COBRA is a screening tool that provides preliminary estimates of the impact of air pollution emission changes on ambient particulate matter (PM) air pollution concentrations, translates this into health effect impacts, and then monetizes these impacts. This User's Manual provides an introduction, installation instructions and a quick-start tutorial, as well as discussing how to explore baseline emissions data, create a new emissions scenario, and view results.
