-Multiple quantities can be assigned, e.g. '''data_output''' = '' 'e', 'u', 'w' ''.
+Multiple quantities can be assigned, e.g. '''data_output''' = '' 'e', 'u', 'w' ''.\\\\
+By assigning the pure strings from the above table, 3d volume data is output. Cross section data can be output by appending the string '_xy', '_xz', or '_yz' to the respective quantities. Time averaged output is created by appending the string '_av' (for cross section data, this string must be appended after the cross section string). Cross section data can also be (additionally) averaged along the direction normal to the respective section (see below). Assignments of quantities can be given in arbitrary order:\\\\
+Example:\\\\
+'''data_output''' = '' 'u', 'pt_xz_av', 'w_xy', 'u_av' ''.\\\\
+This example will create the following output: instantaneous 3d volume data of u-velocity component (by default on file [[DATA_3D_NETCDF]]), temporally averaged 3d volume data of u-velocity component (by default on file [[DATA_3D_AV_NETCDF]]), instantaneous horizontal cross section data of w-velocity component (by default on file [[DATA_2D_XY_NETCDF]]), and temporally averaged vertical cross section data of potential temperature (by default on file [[DATA_2D_XZ_AV_NETCDF]]).\\\\
+The user is allowed to extend the above list of quantities by defining his own output quantities (see the user-parameter [[../userpar#data_output_user|data_output_user]]).\\\\
