UKESM start dump

Reported by: ChrisWells Owned by: um_support
Component: UKESM Keywords: science
Cc: t.kuhlbrodt@…, yongming.tang@… Platform: Other
UM Version:



I'm going to use UKESM to do emissions perturbations, but I'm unsure what I should use as start dumps.

I notice that UKESM has run the CMIP6 historical simulations, leading up to the present day, but clearly this climate isn’t in equilibrium. (

I also see that HadGEM3 N96ORCA1, the core of UKESM, has been ran present day for at least 750 years. While this is in equilibrium, I don’t think (and could be wrong) that this is exactly UKESM, so UKESM wouldn’t be in equilibrium if ran with the output of this. ( )

Do you know:

  1. Can I access and use start dumps from these runs?
  2. Which one would be best to use for my simulations? Or if something else would be better?

Many thanks for any advice on this,

Hi Chris,

I think these questions might be better addressed to the UK ESM team (cc'd)

Hi Chris,

Scientific queries relating to UK ESM should be addressed to Yong Ming Tang at the Met Office (also cc;d).

Hi Willie,

Sorry, not sure why this ticket has been closed? I haven't had an answer yet - should I email Yong Ming Tang separately?

Yes you should.
