Fig. 2From: Theoretical basis of the algorithms and early phase results of the GCOM-C (Shikisai) SGLI cloud productsDetermining the CCL in the cloud discrimination process. The horizontal axis represents the values for the threshold test. In this case, the observed value is large when clouds are present. Two threshold values, the lower limit and upper limit, are set, creating an ambiguous area between the two limits that is expressed as a CCL from 0 to 1Back to article page
