+turbulence recycling method of Kataoka and Mizuno (2002) has been
+implemented. A precursor run must be used to initialize the main run
+with a quasi-stationary turbulence state (see <span style="font-family: monospace;">initializing_actions</span> = <span style="font-style: italic;">'read_data_for_recycling'</span>).
+The precursor run may have a smaller domain than the main run, which
+helps to spare CPU time. New parameters for steering the recycling
+method are <span style="font-family: monospace;">turbulent_inflow</span>, <span style="font-family: monospace;">recycling_width</span>, <span style="font-family: monospace;">inflow_damping_height</span>, and <span style="font-family: monospace;">inflow_damping_width</span>.<br><br>One
+new feature related with the recycling method is that within a job
+chain, the number of processors or the virtual processor grid is now
+allowed to&nbsp;change. Such a change modifies the domain decomposition
+and requires that the PEs within a restart job have to know from which
+file(s) they have to read their restart data (up to now there has been
+a one to one relation between the restart files and the PEs, i.e.
+processor 4 only reads data from file "_0004"). Informations about the
+subdomain index limits of all restart files are now written by PE0 (to
+file "_0000"). Also, all variables containing global values which do
+not depend on the subdomain are written to file "_0000" only. In a
+restart run, this file is opened by all PEs to read these global values
+and the informations about the subdomain index limits. Depending on
+these index limit information it is decided which restart file(s)
+has/have to be opened in order to read the complete data necessary for
+the current subdomain.<br><br>The plant canopy model has been extended
+to the prognostic equation for&nbsp;the potential temperature
+and&nbsp;passive scalar, as proposed by Watanabe (2004) and Shaw and
+Schumann (1992).<br><br>Particle advection adjusted for ocean runs.<br><br>Grid

+modification of the calculation of the vertical turbulent momentum
+fluxes u'w' and v'w'; the first usws that is computed corresponds to
+-u'w'/u* and not as priorily assumed to (-u'w')**0.5, the first vsws
+that is computed corresponds to -v'w'/u* and not as priorily assumed to
+(-v'w')**0.5. Therefore, the intermediate result for usws has to be
+multiplied by -u* instead by itself in order to get u'w'. Accordingly,
+the intermediate result for vsws has to be multiplied by -u* instead by
+itself in order to get v'w'. As u* is calculated for the position of a
+scalar an additional interpolation of u* to the position of u and v,
+respectively, is necessary. As u* is not determined for the ghost
+points on each PE, an additional exchange of information from
+neighbouring PEs is necessary. Tests showed that this
+decreases u* by some 10% and increases TKE and momentum fluxes by some
+10% because friction was underestimated and momentum fluxes were
