apparent reflectance meaning in English

表观反射比

This paper presents two methods for cloud detection : multi - channel dynamical threshold algorithm and apparent reflectance algorithm
本文介绍了两种云检测算法：双通道动态阈值法和表观反射率法。
The apparent reflectance algorithm estimates the clear - sky visible apparent reflectance as the bases of visible channel thresholds with the 6s radiation transfer model . cloud detection is tested with apparent reflectance algorithm to gms5 images
将表观反射率乘以不同的系数得阈值，待检测云图的表观反射率大于阈值的像元为云像元。
The validation result also indicates that over land , the apparent reflectance algorithm behaves better than dynamical threshold algorithm ; while over ocean , the clear and cloud failure scores do not have much difference
本文的研究工作表明，当不用历史资料，不知道区域先验气候值和辐射值时，双通道动态阈值法和表观反射率法均有可能获得合理的结果。
