CABLE4 planning: meeting notes

May 2nd

Previous actions status

  • Site-based output from ACCESS - some progress in looking at potential locations for output (following 42 site benchcab sites)
  • CASA implementation, AM3 and for ESM1.6-CABLE3

For discussion

  • LUH2 interpretation for CABLE-POP @Juergen @inh599
  • CASA clean-up, rplant bug fix etc.
  • ESM1.6 for Fast Track

Notes

  • refactorisation work for CABLE-POP. Claire meeting with M. Cuntz to check impact on users.
  • see slides - rangeland quirk. Discussion of what this means and how much should be done as pre-processing. Minimum requirement is consistency and therefore need to include all transitions i.e. don’t neglect primn2past, primn2range,secdn2past,secd2range. Bug found in BIOS implementation. Impact on RECCAP2 budget but very minor.
  • Crops - see slides. No new crops from 1700 but can remove as calculated as a residual. ptoc read in but not used. Commented out about 4 years ago when fixing a difference between serial and parallel versions. Also need to consider BIOME1 factors.
  • crop harvest (and pasture harvest) need to be looked at. Fraction being removed needs to be looked at. If currently 0.9 then too high. Removal once a year, then decays over next year.
  • Reminder of importance of good comments in the code.
  • watch out for spincasa routines etc kept in sync with any changes
  • c13 code. Support of not? Lots of ifdefs.
  • Also how to manage SLI in context of CABLE4 planning.

Action

  • @inh599 and @Juergen to coordinate code fixes across versions ready for next Trendy. Post slides in LUH2 topic.
  • CASA clean-up. Keep logging issues. @RachelLaw to work with NRI team to test and implement.
