Initialisation

The suite (meteorological, aerochem variables) will initialise from a dump produced at the end of a 20-year spin-up run of the previous GA7.1+Strattrop AMIP run u-au917

Forcing data

Emissions

Emissions for aerosol and chemical species (except biogenic) are prescribed as monthly cyclic climatologies around Year2000 by averaging data for 1995-2004 from the CMIP6 historical emissions developed for UKESM1. Script used was make_clim_emiss.py.

Biogenic emissions used are those originally developed for the NERC ACSIS project and represent datasets pertaining to 1990s,2000s for different species.

Sea surface temperature and sea ice concentrations

The SST and Sice values are also prescribed as monthly climatologies for 2000 created by averaging over 1995-2004 the timeseries data generated for CMIP6 Atmos-only simulations.

GHG and Trace Gas Concentrations

  • These have been specified as values averaged over 1995-2004 from the historical GHG forcing data prepared for CMIP6.
  • This was done by manually averaging data for above years from the files {{{/projects/ancils/cmip6/ancils/any/timeseries_1850-2014/cmip6/global_ghg_cmip6.conf}}} and {{{trgas_rcp_historical.dat}}} respectively for the Radiation GHG inputs and UKCA trace gas specification.

Scaling Tests

Scaling tests of GA7.1+StratTrop free-running configuration have been performed on the XCS and ARCHER using UM vn10.6.1. Scaling plots are below.

Monsoon2 changes including MOOSE archiving

You will likely need to correctly set your Monsoon2 project and MOOSE project name in the suite. To do this go to suite conf Host Machine Met Office / Monsoon. You should then:

  • Set Account_Monsoon to the correct value, e.g. ukca-cam etc.
  • Put the correct MOOSE project name if required, e.g. ukca. Your Monsoon2 MOOSE project will be of the form project-NAME, and you only need to enter NAME here.
  • If you do not yet have access to MOOSE, please contact monsoon "at" metoffice.gov.uk.

NEXCS changes including JASMIN archiving

Setting your NEXCS project

You might need to correctly set your NEXCS project in the suite and at the top of the rose-suite.conf as currently this is set to nexcs-n02 in both places.

For the suite go to suite conf Host Machine Met Office / Monsoon. You should then:

  • Set Account_Monsoon to the correct value, e.g. nexcs-n01 etc.

The changes to rose-suite.conf must be made at the top of the file, where the lines

root-dir{share}=*=/projects/nexcs-n02/$USER
root-dir{work}=*=/projects/nexcs-n02/$USER

are, and change the nexcs-n02 to be the appropriate project.

JASMIN archiving using pptransfer

The suite is currently configured to use the pptransfer task to archive the data to JASMIN. The Archer Archiving panel is used to copy the data to $SCRATCH as the model runs. Note that this data may be deleted so it is essential that it is copied elsewhere as described below.

To be able to copy the files to JASMIN you should do the following:

  • Set the value of transfer_dir to be the path to a JASMIN Group Workspace, e.g. /group_workspaces/jasmin2/ukca/vol1/Juserid/archive, where Juserid is your JASMIN userid. You can apply for access to a GWS on the JASMIN website.
  • Set the value of remote_host to be the transfer machine on JASMIN to use, e.g. jasmin-xfer1.ceda.ac.uk or jasmin-xfer2.ceda.ac.uk. Using jasmin-xfer2 is recommended but you must first request access to hpxfer.
  • You should contact cms-support "at" ncas.ac.uk for advice as to how to connect to JASMIN from the XCS.

ARCHER archiving to the RDF and JASMIN

The ARCHER suite has been configured to allow for automatic archiving to the RDF (/nerc disk) and a JASMIN Group Workspace if required. These settings are found in the postproc Post Processing and then either select Archer Archiving or JASMIN Transfer.

u-ba915 running, showing the postproc and pptransfer tasks in use.

Archer Archiving using the postproc task

  • Set the value of archive_root_path to be on the /nerc disk, e.g. /nerc/n02/n02/Auserid/archive, where Auserid is your ARCHER userid.
  • Turn on archiving via the postproc task, by clicking the suite conf Tasks Post Processing button.

