 !
 ! This module does the work for the interactive CO2 tracers
+! Authors: Patricia Cadule and Olivier Boucher
+!
+! Purpose and description:
+!  -----------------------
+! Main routine for the interactive carbon cycle
+! Gather all carbon fluxes and emissions from ORCHIDEE, PISCES and fossil fuel
+! Compute the net flux in source field which is used in phytrac
+! Compute global CO2 mixing ratio for radiation scheme if option is activated
+! Redistribute CO2 evenly over the atmosphere if transport is desactivated
