The NEMO model

A few specificities of the forced NEMO configurations associated with their use with libIGCM are detailed in this section.
Further information on these configurations (description, setup, documentation) is available on the official NEMO website: http://www.nemo-ocean.eu

To access this information you must create an account in the NEMO users' base and login with it to have detailed information about NEMO.

1.1. Model version

The choice of forcings used for the simulations depends on the model version. The available forcings correspond to NEMO versions for now is v3.6_stable

OPA_version=v3.6_stable is the version where to find all the data needed to perform de csimulatin
mesh_mask=n to output the grid ( named mesh_mask.nc)
OutputLevel?=10 ( the level of the output you : 10 == full ; 1 == less )

}}}

1.2. Simulations

Two kinds of simulations with forced NEMO can be performed:

a climatological simulation
an interannual simulation

1.3. Atmospheric forcings

For forced ocean simulations, you need the atmospheric forcings for the :

wind stress - zonal and meridional
air temperature
solar and non solar fluxes (shortwave and longwave)
relative humidity
precipitations (solid: snow and liquid: rain)

To specify in the Interannual section

1.4. Initial states and boundary conditions

The initial states and the boundary conditions are listed in the Boundary Files section
All those files are described on the official NEMO website: http://www.nemo-ocean.eu/Using-NEMO/Configurations/ORCA2_LIM, section Configuration Inputs

2.1. Initial states and boundary conditions

The initial states of a few passive tracers come from monthly (NO3, PO4, O2, Si) and annual (DIC, Alkalinity) climatologies or from simulation outputs (Iron, DOC). The other PISCES tracers are initialized by constant values in the model.
the files containing the external nutrient uptake are also listed below:
- DUST_INCA_LOI6012-histAER_1M_${year}.nc : interannaul file of the nutrient uptake by dust derived from the INCA model
- pmarge_etopo_eORCA_R1.nc : annual climatology of iron uptake by sediments
- river_global_news_eORCA_R1.nc : annual climatology of nutrient uptake by rivers
- Ndep_input4MIPs_surfaceFluxes_CMIP_NCAR-CCMI-2-0_gn_${year}01-${year}12-clim.nc : interannual files of nitrogen deposit derived for the input4MIPS database
- Solubility_T62_Mahowald_eORCA_R1.nc : solubility of iron
