Tickets (NLA)
Tickets on MOSRS:
PLEASE REMEMBER TO USE THE UKCA KEYWORD FOR ALL UKCA CHANGES THIS RELEASE
Also see overview ticket um:#7094
NOTE: The UM requirement for LFric testing
of all changes under UM:src/atmosphere, UKCA:src/science, and UKCA:src/control/core
Please also give any feedback on the UMvn13.2 release cycle to NLA to pass-back to UM Sys.
Message from UM Sys - please take care when considering keywords. It is important to get these correct for the Code Review process.
AJH ticket ukca:#7/um:#6630 will clash with everything - will ask to do last.
Difficulties with LFRic cycle, versioning, and when they release.
AJH will work out clashes on Code Review day.
Update on UKCA API redesign (JH)
JH - current improves interface for non-UM builds. Turning deposition & lumping on & off, reducing the number of input fields. Have also revamped the diagnostic output debugging input fields, now covers all required input fields. Will do automatically without having to duplicate logic, and can change also change the timestep when you get the output, e.g. for fields with a diurnal cycle etc., or have issues later in the run. Should be able to do in the UM too. Next priority is to implement the diagnostic handling system outside of the UM (not individual diags, just top-level functionality).
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. | Updated testing coverage on Linux and can run 1x1 decomposition | |
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. See UKCA Box Model page |
||
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. UKCA removed from UM at UMvn13.0 - see UKCA repo |
||
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. Convection & plume scavenging has been done. AJH - some of this has been done or is in progress. |
|
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 | AJH highlighted that there have been some discussions about this - a few people interested in this (James Manners, AH, Ben Johnson, AJH). Have had someone looking to see if something could be changed to make it faster to make a trimmed-down version with less calculations for e.g. NWP. | ||
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) Aerosol Dry Deposition will be considered in the JULES context once the gas-phase changes have been committed. |
Completed for UM13.1 | |
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. Closed - see also UKESM:#841 for UKCA package ticket |
|
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 | Closed | |
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 | A quick win here is to reduce nwbins in namelist ( see um:#4740 ). Parked for now. |
There does not seem to be resource to look at this at present. | |
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 See also UKESM:#841 for UKCA package ticket |
|
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. See also UKESM:#841 for UKCA package ticket |
|
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). See also UKESM:#841 for UKCA package ticket |
Action: AJH to check over list and see which have been completed.
Action: NLA to follow up with JM about UKESM2 package testing.
Bugs/Bugfixes (NLA)
Open Bugs
# | Description | Ticket | Owner | Comments | Comments from this meeting |
---|---|---|---|---|---|
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 Tested it quickly - N2 is used from namelist but not obvious, but H2 needs further testing |
|
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. See if can be done for 12.3 Nice to do ASAP, but if just diagnostics might be able to do at a later time. |
|
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 May just linger. Should we take the broken ones out? MD has opened a ticket to see which ones fail and which ones work |
||
140 | Heaviside Function cannot have multiple level sets | um:#6816 | The Heaviside function needed to scale UKCA pressure-level diagnostics is valid only for a single set of pressure levels from Stash requests. If some Sec 51/52 diagnostics are requested on say 19 pressure-levels and the same/ different ones on 36 pressure-levels, the Heaviside field in output will be applicable to only one of these. May be able to request multiple Heaviside functions |
||
141 | The area variable used for units conversion of GLOMAP primary emission diagnostics (38-20X) is calculated erroneously in LAMs (or with rotated pole). | Fix is to use the surf_area variable used for other calculations. Impact on concerned diags in Global runs being assessed MD assessing impact. MD has a fix, calculates 3D and passes it via API |
|||
