 * Alternative methods of spatial interpolation for translating variables between different model grids may be used without the addition of more bespoke code to GENIE.  Sensitivity of the GENIE framework to different methods of interpolation -- for instance nearest-neighbour, bilinear, or bicubic -- can be investigated and assessed.
-The GENIE earth system modelling framework will incorporate the [http://prism.enes.org/ Program for Integrated Earth System Modelling (PRISM)] coupler, OASIS.  The OASIS coupler is part of the PRISM community standard tool set for earth system models, and will enable the coupling of full complexity models in future.  The "glue code" holding the framework together will be generated by the [[GENIE:BFG|Bespoke Framework Generator (BFG)]].  BFG will help insulate GENIE models from changes in OASIS (or allow the use of a different coupler in future).
