3The plant canopy model has been extended to the prognostic equation for   
4the potential temperature and the prognostic equation for the concentration
5of a passive scalar, as proposed by Watanabe (2004) and Shaw and Schumann
6(1992). (prognostic_equations, plant_canopy_model)

8Within a job chain, the number of processors or the virtual processor grid
9is now allowed to be changed. This modifies the domain decomposition and
10requires that the PEs within a restart job have to know from which file(s) they
11have to read their restart data (up to now there is a one to one relation
12between the restart files and the PEs, i.e. processor 4 only reads data
13from file "_0004"). Informations about the subdomain index limits of all
14restart files are now written by PE0 (to file "_0000"). Also, all variables
15containing global values which do not depend on the subdomain are written
16to file "_0000" only. In a restart run, this file is opened by all PEs to
17read these global values and the informations about the subdomain index
18limits. Depending on these index limit information it is decided which
19restart file(s) has/have to be opened in order to read the complete data
20necessary for the current subdomain.
21
22The turbulence recycling method of Kataoka and Mizuno (2002) has been
23implemented. A pre-run with smaller model domain can be used to initialize
24the real run, in order to spare the CPU time needed to get the turbulence
25into a quasi-stationary state (see initializing_actions =
26'read_data_for_recycling').
27
28Particle advection adjusted for ocean runs.
29
30User-defined spectra.
31
32Argument -c introduced to most of the subjob calls, which allows the user to
33choose his own job catalog by setting job_catalog in the configuration file
34(default is ~/job_queue). Workaround for mpixec with -env option.
35Adjustments for lcxt4 (Bergen Center for Computational Science) (mrun, subjob)

42Changed:
43-------
44Modification of the integrated version of the profile function for momentum
45for unstable stratification; more consistent flux definitions. (wall_fluxes,
46production_e)
47
48Strict grid matching along z is not needed for mg-solver. (check_parameters)
49
50Sharp lateral edges of the plant canopy introduced. Before smaller
51values of the leaf area density than those applied in the prognostic
52equation for the vertical velocity were used in the prognostic equations
53for u and v at the boundaries of the plant_canopy. (init_3d_model) 
54
55-cross_ts_* (read_var_list, write_var_list)
56-dopr_time_count, old profil parameters (cross_..., dopr_crossindex,
57 profile_***) removed (read_3d_binary, write_3d_binary)
58
59hom_sum moved, volume_flow_area, volume_flow_initial moved from ..._3d_binary
60to ..._var_list, hom_sum is now allocated in parin instead of init_3d_model
61
62npex, npey moved from inipar- to d3par-namelist (parin)
63
64myid_char14 removed. This was used since on IBM machines the process rank may
65be changed when the final communicator is defined, in order to save the
66preliminary processor-id for opening the binary output file for restarts
67(unit 14), because otherwise a mismatch occured when reading this file in a
68restart job. This mechanism is not needed any more since the subdomain
69informations are now contained in file _0000. (parin, check_open)
70
71Transpositions for the 2D domain decomposition have been optimized by using
72f_inv as an automatic array instead of providing the memory by a dummy argument.
73This spares one copy loop per transposition. Order of indices in the 3D loops
74in some of the transpose routines have been rearranged for better cache utilization.
75Both have been suggested by Roland Richter (SGI) as part of the
76HLRN-II benchmark process. (transpose)
77
78Workaround for getting information about the coupling mode. (palm)
79
80Format adjustments in order to allow CPU# > 999. (cpu_statistics)
81
82Provisional solution for run_control_1d output: add 'CALL check_open( 15 )'
83(init_1d_model)
84
85advec_s_ups, advec_u_ups, advec_v_ups, advec_w_ups, calc_spectra, check_open, check_parameters, cpu_statistics, init_1d_model, init_3d_model, modules, palm, parin, poisfft, production_e, read_var_list, read_3d_binary, transpose, wall_fluxes, write_var_list, write_3d_binary

88Errors:
89------
90Bugfix: change definition of us_wall from 1D to 2D. Tests showed that this decreases
91u* by some 10% and increases TKE and momentum fluxes by some 10% because friction
92was underestimated and momentum fluxes were wrongly calculated due to the bug.
93(prandtl_fluxes, wall_fluxes)
94
95Bugfix: calculation of horizontal fluxes at vertical walls (diffusion_s)
96
97Bugfix: zero assignments to tendency arrays in case of restarts (init_3d_model)
98
99Bugfix: wrong grid level used in multigrid solver, routine restrict (poismg)
100
101Bugfix: Construction of vertical profiles when 10 gradients have been
102specified in the parameter list (ug, vg, pt, q, sa, lad). (check_parameters)
103
104Bugfix: Determination of the number of vertical levels for which spectra
105shall be output - 100 replaced by 10. (netcdf)
106
107Bugfix: Lengths of those characters that are needed for the output of the
108characteristic levels of potential temperature, the geostrophic wind,
109scalar concentration, humidity and leaf area density to the header file
110has been increased. (header)
111
112Bugfix: add ')' in user_read_restart_data.
113
114The leaf area density is explicitly set to its surface value at k=0. (check_parameters)
115
116Introduce prefix_chr to ensure unique dvrp_file path.
117
118small bugfixes for user_interface sample code (comments):
119- initialize ustvst with 0.0 as it is now computed only until nxr and nyn
120- two ALLOCATE statements moved from user_read_restart_data back to user_init
121- remove 'READ (13) u2_av' statement in user_read_restart_data
122
123Bugfix: remove IF statement in plant_canopy_model_ij (plant_canopy_model)
124
125Bugfix: divide sums(k,8) (e) and sums(k,34) (e*) by ngp_2dh_s_inner(k,sr)
126(like other scalars) (flow_statistics)
127
128Bugfix: dopr_time_count was written on the binary file, which caused that
129NetCDF files newly created by restart files (no append of existing files!)
130contained uneccessary time levels. (read_3d_binary, write_3d_binary)
131
132Bugfix: extra '*' removed in user_statistics sample code (user_interface)
133
134Bugfix: a stop command was missing in some cases of the parallel branch (local_stop)
135
136Bugfix in volume flow control for non-cyclic boundary conditions (pres)
137
138Bugfix: misplaced #endif directives (combine_plot_fields)
139
140check_parameters, diffusion_s, flow_statistics, init_dvrp, init_3d_model, local_stop, plant_canopy_model, poismg, prandtl_fluxes, pres, read_3d_binary, user_interface, wall_fluxes, write_3d_binary
