 If '''particle_color''' ='' 'pt*' ''and [#color_interval color_interval] = ''-0.5, +0.5'', then all particles at positions with ''pt* <= -0.5 K'' will have a deep blue color and those at positions with ''pt* >= +0.5 K'' will have a deep red color, while those with ''-0.5 < pt* < +0.5'' will vary in color from deep blue to deep red and transition from yellow to blue indicate ''pt* ~ 0.0''.

+Parameter, which allows to bind the displayed particle size to certain flow quantities.\\\\
+The default particle size (diameter) is determined with parameter dvrp_psize.\\\\
+Allowed values for particle_dvrpsize are:
+{{{#!table style="border:none"
+{{{#!td style="vertical-align:top;border:none"
+'absw'
+}}}
+{{{#!td style="vertical-align:top;border:none"
+The particle size depends on the absolute value of the resolved-scale vertical velocity w at the particle position.
+}}}
+}}}
+The particle sizes ranges from 0.25*dx m to 0.85*dx m. The interval of values from the above listed quantities to be mapped to these sizes is defined by parameter dvrpsize_interval.\\\\
+Example:\\
+If particle_dvrpsize = 'absw' and dvrpsize_interval = 1.0, 2.0, then all particles at positions where the absolute value of w is <= 1.0 m/s will have a size of 0.25*dx m and those at positions with |w| >= 2.0 m/s will have a size of 0.85*dx m, while those with 1.0 m/s < |w| < 2.0 m/s will linearly vary in size from 0.25*dx m to 0.85*dx m.
