SCA: Single channel algorithm

Description

This function calculates Land Surface Temperature using single channel algorithm

Usage

SCA(
  TIR = TIR,
  BT = BT,
  tau = tau,
  E = E,
  dlrad = dlrad,
  ulrad = ulrad,
  band = band
)

Arguments

TIR

Raster* object, Landsat band 10 or 11

BT

Raster* object, brightness temperature

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
