Reviewed models and scenarios

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

Canvas · scoping to reviewDesign, not a record
Reviewed models and scenarios: risk as hazard, exposure and vulnerabilityRisk arises from the interaction of hazard, exposure and vulnerability (sensitivity and adaptive capacity); responses act on each driver and leave a residual risk that is monitored. Design of the process, not a record of a run.

01In brief

The short answer.

Data and Compute reviewed models are published descriptions of the models used in the data and compute field, with their assumptions, data, validation and limits, built on methods such as high-performance, cloud and edge computing as well as data engineering, interoperability and stewardship. They describe models; they are not live simulations, and no output on them is a finding.

02Geography

Connected activity in the contiguous United States.

For reviewed models and scenarios, in GCRI's spatial-intelligence reading, the map opens on night lights, true-colour imagery and population density with true colour from NASA GIBS, framed on the contiguous United States; 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.
