Land working group, meeting minutes 2024

Date: 19/11/24
Attendees: 10

Reporting publications using ACCESS models
Use the form on the ACCESS-NRI website, under “For Users” tab.
Under “For Users”, there is also information on how to acknowledge ACCESS-NRI in publications. Please acknowledge ACCESS-NRI and report publication for CABLE offline use if you received help from the ACCESS-NRI land team (or other team) in your project.

There is also a new logo and a new ACCESS model graphic, please update your communication material. Contact access.nri@anu.edu.au if you need the updated material.

Co-chairs renewal
WG have to put a proposal to the SAC who gives approval.
What is the role of co-chairs: post the role statement on the forum.
People to express interest in the role by emailing the current co-chairs. Co-chairs to give a proposal to the WG before sending to the SAC.

Root distribution
High sensitivity of GPP on the root distribution. Using Jackson et al values give low seasonal variability. ESM1.5 is already producing low variability and we don’t want to reduce it more by changing the root distribution.

AU: Look at the effect of FWSOIL or GW because the soil might experience too much water stress.

IH: Look at adapting the phenology? Prescribed in ESM1.5.
Allocation of NPP into leaf area?

Model Evaluation Feedback
Discussion on Enhancing Model Evaluation Feedback Mechanisms for the ACCESS Community

CSIRO is using p73 at NCI to store and share data. Could use the ACCESS-data category to advertise the datasets to the community.

This would be a great way to archive results found by the community. But it won’t change the development of the model. Need some additional step to connect to the development community. User expectations: need to make clear that it’s not because a problem is found that it will be fixed.

It would be good if specific issues identified are reported in the model repositories in GitHub.

Evaluation that shows good results is as important as evaluation that shows bad results.

Good to document the current strengths and weaknesses of ACCESS. Could be useful for universities to find new research projects.

Workshop outcome follow-up
Mat to give a presentation at the next WG meeting about the work he’s done for using ANTS for CABLE ancillary preparation.
ANTS seem to create some odd ancillaries with very sharp boundaries. There are some science choices in there we will want to review and maybe modify.

Abhaas is working on putting in place a pipeline to prepare met forcings for CABLE. Focussing on ANUCLIMATE to start with.
