Model_single_Kc: Simulation for evapotranspiration using single crop...

In simET: Tools for Simulation of Evapotranspiration of Field Crops and Soil Water Balance

Simulation for evapotranspiration using single crop coefficient method

Description

Simulation for evapotranspiration using single crop coefficient method

Usage

Model_single_Kc(data, param)

Arguments

data	A data box. Contains the daily data required by the model. You can refer to the function create_modelData()
param	A list. Contains additional parameters.

Value

A list for the model result including a data frame of daily model result ,a list of plots, A data frame of summary data

Note

The stages of data should include all four stages. If a crop has multiple growth cycles, each cycle should include all four stages.

Examples

  data("FIalfalfa")
  #--Parameter preparation
  param_SingleKc<-list(Kc_mid=1.2,#Kcb for mid-season stage
