Improved coupler: evaporation - salinity-flux coupling for humidity = .T.,

avoid MPI hangs when coupled runs terminate, add DOC/app/chapter_3.8;

Optional calculation of km and kh from initial TKE e_init;
Default initialization of km,kh = 0.00001 for ocean = .T.;
Allow data_output_pr= q, wq, w"q", w*q* for humidity = .T.;
Bugfix: Rayleigh damping for ocean fixed.

	27
[61]	28	<p style="line-height: 100%;">Starting from version 2.1
	29	PALM includes
[5]	30	so-called software packages which can be used optionally. These
	31	software packages are part of the model, but they are not compiled with
	32	the default model
	33	installation (actually, the routines of the corresponding packages are
	34	compiled within the installation, but these subroutines are empty,
	35	i.e. they do not contain any executable statements). Thus the
	36	compilation time as well as the memory demand of the model is limited
	37	to the real needs. </p>
[108]	38
[61]	39	<p style="line-height: 100%;">To use software packages in
	40	a model run,
	41	they must be requested with <b>mrun</b> option <tt><font style="font-size: 10pt;" size="2">-p</font>.</tt>
[5]	42	Then the subroutines belonging to the respective package are
	43	additionally compiled for the run (and the respective restart
	44	runs; the filenames of these subroutines are also displayed on the
[61]	45	terminal after <b>mrun</b> has been called). If one wants
	46	to use e.g.
[5]	47	the two packages with the names
[61]	48	<tt>package1</tt> and <tt>package2</tt>, then
	49	the <b>mrun</b> call
[5]	50	has to be: </p>
[108]	51
	52	<ul>
	53
	54	<p style="line-height: 100%;"><tt><font style="font-size: 10pt;" size="2">mrun ... -p
[61]	55	“package1 package2” </font>.</tt></p>
[108]	56
	57	</ul>
	58	<p style="line-height: 100%;">Starting from version 3.2, the particles-package is part of the default model, so it does not have to be switched on using <span style="font-weight: bold;">mrun</span>-option <span style="font-family: Courier New,Courier,monospace;">-p</span>. However, the respective parameters have still to be set by using the NAMELIST group <span style="font-family: Courier New,Courier,monospace;">particles_par</span>.</p>
	59	<p style="line-height: 100%;">Further package
[61]	60	names can be added to
[5]	61	the list, separated by blanks. If the respective packages permit user
	62	steering, the appropriate parameters must be given at the end of
	63	the file <a href="chapter_3.4.html#PARIN">PARIN</a>.
[61]	64	They must be given <b>before</b> possible user-defined
	65	parameters!
[5]	66	Each package requires its own NAMELIST group. The respective NAMELIST
	67	group name is given in the table below. For the example above one
	68	would have to add the following lines to PARIN (example):   </p>
[108]	69
	70	<ul>

	72	<p style="line-height: 100%;"><tt><font style="font-size: 10pt;" size="2">&namelist_packagename1

	74	“abcd” /</font></tt><font style="font-size: 10pt;" size="2"> </font> </p>
[108]	75
	76	<p style="line-height: 100%;"><tt><font style="font-size: 10pt;" size="2">&namelist_packagename2
[61]	77	var3 = .TRUE.,
