Description

Conversion to At satellite brightness temperature of satellite data.

Usage

1
tempconv(x, Ml, Al, K1, K2)

Arguments

x

Image to be converted, in matrix, data frame, or SpatialGridDataFrame format.

Ml

band specific multiplicative rescaling factor from the metadata (MTL file) (RADIANCE_MULT_BAND_x, where x is the band number).

Al

Mp band specific additive rescaling factor from the metadata (MTL file) (RADIANCE_ADD_BAND_x, where x is the band number).

K1

band specific thermal conversion constant from the metadata (MTL file) (K1_CONSTANT_BAND_x, where x is the band number, 10 or 11).

K2

band specific thermal conversion constant from the metadata (MTL file) (K2_CONSTANT_BAND_x, where x is the band number, 10 or 11).

Value

At satellite brightness temperature in Kelvin (K).
