For discussion
- GitHub Projects for organising tasks @clairecarouge
- Grass types in POPLUC. C3/C4 set at spin-up? Then crop/pasture/range fraction tracked within the grass tile? How? Fraction just used for harvest?
- @RachelLaw slides of POPLUC variables (forest/grass) change over time with some comparison to ACCESS. Slides are uploaded here: Managing CABLE-POP and ACCESS differences in vegetation distribution - Land Surface / CABLE - ACCESS Hive Community Forum (access-hive.org.au)
Notes
- C3/C4 split at spin-up time is limitation. Do we want to let this change over time as climate changes? Is there a need for mix of c3/c4 grasses in a grid-cell. Is the c4 fraction capability in CABLE still functional? Better to have the functionality to carry different grass/crop types in a grid-cell. Will have deal with how to manage transition and what is happening in the soil under each type within ‘grass’.
Action
- Discussion on design for e.g. multiple types within grass @inh599 @Juergen @bens
- @RachelLaw to plot some ACCESS/POPLUC comparisons at individual locations over full timeseries.
- POPLUC output to be checked against input. Crop appears not to be changing.
