RTE: Radiative transfer equation method

In LST: Land Surface Temperature Retrieval for Landsat 8

Radiative transfer equation method

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	SpatRaster object, Landsat band 10 or 11
tau	Atmospheric transmittance
E	SpatRaster 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

SpatRaster
