    11 The UM undergoes significant changes as new scientific enhancements are introduced or new features are added and so the [http://www.metoffice.gov.uk Met Office] release new versions regularly (approx. 3-4 times a year). NCAS-CMS only supports a subset of the versions released. A list of the [http://puma.nerc.ac.uk/trac/UM/wiki supported UM versions and platforms] can be found on the [http://puma.nerc.ac.uk/trac/UM/wiki UM Trac].

     19In order to run the climate model, users need to have access to a set of files that will enable them to run a particular scientific version of the climate model (describing exactly the physical and dynamical choices within the UM system).  2 climate model 'families' (HadGEM2 and HadGEM3) are routinely being used and actively developed for climate research by the Met Office Hadley Centre.  These models differ very significantly in terms of their numerical and physical formulation. The Met Office have released several configurations of these models and NCAS-CMS have ported these "standard" configurations to the National HPC HECToR.

     25The UM Fortran source code is available to to view via the [https://puma.nerc.ac.uk/trac/UM/browser UM Trac Code Browser] or alternatively, the UM source code has been converted into a hyperlinked website.

     31The UM is a complex software sytem so a new user should read the documentation available on this web site and complete the [wiki:UmTraining UM training] provided by NCAS. 
     32 
     33The UM software needs to be properly installed so that the scripts, tools, code and files for running an experiment are available. NCAS installs and maintains the supported UM versions on the UK national high performance computers. All NCAS researchers can use the UM on these services, details of getting accounts can be found on this web site. [ [wiki:FAQ_T3_F6 more information .... ] ] 
     34 
     35UM experiments need input files to run and they create output files for diagnosing the experiment. NCAS has created a set of tools and utilities, to supplement the standard ones from the UK Met Office, to support the creation, manipulation and use of these UM files. [ [wiki:ToolsAndUtilities/UmFileTools more information ....] ]
