| 5 | %% Common part between NEMO-SI3-TOP |
---|
| 6 | ``Tracers in Ocean Paradigm'' (\TOP) is the passive tracers engine of |
---|
| 7 | the \NEMO\ ocean model (``Nucleus for European Modelling of the Ocean''). |
---|
| 8 | It is intended to be a flexible tool for studying the on/offline oceanic tracers transport and |
---|
| 9 | the biogeochemical processes (``green ocean''), |
---|
| 10 | as well as its interactions with the other components of the Earth climate system over |
---|
| 11 | a wide range of space and time scales. |
---|
| 12 | \TOP\ is interfaced with the \NEMO\ ocean engine, and, |
---|
| 13 | via the \href{http://portal.enes.org/oasis}{OASIS} coupler, |
---|
| 14 | with several atmospheric general circulation models. |
---|
| 15 | %It also supports two-way grid embedding by means of the \href{http://agrif.imag.fr}{AGRIF} software. |

| 17 | %% Specific part |
---|
| 18 | This component provides the physical constraints and boundaries conditions for |
---|
| 19 | oceanic tracers transport and represents a generalized, hardwired interface toward |
---|
| 20 | biogeochemical models to enable a seamless coupling. |
---|
| 21 | In particular, transport dynamics are supplied by the ocean dynamical core thus |
---|
| 22 | enabling the use of all available advection and diffusion schemes in both on- and off-line modes. |
---|
| 23 | \TOP\ is designed to handle multiple oceanic tracers through a modular approach and |
---|
| 24 | it includes different sub-modules: ocean water age, inorganic carbon (CFCs) \& radiocarbon (C14b), |
---|
| 25 | built-in biogeochemical model (PISCES), and prototype for user-defined cases or |
---|
| 26 | coupling with alternative biogeochemical models (\eg \href{http://www.bfm-community.eu}{BFM}). |
