Notes

1 This example assumes 16 wind speed directions.

2 This example assumes 6 wind speed classes (orange cells). The ranges within the classes can be changed according to the user needs.

3 The number of events for each combination of direction and wind speed class (yellow cells) must be changed according to the user data.

4 The average wind speed for each direction, if available, must be specified within the green cells.

5 Do not write within the white cells.
