R Documentation

Conversion to At Satellite Brightness Temperature

Conversion to At satellite brightness temperature of satellite data.

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

`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).

At satellite brightness temperature in Kelvin (K).
