Bugs/Bugfixes (NLA)
Open Bugs
# | Description | Ticket | Owner | Comments | Comments from this meeting |
---|---|---|---|---|---|
35 | Error in labelling: Surface resistance <--> stomatal resistance ? | UM:#1409 | Fiona O'Connor | Leave open. Garry Hayman started work in offline JULES. Still ongoing. JM found bug in SO2 deposition, where there is an inconsistency when changing tiles. Making progress. Leave open. GH gave update, has done a lot of work. Concerned it might not be bit-reproducable, but could be solvable. Encouraging to lodge existing. Resistances done as metadata. Not clear as to timescales. FOC to encourage Garry Hayman to start lodging JULES code piecemeal. LA to email GH, cc JM JM to email GH GH adding improvements via UM:#5751 |
|
101 | Errors in reaction rates and diagnostics | UM:#4466 | Luke Abraham / Scott Archer-Nicolls | There is a need to conserve science config for UKESM1, so changes need to be on a flag. Colin has been looking at DMSO, as this is not currently used in StratTrop but is in Offline. Might be able to merge the rate with CEJ changes, but best to leave the diagnostic issues as a separate change. LA, JM, CEJ, SAN to discuss offline and keep GM in loop. Use versioning system. Talk about further offline. Keep ongoing. LA to do with #103 Do for vn11.6. Quite a large ticket. Hope to progress for vn11.6 Bump for vn11.7 LA may be able to progress. Versioning has been done separately. Another issue was added to this recently, to do with formation of H2O - may have an impact Some CRI fixes needed too. May not be able to progress for vn11.7 Some of the fixes have been incorporated in UM:#5057 #5057 didn’t make vn11.8 Will aim for vn12.1, also updates from JMK |
|
109 | Bug in dry deposition of CH4 for 13/17/27 tiles | UM:#5919 | Gerd Folberth | To be Lodged after 10.6 Gerd noted unusual CH4 output in CMIP6 runs. May need a rose stem test for H2 and CH4 drdydep code lodged at UM:#4157 Makes a huge difference to CH4. Needs testing. AJH or GF will do during vn11.4, progress for vn11.6. May need UKESM1 approval. Code is difficult to understand. AJH thinks GarryH is aware of this problem. LA to ask GF to add more details GF has emailed. LA to update wiki pages (see below) Only impacts emission driven runs. LA to check with Gerd about this issue NLA to chase GF NC to keep on top of GF. NC will be S/T, GF is still thinking about it. |
Should be fixed in his ticket |
110 | UKCA solar-cycle routine does not pass NRUN-CRUN test | UM:#4828 | Luke Abraham | To be Lodged after 11.5 Have a solution. Solution is a bit tricky to check the logic correctly. Currently testing. May not make vn11.7. Will not make UMvn11.7 - need to analyse runs to understand what is going on NLA to investigate further NLA to chat with OM offline LA & OM will talk offline |
|
119 | Incorrect calculation for gridbox area - only affects GLOMAP-mode diagnostics | um:#5506 | Calculation of volume appears correct, but area is not. This calculation is missing the factor fv_cos_theta_latitude so will not cause area to tend towards zero at the poles. It also seems to use an unnecessary approximation to the latitude difference (based on sinv_latitude ) which may break down at high latitudes. The calculation should perhaps be consistent with subsequent volume calculation but without the delta_r factor. This will likely only affect diagnostics calculated in ukca_emiss_diags_mode , where it is used to convert from kg/m2/s to mol/gridbox/s, although it is also printed out in ukca_aero_ctl . JH spotted. Just diagnostic affected. LA to open a ticket. cc JM, NC LA to update with MOSRS ticket No owner yet Needs testing. GM will have a look, but can’t take it on As its just diagnostic, may not be that important for UKESM2 |
||
124 | H2 and N2 cannot be set for RCP and WMOA1 scenario routines | UM:#5620 | Mohit Dalvi | Values are hard-wired in the code and cannot be changed without a branch Will be handled at UM11.8 At least for the next version |
Keep open |
128 | Bug in UKCA stratospheric chemistry diagnostics | UM:#5839 | Luke Abraham | pre-UMvn10.0. The indexing/values of diagnostics m01s50i101-i104 are incorrect. Fixes provided for vn11.1 and vn11.7. May affect CMIP6 diagnostics May be best to lump #101. NLA to contact JM |
Should be fixed for UKESM2 |
130 | Bug in aerosol dry deposition when using 27 surface types in JULES | UM:#6088 Partially fixed using UM:#5622 |
Mohit Dalvi | The bug exists because of an erroneous dependency on the array size NTYPE (from JULES_SURFACE_TYPES_MOD) in subroutines UKCA_DDEPAER and UKCA_DDEPAER_INCL_SEDI. This is not appropriate because most of the processing is not written to be dependent on the surface types being used in JULES. A surface type at each location is instead inferred (in UKCA_AERO_CTL) from the roughness length and its index is held in the array ILSCAT. The index values are intended to be interpreted with reference to the JULES 9 type scheme. Only the values 1, 3, 7 and 9 are used, corresponding to forest, grassland, water and ice respectively. The indices are used to access arrays YR, CR and ALPHA that are set up in these aerosol dry deposition routines. The arrays should therefore always be of size 9 with values based on the 9 type scheme, irrespective of the JULES NTYPE value. However, alternative, incompatible arrays are set up if NTYPE is 13, 17 or 27. These were presumably intended to be accessed using the type indices consistent with the other JULES schemes but are actually accessed with the 9-type scheme indices available in ILSCAT. Inappropriate values will therefore be obtained when NTYPE is not 9. Note that Ticket UM:#5622 will fix the bug when interactive dry deposition is not used in the chemistry or when NTYPE in JULES is 13 or 17 but will not fix it when interactive dry deposition is selected (L_UKCA_INTDD = .TRUE.) and NTYPE is 27. Fixing it for NTYPE = 27 will change results so will require a separate bug fix ticket with appropriate testing and approval. Fix is simple (~1-line) but testing will take time. Does affect UKESM1 - anything that doesn’t have 9 surface types. CH to pass on to JM. Ticket opened. MD to take ownership Had a discussion with Graham and Samuel Remy regarding implemention of the scheme in IFS. Work likely to start later in May. |
Simple method (predominant surface type) for mapping from JULES being tested. Will have to determine how to handle pseudo-levels/ ntypes in the segments/chunking before deriving rates for multiple surface types. Discuss with MR/MG. |
131 | Invalid surface roughness input to aerosol dry deposition over land | UM:#6088 | Mohit Dalvi | In the UM, UKCA uses the roughness length with stash code 00026 to infer the surface type for aerosol dry deposition (and for the old non-interactive gas dry deposition scheme). However, this value is only valid over the sea. It seems to be set to 0.5 over the land from the UM data I’ve looked at. This seems to be simply a filler value with no scientific significance. As a consequence of the 0.5 value, the UKCA aerosol dry deposition routines categorise all land as forest in the UM runs (routine ukca_aero_ctl uses z0>0.1m for forest). This will interact with bug #130 in aerosol dry deposition (see above) that occurs when using any number of surface types in JULES other than 9. In LFRic JH is using the tile values. Not sure how easy this would be to do in the UM. Could be out of scope for this group - potentially ask Adrian Lock or Ian Boutle. NLA to email. Found e-mail from Ian/Adrian (Feb:2016) suggesting 3-028 instead. Ticket opened. MD to take ownership. See #130 above. |
Exploring the use of type/tile-based surface roughness from JULES, to avoid retrospective stash changes to (GA/GC/UKCA//UKESM) suites. |
Redundant Code (NLA)
Code for deletion
PLEASE REMEMBER TO EDIT THE ORIGINAL REDUNDANT CODE TABLE AND NOT THIS PAGE
- The NG-Composition Project Board has agreed to use the Redundant code table as the Technical Debt Log for UKCA as part of that project. This has highlighted the issue that some areas of code are not listed as being redundant, but are also not tested/used routinely and are not in any rose-stem tests, for example 2D photolysis and the TropIsop and Strat chemistry schemes. We have been asked to review this code and list untested code which is still desirable to be included for testing, and to ensure that other areas of code are listed for deletion.
# | Description | Ticket | Remarks | Status | Timeframe | Owner | Comments from previous meetings | Comments from this meeting |
---|---|---|---|---|---|---|---|---|
4 | ukca_strat_update.F90 - relax_ozone | UM:#1505 | None | PROPOSED | Medium-term | Luke Abraham | ||
5 | Backward Euler Standard Tropospheric Chemistry | UM:#1507 | None | PROPOSED | Medium-term | Fiona O'Connor | ||
6 | Wet oxidation of SO2 in GLOMAP | UM:#4475 | None | PROPOSED | Medium-term | Colin Johnson | JM to look at this re: UKESM1 c.f. offline GLOMAP. JM to take ownership. Still needed for CTM. Relevance for standalone code and later coupling to CTM. |
|
7 | Updraft velocity - l_conv_tke | UM:#3668 | Proposed in December 2017. Approval being sought for GA series (likely GA8). | PROPOSED | Medium-term | Alan J Hewitt / Ian Boutle | ||
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 | UM:#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. Have gone from operational jobs, have ticket to remove from rose-stem. LN to document. These have been removed from AQUM. AQUM work has been done. From AS: In the ancil ticket linked from #2513 (https://code.metoffice.gov.uk/trac/ancil/ticket/782) it says that GA7 depends on the old format files, and as far as I know this is still true. In the 3-step timeline suggested, we haven't reached step 2 unfortunately. That ticket was about ensuring GA8 did not use the old attributes. I believe that GA8 is due for release in the next few months (it has been a very long time coming), so UM vn11.5 may be the last version at which GA7 is supported. Do you mind waiting a bit longer? AJH to follow-up with LA |
|
10 | ASAD families chemistry | None | Families chemistry has not been used for many years (since at least UM6.1. It is likely that it no longer works if turned on, and it complicates the code making other developments harder | DEPRECATED | Short-term | Luke Abraham | ||
11 | Dry deposition 9 PFT option | None | The 13 PFT option has been adopted for UKESM1. The 9 PFT option is possibly not being used at all. Proposed in June 2018. |
PROPOSED | Long-term | Alan J Hewitt | ||
12 | Remove explicit C_SPECIES constants and calculate these from M_SPECIES and the mass of air |
None | Will have wide-ranging rose-stem KGO breakages | PROPOSED | Short-term | Luke Abraham | ||

Update on UKCA API redesign
Please see the document UKCA_API_design_proposal_v5.pdf for the latest API design.
2D photolysis has been done, NC now moving on to moving the photolysis routines before the main call to UKCA.
UKCA box model is "technically" working.
Progress with Priorities (NLA)
ACTION REQUEST FROM UKCA SCIENCE & MANAGEMENT BOARD: CMG to provide list of priorities & their status, with particular thought to UKESM2 changes that will be required.
GM asked about the UKCA science meeting and whether there would there be a community session? GF might be best person to ask this question.
The current priorities are:
# | Description | Owner | Desirable for UKESM2? | Status |
---|---|---|---|---|
1 | UKCA API | John Hemmings (main) | No | UKCA API work is progressing (AJH). Radaer API on hold until after GA7 port to LFRic. Functionality of RADAER in LFRic will work without an API although it will be preferable to update this in future. |
2 | Review UKCA tests to cover all requirements | Luke Abraham / Mohit Dalvi | Will cover these in a table in future for review. | |
3 | Updates/fixes to GLOMAP routines | YES | ||
4 | Standalone UKCA configurations | Luke Abraham/Scott Archer-Nicholls | ExCALIBUR work progressing, currently working on build system. | |
5 | Emissions flexibility | Mohit Dalvi | ||
6 | Separare UKCA repository | Luke Abraham | Separate UKCA trac environment set-up on MOSRS here, will hold UKCA code on completion of current ExCALIBUR project. | |
7 | Non-API LFRic work, e.g. Porting science functionality etc. | Alan J Hewitt | No | Porting calculation of CDNC from GLOMAP Climatology aerosols complete. I will pass required elements of ukca_radaer to ukca_radaer_band_average (um:#5957) Porting calculation of fields in radaer_band_average to be passed to Socrates underway(lfric:#2488) Includes RADAER, need to use imode_setup=8 RADAER now callable from LFRic, can do GA-type comparisons from LFRic to UM. JH to put UKCA into LFRic soon - working in an SCM configuration (GLOMAP with offox) - needs more testing. A lot more work to do, possibly until end of 2021. |
8 | RADAER API | Alan Hewitt (main) | No | Radaer API on hold until after GA7 port to LFRic. Functionality of RADAER in LFRic will work without an API although it will be preferable to update this in future. Not clear if RADAER will work independently of UM in single column mode. AJH and AH and JH and Ben Johnson and NB need to work out if desirable and practical to run independent of UM. |
9 | RADAER optimisation | NO | ||
10 | Dry deposition and Jules tiles | YES | If Jules adds extra tiles for UKESM2 we may need to hard code options in dry deposition (like in um:#1761) | |
11 | FastJX-GLOMAP coupling | YES | UMvn10.8 branches exist - see ticket UM:#2689 Note: FastJX rates also need updating - potential for code as well as input-file changes | |
12 | Cloud-J | |||
13 | Fixes for chemistry rates and ASAD (bugs #101 & #103) | Luke Abraham | YES | #101 still open, #103 completed (necessary for GC5 ticket GMED:#551) |
14 | Rc fixes for water (bug #104) | UKESM Core Team | YES | Lodged at UMvn11.7 in ticket UM:#5167 |
15 | CH4 deposition fixes (bug #109) | Gerd Folberth | YES | |
16 | UKCA STASHmaster PP-codes | Luke Abraham | Verification system makes some use of existing PP-codes. New items should have a PP-code of 0 and verification team will use STASH items for these if required. | |
17 | Removal of redundant code | ALL | No | Parked whilst GA7.0 is a protected suite. |
18 | GLOMAP-CLIM API refresh | Alan J Hewitt | No | Parked until science functionality around GLOMAP aerosols ported to LFRic. |
19 | N48L85 configuration | |||
20 | ACTIVATE optimisation | TBC | No | A quick win here is to reduce nwbins in namelist ( see um:#4740 ). Parked for now. |
21 | Stratospheric Ozone improvements | James Keeble/Luke Abraham | YES | Work ongoing, covered in ticket UM:#5641. Note: FastJX rates also need updating - potential for code as well as input-file changes |
22 | Solar cycle in photolysis | Luke Abraham | YES | Some code lodged at UMvn10.9 (UM:#2587) but needs bugfixing. This work has stalled in ticket UM:#4828 (bug #110). |
23 | Deposition updates from CSIRO | YES | Code lodged in UM:#4020 (UMvn11.4, oceanic dry deposition) and UM:#5713 (UMvn11.8, Lightning NOx updates). |
Tickets
See here for UM vn12.0 tickets on MOSRS.
See here for UM vn12.1 tickets on MOSRS.
PLEASE REMEMBER TO USE THE UKCA KEYWORD FOR ALL UKCA CHANGES
NOTE: New requirement for LFric testing
of all changes under src/atmosphere
There were a number of difficulties this release:
- um:#6135 had several issues with STASH that weren't found in usual rose-stem testing
- um:#5921 had the wrong revision initially committed to the trunk.
- um:#5813 had the wrong revision initially committed to the trunk.
- um:#6151 initially didn't have the Docs committed.
AJH had chat about potential clashes, knew some needed HoT branches. Overall what we did was quite good, as there could have been more problems.
The UM Systems Team will have follow-up meeting and it will be discussed at the UM-DOG.
12.1 tickets
GM noted that there are core GLOMAP tickets still to go in and has been in touch with AJH about this. Andy Jones will review.
