Cloud classification aids for C_L, C_M and C_H

(Section 2.8.4)

The graphical method of coding represents the same order/priorities to be respected as the described coding instructions (Figure 11, Figure 12 and Figure 13). Start at the top left corner and answer each question until you reach a cartoon of a cloud or a sky view. If this situation corresponds to the reality, then report the code figure on the right-hand bottom of the cartoon. If not, start again at the beginning to find your observed sky, respecting the priorities.
