MODULE phytrac_mod
  !=================================================================================
  ! Interface between the LMDZ physical package and tracer computation.
  ! Chemistry modules (INCA, Reprobus or the more specific traclmdz routine)
  ! are called from phytrac.

  ! iflag_vdf_trac : Options for activating transport by vertical diffusion :
  !     1. notmal
  !     0. emission is injected in the first layer only, without diffusion
  !    -1  no emission & no diffusion
  ! Modification 2013/07/22 : transformed into a module to pass tendencies to
  !     physics outputs. Additional keys for controling activation of sub processes.
  ! Modification R. Pilon 10 octobre 2012 large scale scavenging incloud_scav + bc_scav
