 Before carrying out a model run, the user has to determine the model parameters. These data are assigned with the help of so-called "''namelist-driven input''" (Fortran - namelist– input). The chosen values of the model parameters are written into an ASCII file with fixed format, which is expected by the model as an input file under the local name PARIN. On this file the parameters are represented by their variable names they have in the model. These parameters can be assigned one or more values, depending on the type and size the variable has. The following example shows the format of the file [../iofiles#PARIN PARIN]:\\\\
