+File contains column-separted profiles of the prognostic variable u, v, w, pt, 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.\\\\
 In case of  [../inipar#nudging nudging] = ''.T.'' the subroutine {{{init_nudge}}} which is called in {{{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:\\
-* the file can begin with an arbitrary number of lines beginning with a # where header information can be placed
-* a line beginning with ''# time'' indicates that a profile data set at time step ''time'' follows afterwards
-* profile data following ''# time'' is column separated and has to be in the following sequence: height information z, nudging time scale tnudge, prognostic variables u, v, w, pt, q
-The height information does not have to match PALM's grid. A vertical interpolation to the zu-grid of PALM is conducted in {{{init_nudge}}}.
+* the file can begin with an arbitrary number of lines beginning with a # where for example header information can be stored
+* a line beginning with ''# time'' indicates the beginning of a profile data set at time step ''time''
+* profile data following ''# time'' has to be column separated and in the following sequence: height information z, nudging time scale tnudge, prognostic variables u, v, w, pt, q\\
