Open Bugs

#	Description	Ticket	Owner	Comments from previous meeting

31	FP exceptions in asad_sparse_vars or asad_spimjmp	#368 (MOSRS)	Nick Savage	leave open
35	Error in labelling: Surface resistance <--> stomatal resistance ?	MOSRS #1409	Fiona O'Connor	leave open
57	Incorrect logic for DMS anciliaries required	#756 (MOSRS)	Nick Savage	Possibly close: JM to check impact
72	UKCA Dry Deposition: Surface resistance values not set for some species	#1250	Alan Hewitt?	leave open
74	Bug in ukca_tropopause with definition of PV tropopause	#1283	Steven Hardiman	leave ope
75	Bug in STE fluxes	#1367	Fiona O'Connor	leave open. still not sure what is going on
87	Possible issues with YSTORE in UKCA_CHEMISTRY_CTL.	UM#3245	Colin Johnson/ Luke Abraham	leave open
92	UMDP084 incorrectly labels 38-476 ("Liquid cloud fraction") with units "m-3". It is a pure fraction (in the range 0.0 to 1.0) and so has no unit.

Depreciated code for future retirement

#	Description	Ticket	Remarks	Status	Owner
1	Deprecated UKCA netcdf attribute options	#2513	'emission_type', string type attributes no longer recommeneded. Need some time for most new code to adopt these	DEPRECATED	Nick Savage
2	Deprecated calculation of updraft velocity	#3668	'l_conv_tke', logical recommended true	DEPRECATED	Alan J Hewitt

 ==Actions from this meeting ==
-=== One off actions ===
-# (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.
-# (ongoing) LA to migrate PUMA UM tickets to MOSRS - see [[Minutes_of_the_code_management_group_meeting_2017-07-14#UKCA_Tickets_from_PUMA_UKCA_trac_pages_.28LA.29|table below]].
-# (ongoing) LA to open tickets for all changes that still require a ticket.
-# (ongoing) FOC to open ticket + Bugfixes Table entry related to 'Unable to calculate tropopause' warnings.
-# (ongoing) FOC to recommend at next Exec meeting a policy of allowing only CMG to (certify and) distribute any UKCA configurations for science purpose.
-# (ongoing) LA (& others who are interested) to look into how to re-organise the UKCA panel (e.g. into sub-panels) & think about removal of namelist items.
-# (ongoing) LA to organise a follow-up meeting of interested parties on the UKCA panel re-organisation.
-# (ongoing) MD to collate all UKCA parameters into <code>ukca_constants</code> in advance of removing duplicates already available in the UM and circulate details.
-# (ongoing) JM to continue discussions with CJ regarding ''"Wet oxidation of SO2 in GLOMAP"'' and other issues regarding redundant code.
-# (ongoing) AH to scope out reducing repetition of mode definitions in GLOMAP.
-# (ongoing) MD to set up TS2000 nudged jobs at vn10.8.
-# (ongoing) LA to add UKCA wiki page on using UKCA on the Virtual Machine.
-# (new) LA to embolden all ALL actions in future meetings
-# (new) FOC to arrange meeting between FOC, MR, MS, LA (& others who are interested) to sit down and decide a plan to move forward with OpenMP work, before new person starts.
-# (new) LA to update [[Redundant code]] tables with above information
-# (new) LA and MD to talk offline about releases.
-# (new) LA to look into recording lectures at January 2018 training
-# (new) LA to set-up doodle poll for sometime between 9th-28th February 2018.
-=== Standing actions ===
-# (ongoing - standing item) '''CMG''' to monitor list of bugs and circulate between group for owners.
-# (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).
-# (ongoing - standing item) '''ALL''' with access to keep monitoring ukca_bugs email list.
-# (ongoing - standing item) '''ALL''' to think about if code changes will change KGO and let systems team know in good time, and remember to include the UKCA & SC0138 keywords to all UKCA tickets. This should be a standard part of our working practice.
-# (ongoing - standing item) '''ALL''' to note, review, and remove obsolete/redundant code'''
-# (ongoing - standing item) '''ALL''' closed ticket owners to produce a summary of their change for the UKCA newsletter
-# (ongoing - standing item) '''Code Owner''' to produce draft newsletter for '''CMG''' to approve.
