Atmosphere WG meeting minutes 25/02/2025
18 participants on Zoom
ACCESS-NRI workplan Claire Courage
- Asking for community input for the new FY plan - what could/should ACCESS-NRI work on that would most benefit the community
- Draft will be shared April
- Final draft May-June (expect minimal changes)
- Please add ideas to form by 16 March (submit a new form for each idea): this online form
- Scope of work could be large or small (they have had a submission for idealised modelling)
CSET Introduction Jorge Bornemann
- Community Seamless Evaluation Toolkit
- Support assessment, evaluation, verification, across space and time scales (nowcasting to weather forecasting to climate) including ensembles, physics-based and ML models
- A process-oriented focus for model assessment (compare models against each other and observation)
- Modern software, open access, comprehensive documentation, easy to use and contribute to
- Design concepts discussed including fields and operators to develop recipes and produce a diagnostic
- Designed to make it easy for researchers without strong computing skills to use, as well as for researchers developing and coding new diagnostics to contribute to.
- Uses Iris, GitHub, recipes defined in YAML, plots add metadata to JSON file that is used to display on a webpage, cylc workflow, verification uses MET and METplus, VERPy used to produce plots
- Walked through some example recipes, such as spatial plots at a specific time, ensemble mean spatial plot
- Showed how the output plots are organised on the webpage, and example plots: spatial maps, domain mean timeseries, difference plots, histograms, transects, profiles, convective cell statistics (52 recipes so far added including elevated convection diagnostics, age of air)
- Next steps: climate diagnostics, overlay observations with diagnostics
- CSET documentation
CSET on Gadi Vinod Kumar
- Prerequisites: xp65, a project that hosts a web service, hr22, desirable GitHub account
- Stepped through installation, including how to install cylc workflow
- Old installation by Scott works and can open the suite (needs to be updated to latest CSET version)
- Bureau developing an nci site file, but not required (contact Vinod for nci site file)
- Walked through how to use the cylc suite to set up to read in model experiment data, select which fields to visualise, which diagnostics to run and plot
- Provided commands to run the cylc workflow and showed the website displaying the outputs
Compute/storage resources: Heidi Nettelbeck
- Get your experiment proposals in for Q1/2026. We have 1.5 MSU allocation this quarter. See here for how to apply for Atmosphere WG Resources.
