    88The current version of UKESM1 has an atmospheric resolution of N96 (~140 km) and a one degree resolution in the ocean.  The vertical resolution is 85 levels in the atmosphere and 75 levels in the ocean.  
    99 
    10 The model is distributed and run as a [wiki:RoseCylc Rose] suite.  A number of different configurations of the model are available, described in the following subsections

    14 === historical, pre-industrial control 
    15  
    16 There are two fully coupled UKESM1 configurations which each make use of all model components: one with science settings for a historical experiment, and one with settings for a pre-industrial control experiment.

    21 === abrupt4xCO2, 1%CO2 
    22  
    23 Configurations for abrupt4xCO2 and 1%CO2 experiments can be created using the pre-industrial control experiment as a starting point. 
    24  
    25 To create a suite for the abrupt4xCO2 experiment, first make a copy of the  [https://code.metoffice.gov.uk/trac/roses-u/browser/b/c/9/6/4/trunk pre-industrial control suite], then in `um -> namelist -> UM Science Settings -> Section 01-02 - Radation -> GAS MMRs`, set `co2_mmr=1.72728e-03`.

    27 To create a suite for the 1xCO2 experiment, first make a copy of the  [https://code.metoffice.gov.uk/trac/roses-u/browser/b/c/9/6/4/trunk pre-industrial control suite], then in `um -> namelist -> UM Science Settings -> Section 01-02 - Radation -> GAS MMRs -> Varying gas MMRs`, set `l_clmchfcg=.true.` to enable time-varying GHGs.  Finally, in the sub-panel `Varying CO2 MMRs`, set

    3717See [#Sciencenotes below] for more on the science settings of the model. 
     
    4121By default, each UKESM1 suite is set up to run the model on the Met Office HPC.  The suite offers several options for specifying how the model is to be run, including:   
    4222 
    43  * login node to be used for submission to Met Office HPC: `suite conf -> Machine Options -> MetO Cray login node` 
    44  * Met Office queue to which jobs will be submitted: `suite conf -> Machine Options -> HPC queue`   
     23 * login node to be used for submission to Met Office HPC: `suite conf -> Host Machine -> Compute Host` 
     24 * Met Office queue to which jobs will be submitted: `suite conf -> Host Machine -> HPC queue`   
    4525 
    46 Options for specifying the account under which jobs will be run are available in `suite conf -> Project Accounting`: 
     26Options for specifying the account under which jobs will be run are also available in `suite conf -> Host Machine`: 
    4727 
    4828 * Select `Use default account` to use the default account for your department.   
     
    5636==== Monsoon 
    5737 
    58 To run on Monsoon, the Met Office / NERC collaborative platform, set `suite conf -> Machine Options -> Site at which model is being run` to  `MONSooN`.   
     38To run on Monsoon, the Met Office / NERC collaborative platform, set `suite conf -> Host Machine -> Site at which model is being run` to  `MONSooN ('monsoon')`.   
     39 
     40In addition, the generation of supermeans (see `suite conf -> Tasks -> Supermeans`) ''must'' be turned off when running on Monsoon. 
    5941 
    6042Output files created by the suite running on Monsoon may be archived via the Met Office Operational Storage Environment (MOOSE).  The options for requesting this can be found under the `postproc -> Post Processing - common settings` control panel.  Set `archive_command` to `Moose` and provide (or check) values for further options in the subpanel `Moose Archiving`.  See [#Archivingofduplexeddata below] for more on the `non_duplexed_set` option.  
     
    6446==== NEXCS 
    6547 
    66 To use NEXCS, the NERC-only share of Monsoon, set `suite conf -> Machine Options -> Site at which model is being run` to  `MONSooN` and select a NEXCS account for running jobs (see [#Optionsforrunningthemodel above]).  
     48To use NEXCS, the NERC-only share of Monsoon, set `suite conf -> Host Machine -> Site at which model is being run` to  `MONSooN` and select a NEXCS account for running jobs (see [#Optionsforrunningthemodel above]).  
     49 
     50As in the case of Monsoon, the generation of supermeans (see `suite conf -> Tasks -> Supermeans`) ''must'' be turned off when running on NEXCS. 
    6751 
    6852Output files created by the suite running on NEXCS may be archived to disk.  The options for requesting this can be found under the `postproc -> Post Processing - common settings` control panel.  Set `archive_command` to `NEXCS` and provide values for `archive_root_path` and `archive_name` in the subpanel `Archer Archiving` (sic) to specify the location of the archived files on NEXCS.   
     
    7458==== Archer  
    7559 
    76 To run on Archer, the NERC platform, set `suite conf -> Machine Options -> Site at which model is being run` to  `Archer` and set these other `Machine Options`: 
     60To run on Archer, the NERC platform, set `suite conf -> Host Machine -> Site at which model is being run` to  `Archer` and set these other `Machine Options`:
