Static fields are archived only as of the analysis type. For users' convenience, even they are invariant fields, they should be archived for all analysis output times. In case of ensemble products they should be archived with all ensemble members (again as of the analysis type only). The surface roughness could be either static or changing parameter depending on model and should be handled accordingly as a static or a prognostic model field. |

The soil depth could be either a constant or a grid dependent parameter depending on given model soil scheme. If constant, the soil depths should be mentioned only in documentation of given model. If grid dependent it should be archived the same as other static fields for all analysis output times. In case of ensemble products it should be archived with all ensemble members (again as of the analysis type only). |
