摘要

摘要: 在辐射传输模式CRM中引入粒径为0.5、1.0、2.0、4.0、8.0 m的5段矿尘气溶胶粒子,模拟计算气溶胶对短波辐射通量的影响。计算结果表明:气溶胶引起晴空短波净辐射通量减少;在分布有气溶胶的层内,粒子半径增大、光学厚度增大都会使短波净辐射通量减少;在气溶胶层以上,辐射通量的变化与具体的粒子半径有关。

Abstract: A radiation transfer model(CRM) coupled with the dust aerosol which was divided into five intervals (r = 0.5, 1.0, 2.0, 4.0, 8.0 m) was used to simulate the clear sky short-wave fluxes in order to analyse the radiative effects of dust aerosol. The results showed that the dust aerosol can bring about the reduction of the short-wave fluxes in aerosol layer; the reduction of the short wave fluxes increased with the increasing of optical depth and radius of dust aerosol. But the variation of the short wave fluxes above the aerosol layer was different from the variation in the aerosol layer, which was related with the radius and optical parameters of the dust aerosol.
