44! Changes in the course of the canopy-model modularization:
45!   module plant_canopy_model_mod added,
46!   definition of array cdc (canopy drag coefficient) removed, since it is now
47!   defined purely as a single constant value (see module plant_canopy_model)
48!
49! 1353 2014-04-08 15:21:23Z heinze
50! REAL constants provided with KIND-attribute
51!
52! 1320 2014-03-20 08:40:49Z raasch
53! kind-parameters added to all INTEGER and REAL declaration statements,
54! kinds are defined in new module kinds,
55! old module precision_kind is removed,
56! revision history before 2012 removed,
57! comment fields (!:) to be used for variable explanations added to
58! all variable declaration statements
59!
60! 1036 2012-10-22 13:43:42Z raasch
61! code put under GPL (PALM 3.9)

68!> Initialisation of the leaf area density array (for scalar grid points) and
69!> the array of the canopy drag coefficient, if the user has not chosen any
70!> of the default cases
