2·Channels composing result shows that the algorithm is effective for underlying surface classification.

通过对选择的通道进行合成，发现此算法用于下垫面分类具有较好的效果。

3·The iterative method is used to calculate sky radiance without the reflectance from underlying surface.

在不考虑下垫面的反射时，利用迭代法来计算天空亮度。

4·The solar radiance diffused by a randomly-rough underlying surface might lead to increase sky radiance.

随机粗糙下垫面对入射到地表的太阳辐射的漫反射必然引起天空亮度的增加。

5·As an important part of underlying surface, cryosphere is in the process of continuous interaction with atmosphere.
