AMM12 (Atlantic Margin Model 12kms horizontal resolution)

Last edition: Wikinfo(changed_ts)? by Wikinfo(changed_by)?

Configuration description

AMM12 is a regional model covering the Northwest European Shelf domain on a regular lat-lon grid at approximately 12km horizontal resolution. The key key_amm_12km is used to create the correct dimensions of the AMM domain.

This configuration tests several features of NEMO functionality specific to the shelf seas.
In particular, the AMM uses s-coordinates in the vertical rather than z-coordinates and is forced with tidal lateral boundary conditions using a flather boundary condition from the BDY module (key_bdy).

The AMM configuration uses the GLS (key_zdfgls) turbulence scheme, the VVL non-linear free surface (key_vvl) and time-splitting (key_dynspg_ts).

Configuration inputs

Input files can be downloaded here, please notice that the file depends on your NEMO release:

In addition to the tidal boundary condition, the model may also take open boundary conditions from a North Atlantic model. Boundaries may be completely ommited by removing the BDY key (key_bdy) in CONFIG/AMM12/cpp_AMM12_fcm.

Sample surface fluxes, river forcing and a sample initial restart file are included to test a realistic model run. The Baltic boundary is included within the river input file and is specified as a river source. Unlike ordinary river points the Baltic inputs also include salinity and temperature data.
