1MODULE tracco2i_mod
2!
3! This module does the work for the interactive CO2 tracers
4! Authors: Patricia Cadule and Olivier Boucher
5!
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
13!
