! Module atmos_ocean_fluxes_mod
!
! This module will take fields from an atmospheric and an
! oceanic model and calculate ocean surface fluxes for
! CO2, O2, CFC-11 or CFC-12 as outlined in the various
! HOWTO documents at the OCMIP2 website. Multiple instances
! of a given tracer may be given, resulting in multiple
! surface fluxes. Additionally, data may be overridden at
! the individual fields, or fluxes. This could be used in
! the absence of an atmospheric or oceanic model.
