6  ! Purpose and description:
7  !  -----------------------
8  ! Main routine for the interactive carbon cycle
9  ! Gather all carbon fluxes and emissions from ORCHIDEE, PISCES and fossil fuel
10  ! Compute the net flux in source field which is used in phytrac
11  ! Compute global CO2 mixing ratio for radiation scheme if option is activated
12  ! Redistribute CO2 evenly over the atmosphere if transport is desactivated
