    18 The main goal of this task is to make model developers and users aware of the important difference existing between a model version and a model configuration. This is a key point to ensure transparency and comprehension of the work done around climate models. The same model version can indeed be used in numerous configurations (physical options, choice of parameterizations, horizontal and vertical grid description and resolution, definition of the initial state...) that can lead to very different results. The model inter-comparisons on which is based a large part of IPCC report from Working group 1, are exploring differences between models. We are here illustrating differences between different configurations of the same model.

The model inter-comparisons on which is based a large part of IPCC report from Working group 1, are exploring differences between coupled models. We are here illustrating differences between different configurations of the same component model.

    4242 1) mask the continents [[BR]] 
    4343 2) fill masked values with neighbouring oceanic values [[BR]] 
    44  3) interpolation on ORCA grid with bilinear (scalar) or bicubic interpolation (vector) [[BR]]

    4646Note that the 3rd point is not absolutely needed as NEMO can perform "on the fly interpolation". The rotation of the vector on ORCA grid is done within the code.
