[1484]35! Changes in the course of the canopy-model modularization:
36!   module plant_canopy_model_mod added,
37!   definition of array cdc (canopy drag coefficient) removed, since it is now
38!   defined purely as a single constant value (see module plant_canopy_model)
[1354]39!
40! 1353 2014-04-08 15:21:23Z heinze
41! REAL constants provided with KIND-attribute
42!

[1320]44! kind-parameters added to all INTEGER and REAL declaration statements,
45! kinds are defined in new module kinds,
46! old module precision_kind is removed,
47! revision history before 2012 removed,
48! comment fields (!:) to be used for variable explanations added to
49! all variable declaration statements
[211]50!
[1037]51! 1036 2012-10-22 13:43:42Z raasch
52! code put under GPL (PALM 3.9)
