Model descriptions for Space and Earth Observation are published here once reviewed, with their assumptions, evidence and validation. They describe models; they are not live simulations.

Space and Earth Observation reviewed models are published descriptions of the models used in the space and Earth observation field, with their assumptions, data, validation and limits, built on methods such as Earth observation and remote sensing as well as space systems and satellite services. 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, daytime surface heat and land cover with true colour from NASA GIBS, framed on the Arctic; 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.
