Actions from this meeting
Minutes
Actions from the Last Meeting (LA)
Minutes of the code management group meeting 2018-02-21
One off actions
- (ongoing) GM find best person 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.
- (new) LA to follow-up with GM in 2 weeks time to progress this.
- (ongoing) LA to migrate PUMA UM tickets to MOSRS - see 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, which will also address print statements.
- (new) FOC to open ticket to add flexibility to use the s30 tropopause.
- (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
ukca_constants
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. GM to be kept informed.
- (ongoing) AH to scope out reducing repetition of mode definitions in GLOMAP.
- (new) FOC to upload workplan.
- (ongoing) LA and MD to talk offline about releases.
- (new) FOC to check with AS about best practice when science changes break KGO.
- (new) MD to correct column-call rose-stem tests when pressure-level age-of-air diagnostic bugfix is lodged.
- (new) LA to comment code regarding wet deposition of ozone inconsistencies.
- (new) LA to update open bugs table.
- (new) LA to re-jig tables as short-term and long-term plans.
- (new) MD/LA to set up free-running and nudged GA7.1+StratTrop TS2000ish timeslice, with instructions to make it transient.
- (new) LA to create Wiki page on UKCA website for users to add details of configurations and input files.
- (new) LA to set up doodle-poll for the 2nd/3rd week of June, avoiding various meetings going on then.
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. Note also the required keywords.
- (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.
One off actions
Bugs/Bugfixes (LA)
Open Bugs
# | Description | Ticket | Owner | Status/ Updates | Comments from previous meeting | Comments from this meeting |
---|---|---|---|---|---|---|
35 | Error in labelling: Surface resistance <--> stomatal resistance ? | MOSRS #1409 | Fiona O'Connor | Leave open for planned JULES work. | ||
57 | Incorrect logic for DMS anciliaries required | #756 (MOSRS) | Nick Savage | Possibly close: JM to check impact. LA/SAN to contact JM |
||
72 | UKCA Dry Deposition: Surface resistance values not set for some species |
#1250 | AlanJHewitt | leave open AH investigating best way forward and will speak with JM. Some concern regarding breaking UKESM1 KGO. See action. |
||
74 | Bug in ukca_tropopause with definition of PV tropopause | #1283 | Fiona O'Connor | leave open Change ownership to FOC. Extend scope for print statements. |
||
75 | Bug in STE fluxes | #1367 | Fiona O'Connor | leave open. still not sure what is going on Believed to be ENDGAME related. Will investigate following the release of UKESM1 |
||
87 | Possible issues with YSTORE in UKCA_CHEMISTRY_CTL. | UM#3245 | Colin Johnson/ Luke Abraham |
leave open LA to talk to CJ offline. |
||
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. | Alan Hewitt | AH to take ownership. | |||
93 | Inconsistent surface resistance values for organic hydro-peroxide (rooh) | UM#3793 | Alan Hewitt | AH to take ownership and talk to GF | ||
94 | Data corruption in Age-of-Air (and possibly Passive O3) diagnostic on pressure levels | UM#3718 | Mohit Dalvi | Found to be a halo issue in STASHmaster_A. Hope to close soon. Will also correct column-call rose-stem tests. |
Redundant Code (LA)
Code for deletion
# | Description | Ticket | Remarks | Status | Owner | Comments from this meeting |
---|---|---|---|---|---|---|
2 | Old dry deposition scheme | #2356 | None | PROPOSED | Nick Savage | Leave as-is |
4 | ukca_strat_update.F90 - relax_ozone | #1505 | None | PROPOSED | Nick Savage | LA to take ownership |
5 | Backward Euler Standard Tropospheric Chemistry | #1507 | None | PROPOSED | Nick Savage | FOC to take ownership |
6 | Wet oxidation of SO2 in GLOMAP | None | None | PROPOSED | Colin Johnson | CJ/JM to discuss with GM |
7 | Updraft velocity | #3668 | Proposed in December 2017 | PROPOSED | Alan J Hewitt | AH to investigate further |
8 | All backward Euler chemistry schemes | None | None | PROPOSED | Luke Abraham | Note that this is only for the “hard-coded” BE schemes. Quite a lot of work would be involved, but good as a longer-term aim. Note problems for AQUM would need to be addressed first. |
Depreciated code for future retirement
# | Description | Ticket | Remarks | Status | Owner | Comments from this meeting |
---|---|---|---|---|---|---|
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 | Not yet due to AQUM files |
2 | Deprecated calculation of updraft velocity | #3668 | 'l_conv_tke', logical recommended true | DEPRECATED | Alan J Hewitt | Remove as a duplicate of 7 above. |
Action: LA to re-jig tables as short-term and long-term plans.
Note that GLOMAP changes should be discussed with Leeds.
