penman_day - Daily ET0 using Penman-Monteith

Description

penman_day - Daily ET0 using Penman-Monteith

Usage

penman_day(vtime, vwind, vtemp, vvpd, vheatflux, altitude = 0)

Arguments

vtime	data frame column or vector containing date data
vwind	data frame column or vector containing daily wind velocity
vtemp	data frame column or vector containing daily temperature
vvpd	data frame column or vector containing daily vapor pressure
vheatflux	data frame column or vector containing daily total heat flux (latent and sensible heat flux)
altitude	study area altitude in meters above sea level

Value

The function returns a data frame with time stamped daily potential evapotranspiration

Examples

 ET0 <- penman_day(vtime = de_tha_d$time, vwind = de_tha_d$wind_speed,
                   vvpd = de_tha_d$vapor_p_def, vtemp = de_tha_d$temperature,
                   vheatflux = (de_tha_d$sensible_heat + de_tha_d$latent_heat))
