Date Published:  10/2001

Brief Description:  NEXUS is a Microsoft Excel ® spreadsheet that links surface and crown fire prediction models.

Complete Description:  NEXUS is an Excel spreadsheet that links surface and crown fire prediction models. It is used to: estimate surface, transition, and crown fire behavior; generate site specific indices of torching and crown fire potential, build and test custom surface fuel models; evaluate alternative treatments for reducing risk of crown fire; explore the influence of different factors on predicted fire, behavior and crowning potential using existing fire behavior models.
