Alternative Approach for Satellite Cloud Classification: Edge Gradient Application
Figure 6
Comparative histograms for January 1, 2006, of the cloud type frequency obtained from the cloud top temperature (CTT) gradient classification a, b and the ISCCP classification method (a) the matching rate for each cloud type (b) and each region (c). 1—Ci: cirrus, 2—Cs: cirrostratus, 3—Dc: deep convection, 4—Ac: altocumulus, 5—As: altostratus, 6—Ns: nimbostratus, 7—Cu: cumulus, 8—Sc: stratocumulus, and 9—St: stratus. All: all areas.
