Here are the minutes from the Land modelling working group meeting. If we’ve missed anything you feel is important please feel free to add it below or edit this post (it’s a wiki post).

DATE: 14/02/2023
Attendees: 10-15

Introduction on the role of the working group:

  • build a community
  • foster collaboration.
  • advise ACCESS-NRI on ACCESS development

Discussion on how to organise the working group meetings:

Gave a short description of COSIMA meetings. The COSIMA community came together because they had to collaborate on the high-resolution. We need to find our points of collaboration.

Proposed points of collaboration:

  • datasets - reference datasets and model outputs
  • evaluation and benchmarking

The meetings should also allow for discussions of interest to a smaller group only (most likely CABLE-specific discussions).

What people expect from the working group:

For the working group to be effective we need to know what participants expect from the working group. A few participants shared their thoughts, we’ll continue at next meeting:

  • Bring JULES and CABLE closer together.
  • Share datasets with more standardisation and quality control.
  • Create a community that has a voice for funding and advocacy.
  • More discussions on the science: how to best represent key processes in the model
  • Get to work on the same code base

Meeting structure:

We will start with fortnightly meetings. Short presentations of work in progress by volunteers at each meeting.

The low attendance was noted. We need to make a stronger effort to communicate the meetings. In particular, we need to emphasise the need to watch the forum topic for people who want to receive announcements via emails.

Introduction of Sean Bryan
Sean joined the land surface infrastructure team at ACCESS-NRI last December. He is currently working on the evaluation framework for CABLE.

ACCESS-NRI plans and status
Claire C. gave an overview of our current projects for the land at ACCESS-NRI and our current directions. We currently focus on two aspects:

  • Evaluation framework for CABLE
  • Migrating CABLE to GitHub

Evaluation framework for CABLE
We are working on a release of benchcab, a Python software to manage the execution of standard configurations for CABLE.
Sean has finished a refactoring of the code to improve its navigation.
The plan is:

  • focus first on single site runs
  • release a version with 3 modes of operation. It runs 2 branches of CABLE, for a standard set of configurations for various sets of met. sites. The analysis is then handled by modelevaluation.org. The site options are:
    • 1 site
    • 5 sites
    • 42 sites
  • extend to spatial configurations and use iLAMB for the analysis.
  • extend to CASA

Migration to GitHb
Description of the migration plan is posted on this forum.
Current blocker for the migration: gaining access to the TRAC database. Hopefully, resolved soon.
Discussion on whether the move to GitHub should coincide with a complete overhaul of the development practices or the development practices could come later in stages. Some arguments either way. It is likely the migration to GitHub will happen first and the development practices will change later.
