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.

Minutes

Actions from 2016-07-22

  1. (ongoing) GM to check 8.4 versus 7.3 (and possibly vn8.4 vs 10.x) GLOMAP-mode code and report any missing bug fixes on the bugfix page.
  2. (ongoing) GLOMAP-mode coupling to FJX. AA to see if Paul Griffiths can be asked to do this.
  3. (ongoing) FOC to incorporate Bug #35 and others into dry deposition work
  4. (ongoing) FOC/LA to find someone to co-ordinate migration of PUMA UM tickets to MOSRS
  5. UM #368 (RAFEPS value). Error not encountered at UM10.x but LA to consult Oliver Wild regarding background and implications.
  6. (ongoing) Bug #38: MD to lodge the switch for controlling addition of SO2 from explosive volcanoes.
  7. (ongoing) LA to check doc for NVOC factor and open ticket to remove it from code
  8. CJ to lodge STASHmaster changes to diagnostics that should make use of UKCA time availability codes
  9. FOC to supervise work by Joao for UM ticket #987 (Checks in UKCA iBVOC emissions to prevent duplication of online and offline emissions)
  10. (Ongoing)NS to keep Bug #58 (Blocking Mode 3 in FastJX) ticket open but low priority.
  11. NS to update MR on problems encountered due to module-defined variables and OpeNMP in Convection, with possible implications for GLOMAP OpenMP work
  12. CJ,FOC,AH,AS,LA and John H to decide best way forward for implementing GLOMAP-climatology code and documentation.
  13. JM,BJ,NB to discuss incorporation of Nicolas' RADAER description into UKCA (or separate UMDP).
  14. FOC to talk to Paul S. regarding possibility of lodging Mark's basic (hardwired) column-based/ OpenMP approach at UM10.5 and more flexibility in follow-on ticket. NS/Alistair can follow-up.
  15. Bug #72: NS to take a look at Dry deposition/ surface resistance warnings and explore possibility of a quick work-around.
  16. FOC to open ticket + Bugfixes Table entry related to 'Unable to calculate tropopause' warnings
  17. MD to setup Strat+Trop suite as soon as GA7.1 is frozen and also add to Rose-stem.
  18. FOC,JM, others to evaluate above job and ALL to decide about recommending this as the next UKCA Release job.
  19. JM to enquire with David W. regarding addition of GA7.1 to Rose-stem.
  20. CJ to involve NS in discussions with Dynamics and UM-sys teams regarding movement of UKCA call, for effective implementation of water vapour feedback.
  21. FOC to recommend at next Exec meeting a policy of allowing only CMG to (certify and) distribute any UKCA configurations for science purpose.
  22. FOC to set-up Doodle poll for next CMG (possibly for week of 12th September).

Standing items:

  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).
