public class GecrosCropLAI
extends net.simplace.sim.model.FWSimComponent

Simulates crop biomass by calculating photosynthesis. Takes LAI as an input. Part of the Gecros model.

Consult reference for description of algorithms.

This module calculates only the crop part. For soil water there is the complementary module GecrosSoilWater. There is also a module Gecros, where crop and soil water part are calculated simultaneously.

Compared with Gecros, GecrosCrop has more variables defined as SimVariables that can be output.

Changes

Leaf are index is not calculated by the model, but takes from the input iLAI.

By default, the component calculates DTR by the corrected formula: $$ DTR = DDTR \cdot SINB(1.+0.4 SINB)/DSINBE $$

In the original code, DTR was calculated by $$ DTR = DDTR (SINB \cdot SC/1367.)/DSINBE $$ By setting cLegacyMode to true, one can switch to this formula.
