! Purpose: compute convective fluxes for FLDTRAN radiation model, and 
!          add them to dissipation in order to obtain the residual.
!
! Description: none.
!
! Input: region = data of current region.
!
! Output: region%levels%radi%rhs = radi convective fluxes + radi dissipation.
!
! Notes: none.
