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

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

9visualization<br>
10</h3><p style="line-height: 100%;">PALM is able to
11output
12data of different quantities as time series,
13vertical profiles (usually horizontally averaged), two-dimensional
14cross sections or <font color="#000000">3d-volume data.</font>
15Depending on the kind of output (time series, profiles, etc.) and the
16output format (ASCII&nbsp; or binary) data are written
17to different files (file descriptions can be found in
18<a href="../app/chapter_3.4.html">chapter
193.4</a>). By default, all data
20output files are in NetCDF format (link to the NetCDF documentations in
21the Internet and on the PALM homepage), which can be processed by many
22public domain and commercial (graphic) software. Data from NetCDF files
23can also be easily read from FORTRAN programs provided that a NetCDF
24library is available. More detailed informations about the
25PALM-NetCDF-output is given in the next subchapter (<a href="../app/chapter_4.5.1.html">4.5.1</a>).</p>
26<p style="line-height: 100%;">Due to historical reasons,
27PALM can also
28output data in other formats suitable for some special graphic
29software. The exact format of these files corresponds to the
30requirements of the respective software. Still available at IMUK are <a href="http://www.muk.uni-hannover.de/institut/software/profil_beschreibung.html">profil</a>
31(time series, profiles), <a href="http://www.muk.uni-hannover.de/institut/software/iso2d_beschreibung.html">iso2d</a>
32(2d cross sections) and <b>AVS</b> (e.g. iso-surfaces of
333d volume
34data). The special files created by PALM can be directly used
35as input files for these plot programs. Beyond that, <b>profil</b>
36and
37<b>iso2d</b> need additional information
38about the plot layout (e.g. titles, axes labels, arrangement of the
39coordinate systems, etc.) provided by so-called parameter files<font color="#800000">.
40</font><font color="#000000">Thes</font>e
41files are also created by
42the PALM, providing a default layout (e.g. plots produced by <b>iso2d</b>
43show. only isolines and no color shading). Within certain
44limits the plot layout can be steered by some PALM parameters.
45Beyond that the user can edit the parameter files created by PALM and
46change, supplement or remove the given default values
47according to his needs. Beside the file with the (binary) data to be
48visualized, <b>AVS</b> additionally needs a file with
49coordinate information (likewise binary) and an ASCII file in the
50so-called FLD format, which describes the structure of the two binary
51files. Coordinate and FLD file are also created by the PALM. However,
52with <b>AVS</b> (differently than with <b>profile</b>
53or <b>iso2d</b>)
54the plot layout must always be additionally designed by the user
55with the help of the AVS network editor. &nbsp;</p>
56<p style="line-height: 100%;">In the following
57subchapters, steering
58of the different data output and how to create plots of the data is
59described by some examples. Not all details of steering
60are mentioned. If necessary, these can be found within the
61description of the respective parameters.<br>
