−
# Generation of aerosol as well as chemistry diagnostics for CMIP6
  
−
# Activating Water vapour feedback from UKCA (involves moving location of UKCA call)
  
−
# Increase number of UKCA tracers (current branch/ implementation allows upto 255, after which it clashes with LBC 'tendancy' tracers)
  
−
# UKCA StratTrop NRUN-CRUN bit-reproducibility issue - inputs to solver are being checked first, followed by solver issues themselves
  
−
# Reduce vertical extent of Dry deposition calculations - will be lodged on a switch and subsequently evaluated for GA/UKESM
  
−
# Columnar approach/ OpenMP in GLOMAP: Current method hardwired to lat/long decomposition, Optimisation team have asked for more flexibility

Based on experience with vn7.3 Nitrate configuration, FOC to recommend to Exec that any new UKCA configuration should only be distributed after specified (e.g. rose-stem) testing, assessment and followed by approval from CMG.

Also, once the GA7.1 configuration with offline oxidants is frozen, both FOC and JM propose that the interactive chemistry is activated and evaluated with a view to making that configuration a formal scientific release of UKCA. Actions noted above.

Actions from this meeting

One off actions

Standing actions

  1. (ongoing - standing item) CMG to monitor list of bugs and circulate between group for owners.
  2. (ongoing - standing item) At CMG future meetings there should be included an appendix listing the open bugs. If a ticket is included it is not an open bug (as the owner of ticket is person doing lodging).
  3. (ongoing - standing item) JM to continue to link/send powerpoint results (re: GA7.0/GA7.1), as new configurations released and link/put files on UKCA wiki.
  4. (ongoing - standing item) ALL with access to keep monitoring ukca_bugs email list.
  5. (ongoing - standing item) ALL to think about if code changes will change KGO and let systems team know in good time. This should be a standard part of our working practice.
