    """Input format.
    
    Parameters
    ----------
    meteo_files: `bool`, optional
        Switch the text file format of the meteo input data. If true, a given
        meteorological input data (e.g. rainfall) is separated into multiple
        data text files. If false, the data are in the same CSV file. Default
        is False.

    starting_date: `datetime.datetime`, optional
        Starting date of the input data text files. Only used if the text files
        do not provide dates in the first column. This parameter sets the date
        of the first data record (first row of the file). Default is 1900-01-01.

    time_step: `datetime.timedelta`, optional
        Frequency of the input data text files. Only used if the text files do
        not provide dates in the first column. Associated to the `starting_date`
        parameter, it allows to set the dates of all the rows of the input
        files. Default is one day.
    
    Returns
