     363If data output of time averaged 2d and 3d data is switched on (see [#data_output data_output] and [#section_xy section_xy]), this parameter can be used to assign the temporal interval at which they shall be output. Output can be skipped at the beginning of a simulation using parameter [#skip_time_data_output_av skip_time_data_output_av], which has zero value by default. Reference time is the beginning of the simulation, i.e. output takes place at times t = '''skip_time_data_output_av''' + '''dt_data_output_av''', '''skip_time_data_output_av''' + 2*'''dt_data_output_av''', '''skip_time_data_output_av''' + 3*'''dt_data_output_av''', etc. Since output is only done at the discrete time levels given by the timestep used, the actual output times can slightly deviate from these theoretical values.\\\\
     364The length of the averaging interval is controlled via parameter [#averaging_interval averaging_interval].

     377Temporal interval at which data of vertical profiles shall be output (to local file DATA_1D_PR_NETCDF) (in s).\\\\
     378If output of horizontally averaged vertical profiles is switched on (see [#data_output_pr data_output_pr]), this parameter can be used to assign the temporal interval at which profile data shall be output. Output can be skipped at the beginning of a simulation using parameter [#skip_time_dopr skip_time_dopr], which has zero value by default. Reference time is the beginning of the simulation, thus t = 0, i.e. output takes place at times t = '''skip_time_dopr''' + '''dt_dopr''', '''skip_time_dopr''' + 2*'''dt_dopr''', '''skip_time_dopr''' + 3*'''dt_dopr''', etc. Since profiles can not be calculated for times lying within a time step interval, the output times can deviate from these theoretical values. If a time step ranges from t = 1799.8 to t = 1800.2, then in the example above the output would take place at t = 1800.2. In general, the output always lie between t = 1800.0 and t = 1800.0 + [#dt dt]. If the model uses a variable time step, these deviations from the theoretical output times will of course be different for each output time.\\\\
     379In order to guarantee an output of profile data at the end of a simulation (see [#end_time end_time]) in any way, '''end_time''' should be equal or a little bit larger than the respective theoretical output time. For example, if '''dt_dopr''' = ''900.0'' and ''3600.0'' seconds are to be simulated, then '''end_time''' >= ''3600.0'' should be chosen.\\\\
     380A selection of profiles to be output can be done via parameter [#data_output_pr data_output_pr].

     392{{{#!td
     393Temporal interval at which data of vertical profiles shall be output (output for printouts, local file [[../iofiles#LIST_PROFIL|LIST_PROFIL)]] (in s).\\\\
     394This parameter can be used to assign the temporal interval at which profile data shall be output. Reference time is the beginning of the simulation, thus t = 0. For example if '''dt_dopr_listing''' = ''1800.0'', then output takes place at t = 1800.0, 3600.0, 5400.0, etc. Since profiles can not be calculated for times lying within a time step interval, the output times can deviate from these theoretical values. If a time step ranges from t = 1799.8 to t = 1800.2, then in the example above the output would take place at t = 1800.2. In general, the output always lie between t = 1800.0 and t = 1800.0 + [#dt dt] (numbers are related to the example above). If the model uses a variable time step, these deviations from the theoretical output times will of course be different for each output time.\\\\
     395In order to guarantee an output of profile data at the end of a simulation (see [#end_time end_time]) in any way, end_time should be a little bit larger than the respective theoretical output time. For example, if '''dt_dopr_listing''' = ''900.0'' and ''3600.0'' seconds are to be simulated, then it should be at least '''end_time''' > ''3600.0 + [#dt dt]''. If variable time steps are used (which is the default), '''dt''' should be properly estimated.\\\\
     396Data and output format of the file [[../iofiles#LIST_PROFIL|LIST_PROFIL)]] is internally fixed. In this file the profiles of the most important model variables are arranged in adjacent columns.
