The first file should contain the 5 TIR channels of ASTER image data, calibrated in units of milliWatts per square meter per steradian per micrometer. The second file should be the ASTER TIR radiance to temperature lookup table. The default file contains the standard calibration lookup table.
The output dataset will contain surface kinetic temperature for each of the
5 input channels, assuming the emissivities supplied in the EMIS parameter,
and the sky irradiances supplied in the SKYRAD parameter. Note, however,
that if the emissivity is 1.0, the value of the sky irradiance is
irrelevant.
Output pixels are halfword (16 bit signed integer), in units of degrees
Celsius, scaled by a factor of 100.0
For example,
DN = 2531 denotes a temperature of 25.31 degrees Celsius.
The standard VICAR2 output size field. Default will process the entire data set. Example: SIZE = (1,1,200,638)
Starting line (same as SIZE(1)).
Starting sample (same as SIZE(2)).
Number of lines (same as SIZE(3)).
Number of samples (same as SIZE(4)).
These are the values for the full hemisphere downwelling sky irradiance, for each of the 5 ASTER channels. They must be supplied in units of milliWatts per square meter per micrometer.
These are the spectral emissivity values assumed when computing the amount of reflected downwelling radiance in the input, and when using the Planck function to convert from radiance to temperature. Five values are required, one for each ASTER channel from Channel 10 to 14.
In the default mode, linear interpolation is used between lookup table entries. If the keyword NO is supplied, no interpolation is performed, and the closest table entry is used.
