SWA: Split-window algorithm

In LST: Land Surface Temperature Retrieval for Landsat 8

Split-window algorithm

Description

This function calculates Land Surface Temperature using split-window algorithm

Usage

SWA(
  TIR_10 = TIR_10,
  TIR_11 = TIR_11,
  tau_10 = tau_10,
  tau_11 = tau_11,
  E_10 = E_10,
  E_11 = E_11
)

Arguments

TIR_10	SpatRaster object, Landsat band 10
TIR_11	SpatRaster object, Landsat band 11
tau_10	Atmospheric transmittance for Landsat band 10
tau_11	Atmospheric transmittance for Landsat band 11
E_10	SpatRaster object, Land Surface Emissivity for Landsat band 10 calculated according to Skokovic et al. 2014 or Yu et al. 2014
E_11	SpatRaster object, Land Surface Emissivity for Landsat band 11 calculated according to Skokovic et al. 2014 or Yu et al. 2014

Value

SpatRaster
