Actions from this meeting

One off actions

  1. (ongoing) GM check 8.4 versus 7.3 GLOMAP-mode code and report any bug fixes the bugfix page
  2. 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. NS to co-ordinate migration of MetO UM tickets to MOSRS
  5. FOC to find someone to co-ordinate migration of PUMA UM tickets to MOSRS
  6. NS to continue with lodging ticket #368 quick fix. A proposed fix to the value of RAFEPS allowing just one line to have a scaling factor on a namelist has been developed but NS is concerned about implementing it it due to his lack of understanding the code. Implementation will be pending the next action. 
  7. LA to contact Oliver Wild regarding NR solver. In particular to ask advice on the use of the increased value of rafeps to prevent model failures. How safe is this, and is there a better solution?
  8. FOC to check rafeps branch in recent GA7-type runs
  9. (ongoing) Bug #38: GM to take on lodging this on the trunk
  10. (ongoing) LA to check doc for NVOC factor and open ticket to remove it from code
  11. (ongoing) Ben Johnson (BJ) to review OC biomass burning emissions units (#41 in bug table) and if this is now correct, close.
  12. Bug #52: GM to take on lodging this on the trunk
  13. MR to add link to twiki on bugfix page for Bug #53 (RADAER)
  14. FOC to follow up with Irina (CRUM) about progress on time availability codes for UKCA chemistry timesteps
  15. FOC to find owner for UM ticket #987 (Checks in UKCA iBVOC emissions to prevent duplication of online and offline emissions)
  16. CJ to check status of Bug #53 and update table as appropriate
  17. NS to update table for Bug #57.
  18. NS to update table, open ticket and take ownership of Bug #58 (Blocking Mode 3 in FastJX) 
  19. CJ to follow up and update table for Bug #62
  20. NS to review and update table for Bug #68
  21. LA and FOC to resurrect GungHo-UKCA discussions with Mohamed Zerroukat
  22. MD to let people know when Rose suites with StratTrop chemistry and based on the frozen GA7 physics are available
  23. LA to follow up with CMS about copying in both LA and MD in all UKCA and nudging tickets raised with them
  24. LA to arrange next CMG subject to date of next UKCA Exec

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), 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.
