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, 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.
  5. (ongoing - standing item) ALL to note, review, and remove obsolete/redundant code
  6. (ongoing - standing item) ALL closed ticket owners to produce a summary of their change for the UKCA newsletter
  7. (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 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 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
