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

Crop coefficient for the mid-season stage

Description

Typical values for the crop coefficient at the end of the late season growth stage, Kc end, are listed in Table 12 for various agricultural crops.For specific adjustment in climates where RHmin differs from 45 % or where u2 is larger or smaller than 2.0 m/s.

Usage

cal_Kcmid_for_singleKc(RHmine, u2e, Ktable, he)

Arguments

RHmine	mean value for daily minimum relative humidity during the mid-season growth stage , for 20 <= RHmine <= 80
u2e	mean value for daily wind speed at 2 m height over grass during the mid- season growth stage (mls), for 1 <= u2e <= 6
Ktable	value for Kc mid taken from Table 12
he	mean plant height during the mid-season stage [m] for 0.1 m < h < 10 m

Value

A value for Kcmid value
