Analysis behaviors

Analysis behaviors are those whose only purpose is to prepare data for output. They do not change model state, such as growing trees or updating grid values. They assemble, calculate, or analyze data for the user.

BehaviorDescription
Carbon ValueCalculates the amount of carbon per species and its value.
Dimension AnalysisCalculates the biomass of trees based on DBH. This approach comes from Jenkins et al, 2004.
Foliar ChemistryCalculates chemistry components as a function of DBH.
Merchantable Timber ValueCalculates the value of merchantable timber.
Partitioned DBH BiomassCalculates biomass as a linear function of DBH, partitioned into leaf, branch, and bole biomass.
Partitioned Height BiomassCalculates biomass as a linear function of tree height, partitioned into leaf and bole biomass.
Ripley's K CalculatorCalculates the Ripley's K function for all trees in the plot as well as for the members of each species.
Relative Neighborhood Density CalculatorCalculates the relative neighborhood density index (Ω ) as described in Condit et al 2000.
State ReporterReports the values of state variables.
Storm Killed Partitioned DBH BiomassCalculates biomass of trees killed in storms as a linear function of DBH, partitioned into leaf, branch, and bole biomass.
Storm Killed Partitioned Height BiomassCalculates biomass of trees killed in storms as a linear function of tree height, partitioned into leaf and bole biomass.
Tree Bole Volume calculatorCalculates merchantable tree volume.
Tree AgeCalculates tree age.
Tree Volume CalculatorCalculates the volume of tree trunks to find both merchantable volume and total volume.
