This function implements models to estimate soil heat flux for different surfaces and considering different inputs.
1 | soilHeatFlux(image, Ts, albedo, LAI, Rn, aoi, method = "Tasumi")
|
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 |
method |
method used for the G estimation. Currently implemeted are "Tasumi" for Tasumi,2003 or "Bastiaanssen" for Bastiaanssen, 2000 |
