Occurring on Zoom, Monday 11:30-12:30 every 2 weeks, offset from the 21st Century Weather ModSci meetings, starting Monday 1 September.
Suggested items for today’s meeting (cross-posting from Cumulus):
-
Recap decisions made in the NRI meeting last week (Julie and Li?)
-
Working practice recommendations (Pao)
Anything else we need to cover today?
Hi all, given that tomorrow is a public holiday in VIC, can I ask for any suggested agenda items for Monday’s meeting?
Cross-posting from Cumulus with the agenda for our next meeting (Monday 13 October):
-
summary of the bugs & bug fixes uncovered (@m.lipson to lead)
-
workflow moving forward (@paocorrales to lead)
-
optimisation (@paocorrales )
UPDATE: Thanks to the excellent collaboration between 21st Century Weather and the ACCESS NRI, we now have a working N512 version of ACCESS AM3.

Minutes from 10 November meeting:
Github & Hive updates (Lachlan):
- ACCESS NRI private repositories are now able to be forked to 21st Century Weather which allows them to be pushed back too
- Rename the high-res AM3 category on the Hive Forum as “AM3” and use a “high-res AM3” label
Final steps towards running a longer experiment
- NCMAS application submitted to perform the highresSST-present experiment at N512 resolution. Asked for 15 kSU per month = 7740 kSU for 43 years, will find out on 6 Jan. Either way we want to have a final version tested to start running experiments in Q1 2026
- Land surface ancillaries
- Mat: would be good to test higher resolution land ancillaries as a base e.g. using CCI as a starting point rather than current 0.5 deg dataset. Lachlan: currently implementing the use of the CCI dataset - making the treatment of lakes consistent with OM3 & CM3 i.e. any inland water (other than the Black Sea) as a lake rather than a dynamic ocean. Once that is complete can port to Martin’s ancillary suite - hopefully in the next week or two @LachlanWhyborn
- Discussion around land initial conditions - Martin suggested running N96 using CCI land surface ancillaries to get land initial conditions.
- SSTs/sea-ice
- would be good to test ESA SSTs/sea-ice (0.05 deg) which will be used in highresSST-present @julie.arblaster
- ozone & aerosol climatologies
- create N96 versions to be consistent with N512 @martin.dix
- Code base
- Martin has been testing UM13.5 but will stick to UM13.1 for AM3 release. No change in science so no need for us to upgrade either
- Australian specific PFTs for CABLE are now in ESM1.6. Porting planned to AM3 after initial release
- GC5-central science configuration currently being tested in CM3. Larger impacts than anticipated so currently diagnosing in AM3 AMIP runs. Ideally we will use this version (but not essential) so @martin.dix to keep us posted on timelines
- Urban: waiting on Jan’s work to implement urban stash workflow and then ideally we can use in N512 AM3. @jiachenlu to do some tests at N96 to diagnose the impact of turning urban on
- Table of ancillaries
- Mat suggested creating a table of what is being used for N96 & N512 currently to identify and decide on consistent ancillaries for both @paocorrales @shixue.li
- Optimisation - to be completed once the STASH is finalised
- STASH - @paocorrales will propose a STASH package on Bethan’s Cumulus topic. Will check if the CMIP7 data request includes a HighResMIP2 proposal
Final steps towards running a longer experiment
- agreed to keep meeting fortnightly for now. Next meeting is during the 21st Century Weather workshop so will next meet on 8 December
