Installation
The repository README gives pip installation instructions and lists scmdata and tqdm as the package’s two dependencies.Read 8 Oct 2026 · github.com
Integration note
The documentation says FaIR implements a mathematically equivalent model under certain assumptions and expresses hope that this project could interface with FaIR; it does not state that an integration is available.Read 8 Oct 2026 · openscm-two-layer-model.readthedocs.io
Interface
The project describes its interface as clean, modularised and extensible for a commonly used simple climate model.Read 8 Oct 2026 · openscm-two-layer-model.readthedocs.io
Lesson library
NoRead 23 Sep 2026 · openscm-two-layer-model.readthedocs.io
Model variants
The API documents a two-layer model and a mathematically equivalent two-timescale impulse-response model when state dependence is absent.Read 8 Oct 2026 · openscm-two-layer-model.readthedocs.io
Offline access
YesRead 23 Sep 2026 · openscm-two-layer-model.readthedocs.io
Research use
The model was used as a point of comparison in Phase 1 of the Reduced Complexity Model Intercomparison Project.Read 8 Oct 2026 · github.com
Scenario inputs
The scenario-running API accepts ScmDataFrame, ScmRun, pyam.IamDataFrame, pandas DataFrame, NumPy array or string inputs.Read 8 Oct 2026 · openscm-two-layer-model.readthedocs.io
Scenario outputs
The scenario-running API returns an ScmRun containing the results, including drivers.Read 8 Oct 2026 · openscm-two-layer-model.readthedocs.io
Timestep constraint
Scenario timesteps must be constant because the implementation uses a constant timestep.Read 8 Oct 2026 · openscm-two-layer-model.readthedocs.io
