Model descriptions for Systems Science and Modelling are published here once reviewed, with their assumptions, evidence and validation. They describe models; they are not live simulations.
Systems Science and Modelling reviewed models are published descriptions of the models used in the methods and modelling field, with their assumptions, data, validation and limits, built on methods such as systems engineering as well as probability and statistics. They describe models; they are not live simulations, and no output on them is a finding.

For reviewed models and scenarios, in GCRI's spatial-intelligence reading, the map opens on true-colour imagery, rain, flood water and daytime surface heat 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.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Model validation | Comparing model predictions with independent observations to judge fitness for a stated use. |
| Model card | A short document describing a model's intended use, training data, performance and limits. |
| Uncertainty quantification | Characterising and propagating the uncertainties in a model to state confidence in its outputs. |
| Surrogate model | A fast statistical model trained to approximate a slow simulation or experiment. |
The bodies and documents this page is read against. Status and editions change; each link goes to the issuing body.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