143 | Error in print statements from UKCA_TRACERS_COPY_FROM_UM | The final species listed in the diagnostic print statement seems to have very large concentrations (O(1E+08)) compared to others in the ppm-ppt range. Does not seem to affect model output. Reported by James Weber. | |||
144 | interchangeable use of specific humidity and water vapour mixing ratio | #6813 | UKCA includes calculations of relative humidity, clear-sky relative humidity and saturation vapour pressure. Relative humidity calculations should be based on water vapour mass mixing ratio but are in part based on specific humidity. Also, the calculation of saturation vapour pressure is derived from saturation mixing ratio but uses a formula for deriving SVP from saturation specific humidity. This interchangeable use of specific humidity (ratio for moist air) and mixing ratio (ratio for dry air) in existing configurations introduces small numerical errors in UM and LFRic model runs. These bugs were identified at UM version vn12.2 and have been highlighted by comments in code lodged with UM ticket #6660 (in ukca_main1-ukca_main1.F90 and atmos_ukca_humidity_mod.F90). All UKCA configurations are affected. | JH doesn’t think it’s complicated but not particularly trivial either. | |
145 | all_ntp not explicitly dimensioned in UKCA_MAIN | Possible fix here | all_ntp not being dimensioned explicitly in ukca_main1-ukca_main1.F90. Highlighted in NCAS CMS ticket https://cms-helpdesk.ncas.ac.uk/t/nested-ukca-suite-on-archer2/604 raised by Paul Field. Grenville Lister has found the cause and implemented a possible fix https://code.metoffice.gov.uk/trac/um/changeset/110132/main/branches/dev/grenvillelister/vn12.0_all_ntp_fix |
||
147 | Missing products in Sec-50 diagnostics: Mismatch in ukca_chem_master and asad_flux_dat 50-092 STRATOSPHERIC OH LOSS (B153) Products for (OH + H2) changed under scheme v121 but not reflected in asad_flux_dat 50-123 STRAT O3 LOSS: HO2 + NO3 (B61) Product O2 not available for StratTrop After chem v121/ always |

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 | ||
13 | Remove temporary logical l_fix_nacl_density Introduced at UM:#2405 |
UM:#3490 | Requires AMIP testing and a GMED ticket Could be accepted to GA9 |
PROPOSED | Medium-term | Jane Mulcahy | See JM GMED action | |
15 | Remove temporary logical l_fix_ukca_impscav Introduced at UM:#1421 |
UM:#4145 | Approval being sought for GA series (likely GA9) GMED:#402 |
PROPOSED | Medium-term | Alan J Hewitt | See JM GMED action | |
16 | Remove temporary logical l_fix_improve_drydep Introduced at UM:#1250 |
UM:#3997 | Approval being sought for GA series (likely GA9) GMED:#393 |
PROPOSED | Medium-term | Alan J Hewitt | See JM GMED action | |
17 | Remove temporary logical l_fix_ukca_h2dd_x Introduced at UM:#4157 |
UM:#4245 | Approval being sought for GA series (likely GA9) GMED:#410 |
PROPOSED | Medium-term | Alan J Hewitt | See JM GMED action | |
18 | Remove temporary logical l_fix_neg_pvol_wat Introduced at UM:#4383 |
UM:#4416 | Approval being sought for GA series (likely GA9) GMED:#421 |
PROPOSED | Medium-term | Alan J Hewitt | ||
21 | Remove code behind L_use_stratclim from ukca_fastjx_mod Introduced prior to MOSRS |
UM:#4854 | This could either be properly included via a namelist or removed from the UM | PROPOSED | Medium-term | Alan J Hewitt | LA contact OW about progressing FastJX-RADAER work Ties in with API work. MD/NC to take a look, can be removed. Do as part of API. Relevant person take ownership as part of API work NC to take ownership as part of his work |
|
22 | Remove temporary logical l_fix_ukca_input_meoh_emiss Introduced at UM:#3031 |
UM:#4848 | Approval being sought for GA series (likely GA9) GMED:#461 |
PROPOSED | Medium-term | Mohit Dalvi | ||
24 | Remove ability to use of Cambridge 2D model data from ukca_stratf.F90 | PROPOSED | Neal Carr | Need to confirm from wider community for possible tropospheric configs and other choices for top-bdy | ||||
25 | Change from using ukca_chem_master.F90 to a file-read for the chemical mechanism | PROPOSED | Short-term | Luke Abraham | Current chem_master module has compiler issues with that require changes to optimisation level on some compilers. A file read would be more flexible and would allow the mechanism to be more easily changed not requiring UM/UKCA code tickets. |
A lot of changes tied up with GA6/7. May be taking GA6 away soon. GA7 is tied to UKESM1, but should be able to remove once UKESM1.1 paper is published.
AJH may be able to remove 9 PFT option, but it might be better to do when removing other dry-dep temporary logicals.
