Describes the intermediate grid to which the transform is performed. It may be coincident with the target grid, in which case there isn't a second interpolation and the transform is direct to target grid.

It may be coincident with the target grid, in which case there isn't a second interpolation and the transform is direct to target grid.
Possible values are
| Value | Description | |
|---|---|---|
| NONE | Disables any truncation before the transformation
| |
| AUTO | Truncation is derived from the intermediate grid. This is the default behaviour | |
number | Specific truncation to be applied, e.g. TRUNCATION=179 truncates input SH field to T179 | |
| OFF | reserved MARS value that resets the value inherited, effectively removing the keyword from the request. In this case results in AUTO being applied. |
