This module contains more/less core model of iLand.
The class Model is the top level container of iLand. The Model holds a collection of ResourceUnits, links to SpeciesSet and Climate. ResourceUnit are grid cells with (currently) a size of 1 ha (100x100m). Many stand level processes (NPP produciton, WaterCycle) operate on this level. The Model also contain the landscape-wide 2m LIF-grid (http://iland-model.org/competition+for+light).
The basic simulation entity of iLand is the individual Tree. Trees live on a ResourceUnit (i.e. trees are stored in lists owned by ResourceUnits).
| double Production3PG::calculate | ( | ) |
return year GPP/rad: kg Biomass/MJ PAR/m2
calculate the stand-level NPP
Standlevel (i.e ResourceUnit-level) production (NPP) following the 3PG approach from Landsberg and Waring.
