Calculates ET-24hs from energy balance and Weather Station
Usage
1
ET24h(Rn, G, H, Ts, WeatherStation, ETr.daily, C.rad = 1)
Arguments
Rn
Net radiation. See netRadiation()
G
Soil Heat Flux. See soilHeatFlux()
H
Sensible Heat Flux. See calcH()
Ts
Land surface temperature. See surfaceTemperature()
WeatherStation
WeatherStation data at the flyby from the satellite.
Can be a waterWeatherStation object calculate using read.WSdata and MTL file
ETr.daily
hourly ETr for every hour of the day. See dailyET()
C.rad
correction term used in sloping terrain to correct for
variation in 24 h versus instantaneous energy availability. See Allen (2007)
