Tickets (NLA)
See here for UM vn12.2 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
Please also give any feedback on the UMvn12.2 release cycle to NLA to pass-back to UM Sys.
JH will attend UM DOG at next meeting. NLA has also been invited to attend UM Interfaces Group (AH also a member).
JULES dry-deposition ticket has failed. CH will push for vn12.3 and will speak to Garry & Phil, and there is a meeting on Thursday to discuss the change. Monsoon testing is tricky and the code is still being debugged.
This cycle was tricky as it is a short cycle due to Christmas and releases have gotten later.
It is now really tricky to get joint UM-LFRic tickets in due to not having a synced release cycle.
MS had issues with s51 pressure-level code.
ACTION: MS to cc s51 issues ticket with AH
Update on UKCA API redesign (JH)
Please see the document UKCA_API_design_proposal_v5.pdf for the latest API design and UKCA_Modules_at_UMvn12.0.pdf for the latest categorisation of UKCA files.
Major thing from the UMvn12.2 release is the photolysis interface by NC, so that is on the UM side of the API. No internal photolysis from the next release. Note that headers need to be updated to be UKCA_UM section, as well as a few other things.
For the UMvn12.3 release:
- Add some new functionality to support NAME/box model, e.g. switches so things can be turned on/off such as dry deposition, the tracer lumping & unlumping (SAN has put in switch for emissions). This means parent will have more control to avoid passing dummy variables.
- Avoid calling UM modules/dependencies where possible, or encapsulate them in a legacy module. Then there will be a UM version of that & a UKCA dummy version of that. The parent routines (e.g. TR_MIX, TRSRCE, QSAT) will either be duplicated on UKCA side, or available via a call-back routine.
- Constant modules should have it’s own values available to be over-ruled by the parent.
Note that the (current!) major science changes for vn12.3 are JULES dry deposition & the GLOMAP updates. There is potential for conflicts and the GLOMAP changes could be in breach of the design document. The API changes made need to be done as a HoT branch towards the end of the release cycle.
UKCA Developments over 2022 (NLA)
Due to the progress with the work for ExCALIBUR and the upcoming fork of physics for LFRic, we are aiming to extract UKCA from the UM and into its own repository (https://code.metoffice.gov.uk/trac/ukca) for the UMvn12.3 release.
The current aim is to extract UKCA out for vn12.3 (in line with LFRic fork). For this we will also need a box-model rose-stem test.
Nigel Wood has a person from ExCALIBUR to work on the technical aspects regarding linking from the new repository, but this may not be until later in the summer.
ACTION: NLA to arrange meeting with UMSys about the UKCA repository work, including AH.
The JULES dry-deposition work was also discussed in relation to the CSIRO work, in particular because the configuration there uses CABLE rather than JULES.
It was decided that moving forward these meetings should cover LFRic, NAME, & the Box Model as well as the UM. Items and issues related to the other (non-UM) models will ramp up over time. We will have more shared interests moving forward.
ACTION: NLA to include LFRic, NAME, and Box Model tickets (where they exist) under discussion item for the agenda moving forward.
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.
The current priorities are:
# | Description | Owner | Desirable for UKESM2? | Status | Comments from this meeting |
---|---|---|---|---|---|
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 | AH asked about the stratospheric changes from a UKESM2 context, and whether there is any help for these. | ||
4 | Standalone UKCA configurations | Luke Abraham/Scott Archer-Nicholls | ExCALIBUR work progressing. | Aim to remove UKCA from UM trunk at vn12.3. | |
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. | Aiming for vn12.3. | |
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. AJH has tickets going in for 12.1 that would cover all of the basic GA7 but with climatological aerosol. JH tickets will do the prognostic alternative. JH currently has an LFRic-SCM configuration with prognostic aerosol. |
JH now has UKCA working in proto-GAL7 (LFRic) config. Needs to couple with convection & plume scavenging. |
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) | Issues on EX1A. |
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 UKESM:#729 |
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 UKESM:#732 |
Some code lodged at UMvn10.9 (UM:#2587) but needs bugfixing. This work has stalled in ticket UM:#4828 (bug #110). | UM:#4828 lodged for UMvn12.2. |
23 | Deposition updates from CSIRO | YES UKESM:#730 UKESM:#739 |
Code lodged in UM:#4020 (UMvn11.4, oceanic dry deposition) and UM:#5713 (UMvn11.8, Lightning NOx updates). |
AH highlighted that AJ has been working on GLOMAP-dust. CASIM work is also continuing in relation to the RA3 project where the testing has been good and the next step is coupling to UKCA. AJH - working on functionality of interactive dust with GLOMAP-CLIM (LFRic only)
Bugs/Bugfixes (NLA)
Open Bugs
# | Description | Ticket | Owner | Comments | Comments from this meeting |
---|---|---|---|---|---|
35 | Error in labelling: Surface resistance <--> stomatal resistance ? | UM:#1409 um:#5751 |
Fiona O'Connor/Garry Hayman | 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 GH targeting 12.2 |
um:#5751 was in code review for UMvn12.2 but failed to progress - aiming for early in vn12.3 release cycle. |
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 |
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 Biggish ticket for 12.2 with bug fixes. |
|
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. Implemented a flexible method to determine dominant surface type and use roughness length specific to that tile. Simulations for 20/30 years with GA8 and UKESM1.1 ; results passed on to GMED and UKESM for assessing impact. Also being tested with DM-Chem (Delhi model) for newly added urban sub-tiles. Aiming for vn12.2 |
In code review for vn12.2 |
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. Using tile-specific roughness lengths as obtained from JULES Part of above change for vn12.2 |
In code review for vn12.2 |
135 | The SO2 dry deposition improvements added under #5167 do not work for Convection permitting configurations (e.g Nested suite) and fail due to absence of Convection diagnostics. | um:#6433 | The error message could be turned to a warning and related fields initialised to zero | ||
136 | There appears to be a bug in some Section 51 diagnostics. | 6598 | 51996 and 51999 are fine. 51921 and 51922 are broken. Other fields unknown. Problem uncovered during 6358 |
||
138 | Missing dry deposition settings in ukca_aerod for RA13NO3, RA16NO3 and RA19NO3 for CRI-Strat v2. | um:#6626 | Discovered in um:#5751. | ||
139 | Several rose-stem failures on the new EX1A HPC | um:#6610 | Also impacts use of gmed:#551. | This has LFRic impacts, but LFRic are currently testing with GAL7. At GAL9, could cause significiant issues. ACTION: MD to take a look at EX1A issues (um:#6610). NLA to cc MD into email from Rich Gilham. |
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. |
