Description

Calculates daily ET using Penman Monteith hourly formula for every hour

Usage

dailyET(WeatherStation, DOY, height, lat, long, elev, ET = "ETo",
  long.z = WeatherStation$long)

Arguments

WeatherStation	a data frame with all the needed fields (see example)
DOY	day of year
lat	latitude in decimal degrees of the weather station
long	longitude in decimal degrees of the weather station
elev	elevation in meters of the weather station
ET	"ETo" or "ETr"
long.z	longitude for local time

Value

ET daily in mm.h-1
