.. _ARPNH-DYAMOND-WINTER:

ARPEGE-nh
========================================

**Provided by**  Météo-France, FR


Model description
-----------------

ARPEGE-nh is the non-hydrostatic version of the Météo-France operational configuration that inherits features from both the ARPEGE/IFS global model and the AROME non-hydrostatic Local Area model.


Experiment runs
-----------------

ARPEGE-nh 2.5km atmosphere-only

        :file:`/fastdata/ka1081/DYAMOND/data/winter_data/DYAMOND_WINTER/METEOFR/ARPEGE-NH-2km/DW-ATM/`
        with grid files contained in :file:`atmos/fx/`
Setup: 
        Atmosphere-only
Resolution:
        * horizontal grid spacing of 2.5km, comprising 16848632 grid columns, with spectral truncation T8000
        * number of vertical levels for the atmosphere: 75
Comments: 
        * Similar the ARPEGENH 2.5km simulation for DYAMOND-Summer (see `Stevens et al. 2019 <https://doi.org/10.1186/s40645-019-0304-z>`__), but with an important improvement using microphysics from the LAM model AROME, specially tuned for high resolution non-hydrostatic modeling.
