BlueSky is a modeling framework. BlueSky modularly links a variety of independent models of fire information, fuel loading, fire consumption, fire emissions, and smoke dispersion. At each modeling step, BlueSky has several different specific models from which to choose. BlueSky is not a model per se because many different modeling pathways are possible within BlueSky.
