    838838The file contains column-separated profiles of the prognostic variable u, v, w, lpt, q originating from measurements or larger scale models which are to be used for nudging. Additionally, height information and the nudging time scale tnudge have to be provided.\\\\
    839 In case of  [../inipar#nudging nudging] = ''.T.'' the subroutine [source:palm/trunk/SOURCE/nudging.f90 init_nudge] which is called in  [source:palm/trunk/SOURCE/palm.f90 palm] reads the profile information in a free floating point format. The hash character (#) is used as a special steering character. The data in the file has to be organized in the following way:\\
     839In case of  [../inipar#nudging nudging] = ''.T.'' the subroutine {{{nudge_init}}} in [source:palm/trunk/SOURCE/large_scale_forcing_nudging_mod.f90 large_scale_forcing_nudging_mod] which is called in [source:palm/trunk/SOURCE/module_interface.f90 module_interface_init] reads the profile information in a free floating point format. The hash character (#) is used as a special steering character. The data in the file has to be organized in the following way:\\
    840840* The file can begin with an arbitrary number of lines beginning with a # where for example header information can be stored.
    841841* A line beginning with ''# time'' indicates the beginning of a profile data set at time step ''time''.
     
    843843A sketch of the layout of [[attachment:NUDGING_DATA|NUDGING_DATA]] is attached.\\
    844844\\
    845 The height information does not have to match PALM's grid. A linear, vertical interpolation to the zu-grid of PALM is conducted in [source:palm/trunk/SOURCE/nudging.f90 init_nudge]. A linear, temporal interpolation of the profile data is conducted in the subroutine [source:palm/trunk/SOURCE/nudging.f90 nudge].\\\\
     845The height information does not have to match PALM's grid. A linear, vertical interpolation to the zu-grid of PALM is conducted in {{{nudge_init}}}. A linear, temporal interpolation of the profile data is conducted in the subroutine {{{nudge}}}.\\\\
    846846An example parameter file (p3d) with nudging can be found [../examples/lsf here].
