1 Additional grids include O192, O800, O912, O2000, O8000.
MARS requests specifying an unsupported grid will fail. For example, a retrieval request with grid=O123
will return an error. If the letter denoting the type of Gaussian grid is omitted, e.g. grid=320
, a full (or regular) Gaussian grid with 320 grid lines is returned.
