v7 v8 29 29 * '''multiple_parameters:''' Binary flag (0;No , 1: Yes) indicating whether the experiment is based on independent realizations with different values on the WRF-namelist.input file. When activated it has to be accompanied with appropriated values of: 30 30 * multiparams_variables: The set of parameters that we want to change (some of them or all) between realizations. It is given as a coma-separated WRF-namelist.input files (no record specification is necessary if the parameter already appears on the provided WRF-version [wiki:Developers#nameslit.input_template namelist.input template], If not it should be {{{[parameter]__[record]}}}) 31 * multiparams_combinations: Values of the 31 * multiparams_combinations: Values of the changing parameters for each realization. Parameters should be separated by commas and realizations are separated by '{{{/}}}'. 32 32 * multiparams_nitems: number of values that should have the namelist parameter. {{{${max_dom}}}}, as many values as domains; {{{1}}}, a single value. 33 33 * multiparams_labels: the output of the experiment is organized with a folder for each realization. Pattern of the folder name for a given realization is {{{[start_date]_[multiparams_combinations]('_' separated)}}}. However, if user provides a set of names ('{{{/}}}' separated) for each realization, folder names will be '{{{[start_date]_[multiparams_labels]}}}' … … 38 38 39 39 == WRF-namelist parameters == 40 User provided namelist values. They will be over-written on {{{multiple_parameters}}} experiments (only the included parameters). User can modify any of the param ters of the namelist. The name must be the same of the {{{namelist.input}}} entry, with a prefix-flag and the record to where belongs.40 User provided namelist values.

Defaults to 6, as suggested by the WRF team for most applications. Under some circumstances (cfl problems) a lower value may be needed. In any case, the time step is adjusted to the higest value lower than {{{timestep_dxfactor}}} times {{{dx}}} fitting evenly in a 1 hour period.46 * '''timestep_dxfactor:''' If present, the time step is computed as dx*'''timestep_dxfactor''', in kilometers.
