If this is a direct quote, it should be recorded/formatted as a quote. Ideally we would just rephrase.
| We are developing a new formulation where we would need to archive a set of 3D-fields, instead of a single 3D-fields per physical variable. I think the best way to implement this would be to have a new GRIB variable in the template (i.e. a metadata that contains an integer). This should be then linked to a new MARS key, similar to what is done with the "member" key. | ||
| Let me know what you think, happy to discuss this further and give more details/motivations if needed. | ||
