RTE: Radiative transfer equation method

In LST: Land Surface Temperature Retrieval for Landsat 8

Description

This function calculates Land Surface Temperature using radiative transfer equation method

Usage

RTE(TIR = TIR, tau = tau, E = E, dlrad = dlrad, ulrad = ulrad, band = band)

Arguments

TIR	Raster* object, Landsat band 10 or 11
tau	Atmospheric transmittance
E	Raster* object, Land Surface Emissivity calculated according to Van de Griend and Owe 1993 or Valor and Caselles 1996 or Sobrino et al. 2008
dlrad	Downwelling radiance calculated from https://atmcorr.gsfc.nasa.gov/
ulrad	upwelling radiance calculated from https://atmcorr.gsfc.nasa.gov/
band	A string specifying which Landsat 8 thermal band to use. It can be "band 10" or "band 11"

Value

RasterLayer

Examples

TIR <- raster::raster(ncol=100, nrow=100)
set.seed(2)
raster::values(TIR) = runif(10000, min=27791, max=30878)
BT <- raster::raster(ncol=100, nrow=100)
set.seed(2)
raster::values(BT) = runif(10000, min=298, max=305)
E <- raster::raster(ncol=100, nrow=100)
set.seed(2)
raster::values(E) = runif(10000, min=0.96, max=0.99)
Ts_RTE <- RTE(TIR = TIR, tau = 0.86, E = E, 
		dlrad = 2.17, ulrad = 1.30, band = "band 11")
