MARS/Dissemination
To select a specific method for the interpolation of gridded fields.

MIR does not support the 12-point interpolation method, used by EMOSLIB for rotated grids. Therefore, the default interpolation method used is the linear. Rotated spherical harmonics are not supported in MIR or EMOSLIB.
Also, note that all "Spectra-related" parameters have been classified and are interpolated in the same way as the 2D spectra, using a nearest neighbour in MIR instead of EMOSLIB's bilinear method.
When interpolating the land-sea mask field, MIR returns fractional values greater than or equal to 0 and less than or equal to 1. Users should regard land-sea mask values greater than or equal to 0.5 as representing land points and those less than 0.5 as representing sea points.
Possible values are
| Value | Description |
|---|---|
| linear | Linear interpolation. This is the default behaviour. |
| bilinear | Bilinear interpolation. Results |
nearest neighbour | Choosing the nearest grid point. |
| nearest lsm |
