ET24h: Calculates daily ET from a surface energy balance and Weather Station

Description

Calculates daily ET from a surface energy balance and Weather Station

Usage

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)
