 Now the run parameters ([../../d3par &d3par] ) must be specified. To produce a quasi stationary boundary layer the simulated time should be at least one hour, i.e. [../../d3par#end_time end_time]'' = 3600 s.'' To stimulate convection, the initially homogeneous (zero) wind field must be disturbed ([../../d3par#create_disturbances create_disturbances]'' = .T.''). These perturbations should be repeated in a temporal interval of [../../d3par#dt_disturb dt_disturb]'' = 150.0 s'' until the energy of the perturbations exceeds the value [../../d3par#disturbance_energy_limit disturbance_energy_limit]'' = 0.01 m^2^/s^2^''. After each time step run time informations (e.g. size of the timestep, maximum velocities, etc.) are to be written to the local file [../../iofiles#RUN_CONTROL #RUN_CONTROL] ([../../d3par#dt_run_control dt_run_control]'' = 0.0 s'').
 
-Instantaneous cross section data of vertical velocity (w) and potential temperature (pt) are to be output for horizontal (xy) and vertical (xz) cross sections, and additionally, time averaged (av) vertical cross section data are to be output for the vertical velocity: data_output = 'w_xy', 'w_xz', 'w_xz_av', 'pt_xy', 'pt_xz'. Output of instantaneous (time averaged) data is done after each 900 (1800)s: dt_data_output = 900.0, dt_data_output_av = 1800.0. The averaged data are time averaged over the last 900.0 s, where the temporal interval of data entering the average is 10 s: averaging_interval = 900.0, dt_averaging_input = 10.0. Horizontal cross sections are output for vertical levels with grid index k=2 and k=10, vertical cross sections are output for index j=20: section_xy = 2, 10, section_xz = 20. For runs on more than one processor, cross section data are collected and output on PE0: data_output_2d_on_each_pe = .F..

 Output of vertical profiles is to be done after each 900 s. The profiles shall be temporally averaged over the last 600 seconds, whereby the temporal interval of the profiles entering the average has to be 10 s: dt_dopr = 900.0 s, averaging_interval_pr = 600.0 s, dt_averaging_input_pr = 10.0 s. The temperature profile including the initial temperature profile (therefore '#pt'), the subgrid scale, resolved and total vertical sensible heat flux as well as the variances of the vertical velocity and the potential temperature are to be output:  data_output_pr = '#pt', 'w"pt”', 'w*pt*', 'wpt', 'w*2', 'pt*2'.
