The two algorithms both have a global score around 80 % . the validation result indicates that the clear failure score is relative higher than the cloud failure score . this implies that the two algorithms tested in this research are more strict for clear pixel diagnosis than for cloud 这两种方法在我国东部及其以东的海面上的正确率在80左右，晴空误判率较高，云的误判率相对低，即表观反射率法和双通道动态阈值法对晴空区的判定比较严格。
