3 steps to generate atmospheric forcings from ECMWF products for ABL1d model with NEMO:
|
|
- main_uvg_hpg (optional): geostrophic wind or horizontal pressure gradient computation on ECMWF eta-levels (to force ABL dynamics)
|
|
- main_vinterp: vertical interpolation from ECWMF vertical eta-levels to ABL Z-levels
|
|
- main_hdrown: 3D-fields horizontal drowning (extrapolation over land totally inspired from SOSIE by L. Brodeau)
|
|
|
|
Mandatory ECMWF fields: temperature (T), specific humidity (Q), mean sea-level pressure (MSL), wind x-component (U) and wind y-component (V)
|
|
Optional ECMWF fields: surface geopotential (Z)

It is possible to use only necessary ECMWF vertical levels that cover the ABL height.
|
|
For example with ERAI reanalysis, vertical levels from near-surface (L60) to 3100m (L44) are enough to generate forcings for ABL height up to 3000m.

ECMWF ERAI 6h (analysis) forcings on native horizontal grid (Gaussian F128) for the ABL model (50 vertical levels between 10m and 2000m) can be delivered upon request.
