! Description:
! ------------
! 2016/6/9 - Initial version of the USM (Urban Surface Model)
!            authors: Jaroslav Resler, Pavel Krc
!                     (Czech Technical University in Prague and Institute of
!                      Computer Science of the Czech Academy of Sciences, Prague)
!            with contributions: Michal Belda, Nina Benesova, Ondrej Vlcek
!            partly inspired by PALM LSM (B. Maronga)
!            parameterizations of Ra checked with TUF3D (E. S. Krayenhoff)
!> Module for Urban Surface Model (USM)
!> The module includes:
!>    1. radiation model with direct/diffuse radiation, shading, reflections
!>       and integration with plant canopy
!>    2. wall and wall surface model
!>    3. surface layer energy balance
!>    4. anthropogenic heat (only from transportation so far)
!>    5. necessary auxiliary subroutines (reading inputs, writing outputs,
!>       restart simulations, ...)
!> It also make use of standard radiation and integrates it into
!> urban surface model.
!>
!> Further work:
!> -------------
!> 1. Remove global arrays surfouts, surfoutl and only keep track of radiosity
!>    from surfaces that are visible from local surfaces (i.e. there is a SVF
!>    where target is local). To do that, radiosity will be exchanged after each
!>    reflection step using MPI_Alltoall instead of current MPI_Allgather.
!>
!> 2. Temporarily large values of surface heat flux can be observed, up to
!>    1.2 Km/s, which seem to be not realistic.
!>
!> @todo Output of _av variables in case of restarts
!> @todo Revise flux conversion in energy-balance solver
!> @todo Check optimizations for RMA operations
!> @todo Alternatives for MPI_WIN_ALLOCATE? (causes problems with openmpi)
!> @todo Check for load imbalances in CPU measures, e.g. for exchange_horiz_prog
!>       factor 3 between min and max time
!> @todo Check divisions in wtend (etc.) calculations for possible division
!>       by zero, e.g. in case fraq(0,m) + fraq(1,m) = 0?!
!> @todo Use unit 90 for OPEN/CLOSE of input files (FK)
!> @todo Move plant canopy stuff into plant canopy code
