卷云中粒子的密度变化对可见光波段能量传输的影响

Cirrus Cloud Ice Particle Density Variation Effect on the Visible Radiation Transfer

本文讨论了卷云冰晶粒子的密度随其尺度大小的变化。及其对折射指数的影响。对该变化所导致的粒子的光散射参数的变化进行了计算。采用ＭｏｎｔｅＣａｒｌｏ模式，根据观测到的冰晶粒子的数密度，使用不同的粒子密度分布，计算了卷云对０５５μｍ波长的入射光的反射和透射率。结果表明，不同的粒子密度假设会导致一定的差别，但卷云中粒子的密度变化对可见光波段能量传输的影响非常小，可忽略不计。

The ice particle density variation with the particle size and its effect on the ice particle refractive index were investigated The variations in the scattering parameter caused by ice particle density variations were calculated Based on the measured ice particle number concentration and different ice particle density assumptions, the reflection and refraction ratio of cirrus cloud for the wavelength 0 55 μm have been calculated using a Monte Carlo model The results show that the effect of ice particle density variation in cirrus clouds on the visible radiative tranfer is very small and can be neglected
