01In brief

The short answer.

Systems Science and Modelling tools are the public technical views the platform releases on methods and modelling: maps and model descriptions, each with its time and space reference, sources, licence and uncertainty. Analysis runs in Nexus Foundry for authorized projects, and data that is not released is not available through these pages.

Scoping to review.

Canvas · scoping to reviewDesign, not a record
Data and technical methods: build, test and release in Nexus FoundryA request opens a workspace; data are ingested and validated; the model is built and tested on held-out data; an independent gate approves release with limits; the workspace is stood down and the record kept. Design of the process, not a record of a run.

03Geography

Connected activity in North America.

For data and technical methods, in GCRI's spatial-intelligence reading, the map opens on true-colour imagery, night lights and land cover with relief in 3D and true colour from NASA GIBS, framed on North America; every other NASA layer, live feed and forecast waits in the layer list.

The interactive map needs JavaScript; the layer list and sources are below.

05Fitness for purpose

What every systems modelling tool should state about itself.

Modelling tools serve analysts coupling models from several fields. A specialist checks model version and code location, the scenario set and the coupling assumptions. Tools rest on uncertainty quantification and systems engineering and support the coupled modelling and reproducible modelling topics. Every coupled run records which platform supplied each component model and its version.

  • Model version and code location.
  • Scenario set.
  • Coupling assumptions.
06Build environment
