soilHeatFlux: Estimates Soil Heat Flux

Description

This function implements models to estimate soil heat flux for different surfaces and considering different inputs.

Usage

soilHeatFlux(image, Ts, albedo, LAI, Rn, aoi)

Arguments

image
surface reflectance image
Ts
Land surface temperature. See surfaceTemperature()
albedo
broadband surface albedo. See albedo()
LAI
raster layer with leaf area index. See LAI()
Rn
Net radiation. See netRadiation()
aoi
area of interest to crop images, if waterOptions("autoAoi") == TRUE will look for any object called aoi on .GlobalEnv
