== Configuration description

AMM12 is a [http://www.tandfonline.com/doi/pdf/10.1080/1755876X.2012.11020128 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.[[BR]]
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).

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.[[BR]]
