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 the target grid is direct.
Possible values are
| Value | Description | ||
|---|---|---|---|
| NONE | Disables any truncation before the transformation
| ||
| AUTO | Truncation is derived from the intermediate gridAn intermediate FULL Gaussian grid is used, derived from the output GRID, by looking at the equivalent resolution. This is the default behaviour. | ||
number | Specific truncation to be appliedSpecifies the intermediate grid, e.g. TRUNCATION=179 truncates input SH field to T179. O80 for an Octahedral Gaussian with 80 lines between Pole and Equator. | ||
| OFF | reserved Reserved MARS value that resets the value inherited, effectively removing the keyword from the request . In this case which then results in intgrid being set to AUTO being applied. |
