==vn10.6 Single Column Model==

**[https://code.metoffice.gov.uk/trac/roses-u/log/a/r/9/8/9/trunk | u-ar989]'''

The Single-Column Model (SCM) is an idealised version of the UM that runs the model on a single grid cell, for debugging as well as investigations of the model physics

This experiment is based off of Met Office SCM template job [https://code.metoffice.gov.uk/rosie/u/query?q=idx+eq+u-aj503 | u-aj503], with modifications to run on Raijin

Documentation on the SCM can be found at [https://code.metoffice.gov.uk/doc/um/latest/papers/umdp_C09.pdf | UMDP C09: Single Column Model]

===Differences from the UKMO version===

Disable building the model by setting the variable `BUILD` to `False` (in rose-suite.conf)

To run in parallel, set PARALLEL_SCM to true. PARALLEL_SCM_DIR should be set to a directory with various SCM namelist files.

For each file in that directory, the SCM will be run using that file as the configuration (the default namelist is /projects/access/umdir/standard_jobs/inputs/default/scm/namelist_HAD.scm)

Each run's output will go to ~/cylc-run/$JOBID/work/scm/1/$(basename $NAMELIST)

===Forcings===

The SCM requires forcing data for the winds, temperature and specific humidity at the location of interest.

This experiment by default reads forcing data from /projects/access/umdir/standard_jobs/inputs/default/scm/namelist_HAD.scm, which has values from the [http://kiwi.atmos.colostate.edu/scm/toga-coare.html | TOGA-CORE] experiment at 19930109T0000Z.
