Lintul5 - Simple generic model for simulation of crop growth - Radiation use efficiency 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

RadiationUseEfficiency component calculates the radiation use efficiency

Description

The component calculates radiation use efficiency as well as Co2 and temperature correction factor. Calculations taken from original's CROPP() routine.

It takes inputs from the component Phenology.

It's outputs are used by Lintul5.

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

Changes to original

Customizable calculation of day temp

Calculation of used temperature is made customizable by a variable cDayTempFactor. $$ \begin{eqnarray} DTemp <span class="invalid-tag">Ungültige Eingabe: "&"</span> = <span class="invalid-tag">Ungültige Eingabe: "&"</span> TMAX - cDayTempFactor \cdot (TMAX - TMIN) \\ \label{dtemp} <span class="invalid-tag">Ungültige Eingabe: "&"</span> = <span class="invalid-tag">Ungültige Eingabe: "&"</span> (1-cDayTempFactor) \cdot TMAX + (cDayTempFactor)\cdot TMIN \end{eqnarray} $$

  • The default value for cDayTempFactor is 0.25, so $DTemp$ equals the daytemp.
  • If the factor is 0.5, then $DTemp$ equals the mean temperature.
  • If the factor is 0.0, then $DTemp$ is the maximum temperature, if the factor is 1.0, then it's the minimum temperature.

Scale factors for calibration

As some parameters are given as interpolation tables, there have been added additional scale factors to make these values changeable for calibrations:

  • cScaleFactorRUE scales the RUE table RUETB
