**February 1st 2024**

**For discussion**

- CABLE-POP at ACCESS resolution - next steps.
- Has CABLE-POPLUC been run globally for future scenarios or higher than present-day CO2 concentration?

**Notes**

- All files needed for CABLE-POPLUC now copied to rp23. Run not yet tested.
- @Jhan tried running code with POP switched on from standard branch but need to use separate CABLE-POP branch. Use CABLE-POP-TRENDY branch.
- No POPLUC dynamics depends on whether c3/c4 - only photosynthesis. So potential to composite grass types when pass to POP. Anything to be considered in LUH2 e.g. harvest fraction.
- POP has been run for future scenarios (without LUC). Disturbance frequency kept constant. Could look at stress mortality outputs and impact on NPP. Australian work is showing mass die-back and recovery in some areas. Could be ‘quirk/bug’. May be fixed in CABLE-POP-TRENDY branch. Alison looking at in Australian case.
- POP hasn’t been run with phosphorus on. Will need to re-visit this. Also performance in ACCESS and whether would benefit from recalibration with newer datasets.
- Offline (CABLE-POP) runs also useful for tuning/calibrating nutrient cycles etc.
- What do we need/want for evaluation on land? Standardised/automated. Think about this for Hackathon. Also making use of ILAMB. Involvement of Land Working Group - and ESM working group.
- Separate executable has implications for offline runs as well.

**Action**

- @clairecarouge to try a test run of CABLE-POP. @juergen available to help with error messages.
- ~8 variables at daily resolution. Have these all been cmorised? @inh599 to confirm what is available and what to run (from ESM1.5 or AM3). Note grid shift between ESM1.5 and AM3 so will need two offline set-ups to match the two grids.  
**Done. Details here: [Run CABLE-POP at ACCESS Resolution - #2 by inh599](https://forum.access-hive.org.au/t/run-cable-pop-at-access-resolution/1697/2)**
- Other input files/ancillaries will need to be reconciled in a staged process including gridinfo. Gridinfo may have been derived from ACCESS. @Jhan to check - also how ancillaries have been updated for AM3.
- @clairecarouge and team to look at formatting of ACCESS meteorology and changes required from cmorised files for CABLE-POP to read.
