- ACCESS resolution gridinfo file. Jhan has checked and has slides. Confirmed at ESM1.5 resolution but doesn’t seem to be exact match - grid-shifted (half-grid difference between CM2/ESM1.5, not clear what extrapolation/interpolation was done). Enough differences to worry about that easier to re-do for transparency etc.
- 27 tile can be used if we want. Not an issue. Begun testing but haven’t completely verified. Memory OK. Inserted extra 10 spare tiles in the middle of our original 17 tiles as need to keep non-vegetated at the end. Technically should be the same. Jhan hoping to prove this later today. Deposition code may break bitwise agreement.
- Ian setting up meeting with Peter Briggs. @Juergen expects to work on the LUH2 processing - important for Trendy as well.
For discussion
- Organisation of the work in git @clairecarouge (if this didn’t happen on March 7th)
- Can @inh599 take us through his worked example for grass redistribution?
Notes
Apology: Tilo
- Possibility of feeding back Australian data into LUH system. Need to do the work first here. Also all the other ‘bits’ of LUH would be a problem.
- Discussion of @inh599 slides around grass redistribution. Thinking about grass/pasture/crop. New pasture pft on ACCESS side. Carry fraction of carbon pool rather than carbon pool in POP?? Conservation of CNP is priority. Possibility of using gross transitions for woody and for grass, compared with using net as current. Is this achievable on timeline? Is YPW’s code useable for doing the gross transitions? Extend POPLUC code but also challenging? Do land use change at start of year as currently in ACCESS.
Action
- @RachelLaw to start topic on LUH processing. @inh599 and others starting to look at LUH processing and bringing in Australian information.
- Copy LUH2 processing scripts to CABLE-tools for evaluation.
