UKCA Code Management Meeting, 12 February 2013 (tele-conference).
Participants:
Met Office: Nick Savage (NS), Colin Johnson (CJ), Mohit Dalvi (MD)
Cambridge: Alex Archibald (AA), Luke Abraham (LA)
Leeds: Graham Mann (GM)
Oxford: Zak Kipling (ZK)
Summary of action points arising in the meeting
- MD to circulate details on 1st version of Evaluation suite.
- GM to look into possible numerical errors in latest UKCA-Achem-MODE job.
- MD/CJ to port across a UM8.3 StratTrop+Achem+MODE job to MONSooN.
- LA/AA to suggest parameters for evaluating ENDGAME+UKCA configuration.
- NS to brief LA on status and required UKCA changes for Rose.
- LA/GM to finalise vn8.x MODE configuration for upcoming UKCA tutorial.
- NS/LA/AA/Fiona to decide regarding updation of reaction rates for TropIsop,Strat schemes.
- CMG to discuss with Project Board regarding follow-up meeting during March NCAS Meeting.
Carried forward from previous meetings
- Dust: CJ has got 2-MODE dust scheme working. Stephanie evaluating results.
- Nitrate : SteveR's job+branch working. CJ to check whether nitrate is turned ON.
Other discussions
- MD briefed that a version of the Evaluation package, based on Fiona/NIWA/Alex's scripts is available on Postproc. Alex inquired whether a 'tile plot/ signal plot' type of multi-model/ multi-parameter interpretation is possible. This will be taken up in the next phase.
- NS briefed on status of vn8.2/3 AQUM job on MONSooN. LA asked whether this was easily configurable for users. NS replied this can be looked into if there was sufficient demand, but will require dedicated resource to maintain.
- Status of
- NS: Little progress on tracer rationalisation, but a better understanding of the current situation. We'll need a new tracer for sodium, and to clarify the sea salt tracer, before nitrate goes in.
- NS: Fiona has tested new reaction rates in CheST @ 8.2, but what do we do about CheS and CheT (where the new rates have only been tested at 7.3)? Not enough resources to test these @ 8.2 at present. It would be good if rates were switchable, but not possible yet. Decision: Only update CheST for HadGEM3 ESM1, but prioritise testing CheS/CheT in the new year.
- Steve is teting the nitrate code. GM to discuss this with him. However, this is no longer slated for 8.4, but will be in 9.0 (which was previously to be called 8.6).
- MD: Evaluation suite code is on
postproc03, but still being tied together - MD: Currently checking tracer transport in UKCA with ENDGAME. Refer to experience with CLASSIC tracers.
- CJ: Nucleation-scavenging timescale in 8.2 longer for SU/SS, but shorter for OC, compared to 7.3. Large-scale now looks good, but convective problematic. Will try to merge ZK's code in Jan. GM to look at tuning the existing scheme.
- CJ: Currently trying to get a 2-mode dust-only scheme working – problems in
UKCA_EMISSION_CTLdue to dependencies on chemistry. - CJ: offline oxidant configuration giving reasonable results, may lodge in January if time. Still not that fast (with N-R solver), so need to try different solvers (B-E, KPP).
Outlook (NS)
- ROSE progressing well.
- 8.4 frozen end Jan.
- 8.5 closed to bring in ROSE support (UMUI still supported too at this point).
- 9.0 first ROSE-only release, will also include science changes.
- ROSE will be used operationally by September.
- Richard Barnes has the ticket for UKCA ROSE support, but will need help from the rest of us to understand the current control logic.
Date of Next meeting
Mid-January, NS to setup doodle poll (http://www.doodle.com/8aacaepan75mrugr).
