Action: JM to open ticket
  1. (ongoing) CJ to email LA re problems with SO2 diagnostics for emissions. Issues related to using ASAD diagnostics package. - ongoing
  2. (ongoing) CJ to put branch on PUMA email CMG location of branch to check details - ongoing
  3. (in progress) GM check 8.4 versus 7.3 GLOMAP-mode code and report any bug fixes to Mohit. - in progress(eye on GLOMAP-mode next version)
Change of action: GM to now add to bugfixes page rather than emailing MD.
  1. (ongoing) FOC to add in status and ticket numbers to each item (re: UKESM1 strategy document) - in progress
ownership transferred to Alistair Sellar who will add UKESM1 tickets. UM tickets done separately, and ticket numbers are recorded in UKESM1 tickets.
  1. (ongoing) FOC/NB/GM - discuss (9) offline (re: GLOMAP-mode coupling to FJX) - Apostolos Voulgarakis could also be included in this. Could this also link to the heterogenous chemistry task?
  2. (ongoing) ALL - feed in to FOC list of priorities. Items need an owner if people need it raised.
  3. LA to monitor NCAS-CMS plans for Rose stem, possibly ask for a subset
  4. (not done) Incorporate Bug #35 into dry deposition work - Federico Centoni (FC) wants to do some sensitivities - hold off until FCs assessment
  5. (ongoing) Bug #36 (ozone): FOC/Steven Hardiman to take on - see MOSRS ticket #102 (UKCA Bugfix for ozone column diagnostic calculation)
  6. FOC/MD to open some tickets and add them to the bugfixes page, also there are some from Action/Task 4 from Previous Meetings which need adding.
  7. GM/MR to update bugfix page with their bug involving model_levels/wet_levels (will there even be a distinction in future, and/or could we just add a trap on this?)
  8. NS to check with Glenn Greed about wet_levels.
  9. (ongoing - standing item) CMG to monitor list of bugs and circulate between group for owners

  16. MD to email AS and ask about netCDF emissions apps at vn10.1.
  17. Bug #31: NS to outline possible options and to open a ticket
  18. Bug #38: GM to take on lodging this on the trunk
  19. Bug #41: FOC to follow this up and see if the netCDF code deals with this.

  21. ALL with access to keep monitoring ukca_bugs email list.
  22. MR to send NS his vn8.6 branch.
  23. NS to contact MR about this work as it might impact him
