The CAPARS System

The Computer-Assisted Protective Action Recommendation System (CAPARS) is an integrated model for predicting the path and impacts of an atmospheric release of hazardous materials. It is used by a Regional Atmospheric Response Center (RARC) in Denver, Colorado, funded by the U.S. Dept. of Energy, to tell their staff where the plume will go, when it will arrive, how serious the impacts may be, and what protective actions to take.
