Abstract (AI)
Abstract. SURFEX is a new externalized land and ocean surface platform that describes the surface fluxes and the evolution of four types of surfaces: nature, town, inland water and ocean. It is mostly based on pre-existing, well-validated scientific models that are continuously improved. The motivation for the building of SURFEX is to use strictly identical scientific models in a high range of applications in order to mutualise the research and development efforts. SURFEX can be run in offline mode (0-D or 2-D runs) or in coupled mode (from mesoscale models to numerical weather prediction and climate models). An assimilation mode is included for numerical weather prediction and monitoring. In addition to momentum, heat and water fluxes, SURFEX is able to simulate fluxes of carbon dioxide, chemical species, continental aerosols, sea salt and snow particles. The main principles of the organisation of the surface are described first. Then, a survey is made of the scientific module (including the coupling strategy). Finally, the main applications of the code are summarised. The validation work undertaken shows that replacing the pre-existing surface models by SURFEX in these applications is usually associated with improved skill, as the numerous scientific developments contained in this community code are used to good advantage.
Key Findings
1
It supports offline 0-D and 2-D simulations and coupling with mesoscale, numerical weather prediction, and climate models.
2
SURFEX simulates momentum, heat, and water fluxes, as well as carbon dioxide, chemical species, continental aerosols, sea salt, and snow-particle fluxes.
3
SURFEXv7.2 is an externalized platform simulating surface fluxes and evolution across nature, urban, inland-water, and ocean surfaces.
4
The platform uses shared, validated scientific models across offline, coupled, and data-assimilation applications to unify research and development.
5
Validation indicates that replacing previous surface models with SURFEX generally improves application skill through its integrated scientific developments.
