Grib file containing the fix fields related to the 10-km QBOLAM model (operational at the Italian Environment Agency, Rome, Italy). The file contains the following fields, for 48h forecast only with a time step of 1h:
- longitude, degrees E
- latitude, degrees N
- Geometrical height of earth surface amsl (m)
- Geopotential of earth surface (m**2/s**2)
- Land-sea mask.
It does not include the height of the pressure levels since this is not a fixed field (QBOLAM is a sigma-vertical coordinate, hydrostatic model, so that geopotential is a predicted 3D field). For the reason the 3D-geopotential field over the model levels has been included into the mptq grib files. See the model mptq grib file description. Actually, such a field (divided by 9.81) provides the geometrical height on which all the other available variables on the model levels are defined.
