the clean sky according to parameterization method of the ratio of the aerosol absorption and back scattering which was proposed by Robinson. Compared with the values calculated from the element carbon content of the East Asia atmospheric monitoring net they are in good agreement. The diurnal variation of imaginary part is that after sunrise the imaginary part is the largest and it reaches the minimum in the afternoon and after sunset it increases again.
