Sentence examples for cloud fraction from inspiring English sources
The temporal evolution of the cloud fraction indicates that the large cloud fraction, with small numerical diffusion, seems to originate from artificial noise.
However, it is difficult to identify the reason for the large cloud fraction being artificial noise.
Figure 12 shows the ice cloud fraction as function of CTT.
The methodology starts with downscaling of the cloud fraction product to 1 km × 1 km cloud cover binary images.
However, the cloud fraction simulated with a small numerical diffusion (i.e., γ ≤ 10−5) was much larger than that of the intercomparison study, and the cloud fraction was completely outside the range of the inter comparison studies.
The simulated experiments indicate that ASTWM removes clouds completely, with a robust overall accuracy (OA) of above 93% under different cloud fractions.
There is exclusively an ice cloud for CTT ≤ –38 °C, exclusively a liquid cloud for CTT ≥ 0 °C, and the ice and liquid cloud fractions vary linearly with CTT between –38 and 0 °C.
Fig. 12 Ice cloud occurrence fraction for ICAS and MODIS C6 SW and TIR algorithms.
These errors were mostly caused by relatively simple estimations of the cloud cover fraction.
Under all sky conditions, the information of clouds is represented by cloud cover fraction (CF) or cloud modification factor (CMF, available only during daytime).
