Model_single_Kc {simET}

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.
