| 摘 要： | 介绍了SBDART辐射模式和libRadtran程序包，并利用这两个模式模拟分析了当卷云内冰晶性质如有效半径、冰晶含量以及形状变化时，卷云反照率的变化。模拟分析表明，在相同条件下，不同形状冰晶构成的卷云反照率有所不同，同种冰晶构成的卷云在不同波长的反照率也不同。总的来说，不论是由何种形状冰晶构成的卷云，随着卷云内冰晶含量增大，有效半径减小，卷云反照率增大。这些工作将有助于增进对lib Radtran程序包和卷云性质的了解。

| Abstract: | SBDART radiative model and libRadtran software package are introduced. Cirrus reflectance changes with ice crystal properties are analyzed. These properties include ice effective radius, ice content and ice shape, etc. Simulations show that cirrus reflectance is different when it is made of different ice crystals. In all, the results are that cirrus reflectance increases with increases ice content and decreases ice effective radius for the cloud which consists of any kind of ice crystals. |
