Calculates daily ET from a surface energy balance and Weather Station
1 | ET24h(Rn, G, H, Ts, WeatherStation, ETr.daily, C.rad = 1)
|
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) |
