Stripping chemistry from Snr

Which parts of Snr UM can be removed (we still require storage space for some of the chemistry)?

What has currently been removed?

  • call to UKCA_MAIN1
  • call to EG_CORRECT_TRACERS_UKCA

Snr UM is still about 85% slower than equivalent CLASSIC run.

What still needs removing?

  • Disabling the convective transport of UKCA in NI_CONV_CTL
  • Call to plume scavenging
