| Type of Level | Units | Description |
|---|---|---|
Soil level | - | This level represents a soil model level (similar to hybrid model level above surface). The scaled value encoded together with this new type of level represents the level number. The aim of this type of level is to encode a soil level that has not a constant depth across the model domain (each grid cell has soil levels of different depths). The non-constant depth is then encoded as a parameter on this type of level alongside the other parameters like temperature, soil moisture, etc. A "soil layer" (useful to encode volume integrated parameters) can be represented by defining 2 soil model levels using the usual GRIB2 mechanism ("first fixed surface/second fixed surface" where the deepest soil level is always encoded as the second fixed surface). |
