Value | Description |
---|---|
NONE | Disables any truncation before the transformation, i.e. uses the archived spectral resolution. |
AUTO | Truncation is derived from the intermediate A formula is used to truncate the spectral series to correspond to the equivalent linear Gaussian grid. This is the default behaviour |
number | Specific truncation to be applied, e.g. TRUNCATION=179 truncates the Spectral harmonics input field to T179. |
OFF | reserved MARS value that resets the value inherited, effectively removing the keyword from the request which results in AUTO being applied. |
