The current primary objective: minimising any degradation in science

What needs to be done to achieve this?

  • Lock the physical atmosphere of Jnr to Snr as best as possible
    • Decoupling Jnr->Snr is helpful, i.e. all science is run in Snr, but Jnr is still locked to Snr
      • We want Jnr to match Snr as much as possible
      • (Aside: I think this could be good method of tuning different resolutions in general)
    • Decide which dynamical core fields should be used to lock Jnr to Snr (even if we have a few variations)
    • Tune N48 Jnr/N216 Snr (the N96 UKESM should already be tuned)
      • Spin-up the software engineers. I need to understand at least enough of the science to understand what the tunings are doing.
  • A long PI and historical run
