View ActivityData


A measure of emitting or removal activity, generally expressed as a weight, volume, distance, or duration.


Parameter < ActivityData

ActivityData, like EmissionFactor, is a subclass of Parameter.  While Parameter may be used to represent any variable used by emission estimation algorithm, ActivityData and EmissionFactor may only represent a subset of variables: ActivityData objects represent economic output or fuel usage, and EmissionFactor objects represent the coefficients used to estimate emissions based on available activity data.
