About this tool

This calculator implements the R* Composite Priority Index, a rapid assessment methodology for operational triage in climate data preservation. R* is designed for crisis conditions — it assumes institutional instability rather than steady-state operations, and explicitly accounts for the human expertise dimension of data risk. It is not a substitute for strategic value assessment (see Karl utility scoring); it provides the urgency signal that tells you where to look first.
