Level 2 Help for ASTERTEMP

INP

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.


OUT

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.


SIZE

The standard VICAR2 output size field.   Default will process
the entire data set.
	Example: SIZE = (1,1,200,638)


SL

Starting line (same as SIZE(1)).


SS

Starting sample (same as SIZE(2)).


NL

Number of lines (same as SIZE(3)).


NS

Number of samples (same as SIZE(4)).


SKYRAD

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.


EMIS

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.


INTERP

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.
