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

104!--       in order to minimize communication between CPUs.
