COUPLED MODEL (CNRM-CERFACS) : Arpege v5 (t127,c127) - Nemo v3 (tne1,une1,vne1,rne1) - Trip (trip,trpe) - OASIS3

The results are presented in the table below. For each couple of grids, different interpolations are tested.
The interpolated field correponds to the analytical function f :

For each interpolation, the source field, the target field and the error field are presented.
The points at 0 correspond to points in the target field that do not receive any value (masked points).

RESOLUTIONS : t127 = 24572x1 ; c127 = 24572x1 ; (tuvr)ne1 = 362x292 ; trip = 360x180 ; trpe = 360x180
