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'.
