4. Science Configurations#

This module covers how science configurations are developed, configured and run within the Momentum® Framework.

In this module you will learn about…

  • what a science configuration is and why released, versioned configurations are central to reproducible prediction and projection systems;

  • how atmosphere, land, ocean, and sea-ice component models are combined in global and regional Momentum modelling systems;

  • how global coupled and regional atmosphere-land configurations are developed, evaluated, frozen, and released;

  • how Rose, Cylc, MOSRS, and related workflow tools support configuration management, model runs, and experiment traceability;

  • which evaluation tools and evidence are used to assess science configuration performance across weather and climate applications;

  • how practical experiments are set up, modified, run, and analysed for global and limited-area configurations.

At the end of this module you should be able to…

  • explain the purpose of science configurations and how they support seamless modelling across different systems and timescales;

  • distinguish between global coupled, global atmosphere-land, global ocean-sea-ice, and regional atmosphere-land configurations;

  • describe the main stages of the science configuration development and evaluation cycle;

  • identify the tools and repositories used to find, edit, run, and document configuration workflows;

  • make simple workflow or configuration changes using Rose and Cylc and understand how those changes affect a model experiment;

  • run and navigate example global and regional workflows, inspect their outputs, and use Python and Iris to produce basic analysis plots.
