New:
---
ocean version including prognostic equation for salinity and equation of state for seawater. Routine buoyancy can be used with both temperature and density.
+ inipar-parameters bc_sa_t, bottom_salinityflux, ocean, sa_surface, sa_vertical_gradient, sa_vertical_gradient_level, top_salinityflux

advec_s_bc, average_3d_data, boundary_conds, buoyancy, check_parameters, data_output_2d, data_output_3d, diffusion_e, flow_statistics, header, init_grid, init_3d_model, modules, netcdf, parin, production_e, prognostic_equations, read_var_list, sum_up_3d_data, swap_timelevel, time_integration, user_interface, write_var_list, write_3d_binary

New:
eqn_state_seawater, init_ocean

Changed:


inipar-parameter use_pt_reference renamed use_reference

hydro_press renamed hyp, routine calc_mean_pt_profile renamed calc_mean_profile

format adjustments for the ocean version (run_control)

advec_particles, buoyancy, calc_liquid_water_content, check_parameters, diffusion_e, diffusivities, header, init_cloud_physics, modules, production_e, prognostic_equations, run_control

Errors:


Bugfix: height above topography instead of height above level k=0 is used for calculating the mixing length (diffusion_e and diffusivities).

Bugfix: error in boundary condition for TKE removed (advec_s_bc)

advec_s_bc, diffusion_e, prognostic_equations

32! Description:
33! ------------
34! Large-Eddy Simulation (LES) model for the convective boundary layer,
35! optimized for use on parallel machines (implementation realized using the
36! Message Passing Interface (MPI)). The model can also be run on vector machines
37! (less well optimized) and workstations. Versions for the different types of
38! machines are controlled via cpp-directives.
39! Model runs are only feasible using the ksh-script mrun.
