Start dump for present day

Description

Hi

I want to run a global coupled model, starting from present-day, on Monsoon (xcsc). I have a copy of the standard suite for a pre industrial control (GC3.1, vn 10.7, suite id: ar-930, from Standard configurations http://cms.ncas.ac.uk/wiki/UM/Configurations/GA7.0-GC3.0) but I would like to start it with a present-day start dump (eg 2014 - any year from 2012 would be fine). Do you know where I could find appropriate start dumps? Or is there another suite that is already set up in this way that I could use?

Thanks,
Laura

  • Platform set to Monsoon2
  • UM Version set to 10.7

Hi Laura,

There is a 2015 atmosphere start dump in /projects/nexcs-n02/frmy/2015032300_glm_t+0. Will that do?

Regards
Willie

Hi Willie

Thanks for this, I will try that one. Do I also need to change the NEMO and CICE start dumps? e.g. suite-conf>Run Initialisation and Cycling>NEMO start dump: /projects/ukesm/jwalton/startdumps/u-aq853/aq853o_25940101_restart.nc
and there are also files from the same folder in NEMO icebergs start dump and CICE start dump. Should these files also be edited to 2015 versions?

Thanks,
Laura

  • Keywords coupled model start files, NEMO, CICE added

Hi Laura,

Is this still a problem?

Willie

Hi Willie,

Yes - but more a clarification problem than a technical problem. I am a bit confused about what needs to be changed to get the model running with the right start dumps? I want to run the coupled model with present-day initial conditions.

Thanks

  • Keywords CICE, ocean dumps added; CICE removed

Hi Laura,

After rooting around on MASS I managed to find a source of ocean dumps. To match the atmosphere dump, I did,

moo get moose:/opfc/ocn/global/rerun/201503.file/2015032300* .

and then transferred these files to ARCHER in /work/n02/n02/wmcginty/2015032300_ocean where I have unpacked the tar files. Please copy these to you own work space as soon as possible.

I have no idea which of these you need to start the coupled model. You should get advice from someone who knows the science. Let me know if you find this useful.

Hi Willie,

Sorry, I am running on Monsoon and don't have access to ARCHER. Would it be possible to put the files on Monsoon?

Thanks

Hi Laura,

They are on /projects/nexcs-n02/frmy/2015*.

Hi Willie,

Thanks for that. Copied them over to my space. Will keep you updated. By the way, who would you recommend asking for advice about the science for this model set up?

Thanks,
Laura

If you are OK with a 1960 start date maybe you could use data in the UKESM suite u-bc409 - is 1960 considered present day?

Hi Grenville,

Thanks for your reply. I think 1960 might be a bit too early. Do you know of any suites with a 2012 or later start date?

Thanks,
Laura

Hi Laura,

You could try the UKESM team, perhaps Till Kuhlbrodt or Robin Smith.
