! !MODULE:      USER_OUTPUT_GENERAL
!
! !DESCRIPTION: 
! 
!   This module provides objects and methods for the AEROCOM-2 related 
!   diagnostics package. It is strongly related to the setup of the 
!   optics module. 
!   A list of parameters are defined for which daily averages are output 
!   (so far), result is one file per day containing 50 2d-fields and 
!   4 3d-fields. 
! 
!   Life cycle(s): 
!   1) output_aerocom_init: 
!      - if( newsrun ): - allocation and initialisation of output container
!                         (mixf%..., drydepos/wetdepos/emission, wdep_out)
!                       - initialisation of optics module
!                          - lookuptable
!                          - wavelengths
!      - open output file (for today), initialise it and write attributes
!   2) output_aerocom_step:
!      - gather tracer
!      - add current state of model to containers 
!        (weighted by time since last call, --> period of validity)
!         - do fluxes, surface concentrations and loads
!         - do optics
!             - aerocom_aopio_init: initialise and fill input parameters       
!             - optics::optics_calculate_aop: 
!                 calculate optical properties (per wavelength)
!                 (take into account additional splitting, facilitated in 
!                  optics::optics_calculate_aop) 
!             - fill containers for optical properties
!             - free optics input parameters
!             - fill aerocom output containers 
!   3) output_aerocom_write: 
!      - collect_budgets: 
!         - use current budget containers (budemi, buddep, buddry)
!         - compare with saved values and infer by that the increment
!         - add to temporary output containers (wetdepos,drydepos,emission)
!      - write output containers to file 
!      - close file 
!   4) output_aerocom_done: 
!      - free allocated containers 
!        (mixf%..., drydepos/wetdepos/emission, wdep_out)

    ! 1) according to the parallelisation there is different container sizes for 
    !    the results of the optics; these have to be allocated correctly 
    !    (aop_output_ext/a/g/add) 
    ! 2) the optics code is called (init/calculate_aop/done), see documentation
    !    in the optics module
    ! 3) the distributed fields (levels/tracers) are reshaped to global fields 
    !    (opt_ext/a/g/add), according to parallelisation 
    ! 4) fields are communicated such that the result contains the right 
    !    total extinctions, albedos, asymmetry factors etc. 
    ! 5) post-calculations (AOD etc.) are done and results are written
    !    to mixf%../statf% containers as well as to the AOD dump files
    ! 6) done...
