Actions from this meeting
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.

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. Garry Hayman started work in offline JULES | |||
| 72 | UKCA Dry Deposition: Surface resistance values not set for some species |
#1250 | AlanJHewitt | AH working on this. Thinks Monoterp flags should be turned off. Now has surface resistance values for all species, although including these will have knock-on effects and there is some some nasty buggy/code. Current target is vn11.1, although will break KGO and a proper assessment will need to be done. Will chase further particulars offline. GF to take a look. | |||
| 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. |
FOC to update comments. Scope has been extend. | ||
| 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 |
Leave open. Still not sure if ENDGame related or not. | ||
| 87 | Possible issues with YSTORE in UKCA_CHEMISTRY_CTL. | UM#3245 | Colin Johnson/ Luke Abraham |
leave open LA to talk to CJ offline. |
leave open. | ||
| 94 | Data corruption in Age-of-Air (and possibly Passive O3) diagnostic on pressure levels | UM#3718 | Mohit Dalvi | To be lodged at vn11.1. See um:#3718. | |||
| 96 | Output drydiam diagnostics where l_ukca_arg_act but not l_ukca_radaer | UM#3962 | Unknown | The beginnings of a solution are found in vn11.0_ukca_drydiam_activate_wo_radaer. |
Redundant Code (LA)
Code for deletion
| # | Description | Ticket | Remarks | Status | Timeframe | Owner | Comments from this meeting |
|---|---|---|---|---|---|---|---|
| 2 | Old dry deposition scheme | #2356 | None | PROPOSED | Medium-term | Nick Savage | |
| 4 | ukca_strat_update.F90 - relax_ozone | #1505 | None | PROPOSED | Medium-term | Luke Abraham | |
| 5 | Backward Euler Standard Tropospheric Chemistry | #1507 | None | PROPOSED | Medium-term | Fiona O'Connor | |
| 6 | Wet oxidation of SO2 in GLOMAP | None | None | PROPOSED | Medium-term | Colin Johnson | |
| 7 | Updraft velocity | #3668 | Proposed in December 2017 | PROPOSED | Medium-term | Alan J Hewitt | |
| 8 | All backward Euler chemistry schemes | None | 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 that problems for AQUM would need to be addressed first. | PROPOSED | Long-term | Luke Abraham | |
| 9 | Deprecated UKCA netcdf attribute options | #2513 | 'emission_type', string type attributes no longer recommeneded. Need some time for most new code to adopt these. Still used in AQUM files. | DEPRECATED | Medium-term | Nick Savage | AQUM are addressing the files. |
New Action: LA to add families chemistry to the Redundant code table, with a short- or medium-term target (possibly even vn11.2).
