- 0.125 x 0.125 degrees latitude-longitude grid, or multiples thereof

- any spectral truncation (current model resolution is T1279)

- the Gaussian grid appropriate to the forecast model in use. The following Gaussian grid numbers are supported: 640, 400, 256, 200, 160, 128, 80, 48 and 32

- any sub-area

Additionally, as an interim measure, polar stereographic grid systems as defined in Appendix I section 2, are also supported.
