Changes due to new module structure of the plant canopy model: 23 ! module plant_canopy_model_mod now contains a subroutine for the 24 ! initialization of the canopy model (init_plant_canopy), 25 ! limitation of the canopy drag (previously accounted for by calculation of 26 ! a limiting canopy timestep for the determination of the maximum LES timestep 27 ! in subroutine timestep) is now realized by the calculation of pre-tendencies 28 ! and preliminary velocities in subroutine plant_canopy_model, 29 ! some redundant MPI communication removed in subroutine init_plant_canopy 30 ! (was previously in init_3d_model), 31 ! unnecessary 3d-arrays lad_u, lad_v, lad_w removed - lad information on the 32 ! respective grid is now provided only by lad_s (e.g. in the calculation of 33 ! the tendency terms or of cum_lai_hf), 34 ! drag_coefficient, lai, leaf_surface_concentration, 35 ! scalar_exchange_coefficient, sec and sls renamed to canopy_drag_coeff, 36 ! cum_lai_hf, leaf_surface_conc, leaf_scalar_exch_coeff, lsec and lsc, 37 ! respectively, 38 ! unnecessary 3d-arrays cdc, lsc and lsec now defined as single-value constants, 39 !
