Code figure
0 0 to 50 m
1 50 to 100 m
2 100 to 200 m
3 200 to 300 m
4 300 to 600 m
5 600 to 1000 m
6 1000 to 1500 m
7 1500 to 2000 m
8 2000 to 2500 m
9 2500m or more, or no clouds
/ Height of base of cloud not known or base of clouds at a level lower and tops at a level higher than that of the station
Notes:
  1. A height exactly equal to one of the values at the ends of the ranges shall be coded in the higher range, e.g. a height of 600 m shall be reported by code figure 5.
  2. Due to the limitation in range of the cloud-sensing equipment used by an automatic station, the code figures reported for h could have one of the three following meanings:
    1. The actual height of the base of the cloud is within the range indicated by the code figure; or
    2. The height of the base of the cloud is greater than the range indicated by the code figure but cannot be determined due to instrumental limitations; or
    3. There are no clouds vertically above the station.
