User defined quantities for which horizontally averaged profile data is to be output. \\\\
Beside the PALM standard output quantities (which can be selected via parameter [../d3par#data_output_pr data_output_pr]), the user can define (without any restriction) additional 
output quantities (e.g. turbulent resolved-scale horizontal momentum fluxes, etc.). Each of these quantities has to be given a unique identifier (string) which must be different 
from the strings defining the standard output quantities (see list from the description of [../d3par#data_output_pr data_output_pr]). Data output can be switched on by assigning the 
respective strings to '''data_output_user'''.\\\\
The user has to calculate/provide the respective data array(s) by appropriately extending the user interface (see [[../userinterface]])\\\\

{{{#!td
User defined quantities for which 2d cross section and/or 3d volume data are to be output.\\\\
Beside the PALM standard output quantities (which can be selected via parameter [../d3par#data_output data_output]), the user can define (without any restriction) additional output 
quantities (e.g. the temperature variance, etc.). Each of these quantities has to be given a unique identifier (string) which must be different from the strings defining the standard 
output quantities (see list from the description of [../d3par#data_output data_output]). Data output can be switched on by assigning the respective strings to '''data_output_user'''. \\\\
The user has to calculate/provide the respective data array(s) by appropriately extending the user interface (see [[../userinterface]])\\\\
For further steering of the user defined output (output times, cross section levels, time averaging, etc.), the steering parameters for [../d3par#data_output data_output] apply 
accordingly.\\\\
'''Example:'''\\
If the user defined output quantity is the temperature variance and if the user has chosen the string '' 'pt2' '' as an identifier for this quantity, then output of horizontal cross sections can be selected by assigning '''data_output_user''' = '' 'pt2_xy' ''.
