Actions from this meeting

Minutes

Actions from the Last Meeting (LA)

Minutes of the code management group meeting 2017-07-14

One off actions

  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) FOC to incorporate Bug #35 and others into dry deposition work. FOC to draft document that will cover what the new deposition scheme will do
  3. (ongoing) LA to migrate PUMA UM tickets to MOSRS - see table below
  4. (new) ALL to check through this table and comment on whether the tickets needs to be ported or not. Deadline 2017-07-28
  5. (new) LA to open tickets for all changes that still require a ticket
  6. (ongoing) JM,BJ,NB to discuss incorporation of Nicolas' RADAER description into UKCA (or separate UMDP). JM to take lead.
  7. (ongoing) FOC to open ticket + Bugfixes Table entry related to 'Unable to calculate tropopause' warnings
  8. (ongoing) FOC to recommend at next Exec meeting a policy of allowing only CMG to (certify and) distribute any UKCA configurations for science purpose.
  9. (new) LA (& others who are interested) to look into how to re-organise the UKCA panel (e.g. into sub-panels)
  10. (new) LA to organise a follow-up meeting of interested parties on the UKCA panel re-organisation
  11. (new) MD to collate all UKCA parameters into ukca_constants in advance of removing duplicates already available in the UM
  12. (new) LA to add comments on rafeps into #368
  13. (new) FOC to close #2358 (Delete 2D photolysis scheme in UKCA)
  14. (new) MD to take ownership of #142 (Remove old emissions system from UKCA)
  15. (new) FOC to take ownership of #2356 (Delete older dry deposition scheme in UKCA)
  16. (new) FOC to take ownership of #1507 (Remove Backward Euler Standard Tropospheric Chemistry)
  17. (new) AH to take ownership of #2373 (quick method for calculating wet volume redundant)
  18. (new) LA to take ownership of #1505 (Clean up ukca_strat_update)
  19. (new) JM to clarify with CJ regarding "Wet oxidation of SO2 in GLOMAP"
  20. (new) ALL to note code which is redundant
  21. (new) AH to scope out reducing repetition of mode definitions in GLOMAP
  22. (new) OM to work on the chemistry scheme code restructuring for vn10.8
  23. (new) LA to update Bugs table following discussion, closing tickets where appropriate
  24. (new) FOC to send LA RAQ testing jobs information
  25. (new) MD to set up TS2000 free-running nudged jobs at vn10.8
  26. (new) LA to add UKCA wiki page on using UKCA on the Virtual Machine
  27. (new) LA to create a doodle poll for October after the date of the vn10.9 code freeze

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) ALL with access to keep monitoring ukca_bugs email list.
  4. (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.
  5. (ongoing - standing item) ALL to review and remove obsolete code

Redundant Code (LA for NS)

Redundant code

# Description Ticket Remarks Status Owner
1 Old emissions code (that which uses ancil files) #142 None PROPOSED Nick Savage
2 Old dry deposition scheme #2356 None PROPOSED Nick Savage
3 ukca_volume_mode.F90 - quick method for calculating wet volume is not used since iwvolmethod is hard coded to equal 2. #2373 None Complete Alan J Hewitt
4 2D photolysis #2358 None PROPOSED Nick Savage
5 ukca_strat_update.F90 - relax_ozone #1505 None PROPOSED Nick Savage
6 Backward Euler Standard Tropospheric Chemistry #1507 None PROPOSED Nick Savage
7 Wet oxidation of SO2 in GLOMAP None None PROPOSED Colin Johnson
# Description Ticket Remarks Status Owner
1 Deprecated UKCA netcdf attribute options #2513 'emission_type', string type attributes no longer recomeneded. Need some time for most new code to adopt these DEPRECATED Nick Savage
  • Question: Should all schemes using the backward Euler solver be proposed for redundancy?

Bugs/Bugfixes (LA)

Open Bugs

# Description Ticket Owner Status/ Updates Comments from previous meeting Comments from this meeting
31 FP exceptions in asad_sparse_vars
or asad_spimjmp
#368 (MOSRS) Nick Savage vn10.x seems to be better leave open
35 Error in labelling: Surface resistance <--> stomatal resistance ? MOSRS #1409 Fiona O'Connor folded into DD work leave open & see above
57 Incorrect logic for DMS anciliaries required #756 (MOSRS) Nick Savage trivial. Might close as wontfix, but might want to do in RAQ leave open
72 UKCA Dry Deposition: Surface resistance values
not set for some species
#1250 Alan Hewitt? leave open but there is a way forward
74 Bug in ukca_tropopause with definition of PV tropopause #1283 Steven Hardiman Change ownership? Fix is separate from #75 leave open. FOC did try to lodge, but breaks KGO. Simple fix but with big changes.
75 Bug in STE fluxes #1367 Fiona O'Connor could be endgame leave open. even with fix, these are still wrong
87 Possible issues with YSTORE in UKCA_CHEMISTRY_CTL. UM#3245 Colin Johnson/
Luke Abraham
leave open
88 Potential FastJX Scattering Bug UM#3261 David Wade/
Luke Abraham
leave open
FOC to send LA RAQ jobs information
