| 摘 要： | 对由六角形冰晶粒子组成的冰云的１４种冰晶尺度分布，分别用等效球Ｍｉｅ理论和射线光学理论计算了它们在从可见光到近红外谱区的１７个波长上的散射特性参量。并利用由等效球Ｍｉｅ理论获得的散射参数及冰晶尺度分布特征参量ｒｅ（有效半径）建立了冰云光学特性的参数化公式。这些参数化公式的最大相对误差小于５％。

| Abstract: | The scattering properties at 17 wavelengths from visible to near IR spectral region for the 14 kinds of different crystal size distributions of ice cloud which is composed of hexagonal ice crystals are calculated using Mie theory for equivalent surface ice spheres and ray optics,respectively.The parameterization formula of optical properties of ice clouds are estblished by means of scattering parameters obtained from Mie theory for equivalent spheres and characteristic paramter r e (effective radius).Their maximum relative error is less than 5%. |