JASMIN Transfer using the pptransfer task

  • Ensure that you have archiving to the RDF turned on using the postproc task (see above).
  • Set the value of transfer_dir to be the path to a JASMIN Group Workspace, e.g. /gws/nopw/j04/ukca_vol1/Juserid/archive, where Juserid is your JASMIN userid. You can apply for access to a GWS on the JASMIN website.
  • Set the value of remote_host to be the transfer machine on JASMIN to use, e.g. jasmin-xfer1.ceda.ac.uk or jasmin-xfer2.ceda.ac.uk. Using jasmin-xfer2 is recommended but you must first request access to hpxfer.
  • You will need to ensure that you can connect from PUMA to the RDF data transfer node (e.g. dtn02.rdf.ac.uk).
  • You will need to ensure that you can connect from the data transfer node to JASMIN.
  • You will need to ensure you include the following in your RDF ~/.ssh/config file:
Host jasmin-xfer2 jasmin-xfer2.ceda.ac.uk
	Hostname jasmin-xfer2.ceda.ac.uk
	User Juserid
	IdentityFile ~/.ssh/id_rsa_jasmin
	ForwardAgent no

Host jasmin-xfer1 jasmin-xfer1.ceda.ac.uk
        Hostname jasmin-xfer1.ceda.ac.uk
        User Juserid
        IdentityFile ~/.ssh/id_rsa_jasmin
        ForwardAgent no
where Juserid is your JASMIN userid. You should replace ~/.ssh/id_rsa_jasmin with the path to your JASMIN SSH key (if it is named differently).
  • You will need to ensure that you have the following in your PUMA ~/.ssh/config file:
Host dtn02 dtn02.rdf.ac.uk
        Hostname dtn02.rdf.ac.uk
        User Auserid
        IdentityFile ~/.ssh/id_dsa
        ForwardAgent no
where Auserid is your ARCHER/RDF userid. You should replace ~/.ssh/id_dsa with the path to your ARCHER SSH key (if it is named differently).
  • Turn on the pptransfer task by clicking the suite conf Tasks PP Transfer button.

Remember to always COPY these suites to a new one that you own, rather than checking them out. This will prevent you accidentally over-writing the settings in the original suite.

Changes to convert a Free-running job to Nudged

1. Copy (rosie copy) a Free-running job

2. cd ~/roses/<new suite> and rose edit --> suite-conf --> Model configuration --> Select Gregorian

3. Panel --> um --> namelist --> UM science settings --> Sec 39- Nudging --> set:

4. Panel > um --> namelist --> Model Input and Output --> STASH requests --> STASH requests
Add a Stash request for 30-451 (Pressure at Tropopause level)with DIAG, TALLTS, UPUKCA profile.
You can also add Nudging diagnostics - (Section 39 :39001,003,006,008,011,013) to help identify any problems in this setup.

5. Edit file app/um/opt/rose-app-gregorian.conf and replace:

  - The ancilfilename for Sea surface temperature (usu SST_ANCIL_FILE) with location of the Gregorian Tslice2000 SST file e.g. $SST_SICE_ANCIL/sst_mon_clim_2000_n96e_grg.anc
  - The ancilfilename for Sea Ice (usu SICE_ANCIL_FILE) with location of the Gregorian Tslice2000 Sice file e.g. $SST_SICE_ANCIL/sice_mon_clim_2000_n96e_grg.anc
  $SST_SICE_ANCIL should already be set in your suite.

6. In same file: Manually activate the meanfreqim= item i.e. remove the !! prefixing the item.

7. Edit app/um/rose-app.conf and replace two files from the ukca_em_files list:

  - $UM_NETCDF_UKCAEMISS_SO2_NAT_DIR/UM_NETCDF_UKCAEMISS_SO2_NAT_FILE with $CMIP6_AEROCHEM_EMS/aerocom/ukca_emiss_SO2_nat_grg.nc
