extends net.simplace.sim.model.FWSimComponent

Lintul5 - Simple generic model for simulation of crop growth - Biomass and NPK part

Introduction

The sim components in the package lintul5 implement the Lintul5 algorithms from (L5). They are designed to reproduce same results (up to rounding errors) as the original FST program.

The original model is subdivided into multiple sim components (which should be used in the following order to be as close as possible to the original algorithm).

1. Irradiation
2. PotentialEvapoTranspiration
3. WaterBalance
4. Phenology
5. RadiationUseEfficiency
6. Lintul5

Daylength calculation is performed by the transformer component AstronomicParametersTransformer

PotentialEvapoTranspiration component calculates the potential evaporation and transpiration

Description

The component calculates evapo-transpiration corresponding to the original model's PENMAN() routine.

It takes inputs from the components Irradiation and Lintul5 (fractional light interception FINT).

It's outputs are used by WaterBalance.

For documentation of the algorithms please consult the orginal documentation (L5)

Changes to original

Calculation of irradiation has been moved from PENMAN() routine to Irradiation sim component. This does not affect the result.
