Alternative Approach for Satellite Cloud Classification: Edge Gradient Application
Figure 5
Cloud type classification using the thermal image segmentation method based on cloud top temperature (CTT) gradient classification (a) compared to the cloud type classification using the ISCCP classification method (b) for spring and end of summer (April 2 and September 3, 2006, resp.). 1: cirrus, 2: cirrostratus, 3: deep convection, 4: altocumulus, 5: altostratus, 6: nimbostratus, 7: cumulus, 8: strato-cumulus, and 9: stratus.
