= The Single Column Model =

The Met Office Single Column Model is described in [https://code.metoffice.gov.uk/doc/um/latest/papers/umdp_C09.pdf UMDP C09] on the Met Office Science Repository web site (login required).

== Old versions of the SCM UM8.x ==
These are set up in the UMUI, which transfers code across to ARCHER for the user to run manually. 

These can be run on ARCHER using the method outlined on the CMS web site at [http://cms.ncas.ac.uk/wiki/Archer/SCM Running the SCM on ARCHER].

== Later versions of the SCM ==
The later versions of the SCM UM  10.x+ use the !Rose/Cylc framework and are expecting to run in a full UM environment.

The SCM runs as a parallel process on a computer.  It requires the following

 * an installation of FCM, Rose and Cylc 
 * a version of MPI
 * a Fortran 2003 compiler
 * a build of GCOM
 * a build of the shared UM library (for versions prior to 11.3)
 * a version of netCDF

=== ARCHER ===
There is an ARCHER version of the TOGA-COARE SCM model.  This is suite u-bf976 which is a UM11.1 version.

On ARCHER it uses the following modules,

 * Compiler,  intel/17.0.0.098,
 * MPI,  cray-mpich/7.5.5,
 * netCDF, netcdf/4.3.2

=== JASMIN ===
The JASMIN version of the TOGA-COARE SCM is currently in development (May 2019).
