The first file is the file containing all six bands of a calibrated TIMS image, using the IRAD mode and WATTS units. The second file is the file containing all six bands of emissivity data, scaled such that the 0 to 1 emissivity range is mapped to 0 to 10,000.
Output data set in 16-bit integer format of all six bands of ground radiance TIMS data.
The standard VICAR2 output size field. Default will calibrate 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)).
ORG specifies the organizational format of the output dataset. BIL (the default) and BSQ are supported.
This selects the model atmosphere for which the atmospheric cor-
rections will be computed. The program uses a version of LOWTRAN
(or MODTRAN) as a subroutine, to which AMODEL is passed. The exact
parameters of each model is given in the LOWTRAN handbook. The
options in brief:
TR - TRopical model atmosphere
MS - Midlatitude Summer
MW - Midlatitude Winter
SS - Subarctic Summer
SW - Subarctic Winter
ST - U.S. STandard
RS - User supplied (e.g. Radiosonde) model atmosphere
These same abbreviations are used with the HUMID parameter, with
the same meanings.
Example: LMODEL = SW
The ATEMP parameter is used to modify the AMODEL given, with respect to its temperature and pressure profiles. The choices are the same as those given in the AMODEL description and with the same meanings. The ATEMP parameter will only change AMODEL's temperature and pressure profiles and nothing else. Here are the valid strings: TR - TRopical model atmosphere MS - Midlatitude Summer MW - Midlatitude Winter SS - Subarctic Summer SW - Subarctic Winter ST - U.S. STandard Example: ATEMP = MW
The AHUMID parameter is used to modify the AMODEL given, with respect to its water vapor content. The choices are the same as those given in the AMODEL description and with the same meanings. The AHUMID parameter will only change AMODEL's water vapor profile and nothing else. Here are the valid strings: TR - TRopical model atmosphere MS - Midlatitude Summer MW - Midlatitude Winter SS - Subarctic Summer SW - Subarctic Winter ST - U.S. STandard Example: HUMID = MW
The AOZONE parameter is used to modify the AMODEL given, with respect to its ozone concentrations. The choices are the same as those given in the AMODEL description and with the same meanings. The AOZONE parameter will only change AMODEL's ozone concentration profile and nothing else. Here are the valid strings: TR - TRopical model atmosphere MS - Midlatitude Summer MW - Midlatitude Winter SS - Subarctic Summer SW - Subarctic Winter ST - U.S. STandard Example: HUMID = MW
Variable HEIGHT gives the altitude above mean sea level of the TIMS aircraft as it scanned the particular flight line. The units of HEIGHT are kilometers. A default value of 10 kilometers is used as a nominal approximation of a typical TIMS overflight. Example: HEIGHT = 12.5
The DATUM is the mean elevation in kilometers of the targeted terrain above mean sea level. A default value of 1 meter is used if the user does not specify the DATUM explicitly. Again, this variable is used only in the MODE = GRAD, GTEM or EMIS cases. Example: DATUM = 0.2
If the atmospheric model to be used is user-defined (AMODEL=RS), NLAYERS specifies the number of altitudes for which the atmospheric parameters are expressed. NLAYERS has a minimum of 2 and a maximum of 61. It is not used if one of the standard LOWTRAN/MODTRAN models is selected.
This parameter is used only if the atmospheric model to be used is user-defined (AMODEL=RS). It specifies the altitudes of each of the NLAYERS of atmospheric layers given in the radiosonde data. The proper units are kilometers.
This parameter is used only if the atmospheric model to be used is user-defined (AMODEL=RS). It specifies the pressure (in millibars) of each of the NLAYERS of atmospheric layers given in the radiosonde data.
This parameter is used only if the atmospheric model to be used is user-defined (AMODEL=RS). It specifies the temperature (in degrees Celsius) of each of the NLAYERS of atmospheric layers given in the radiosonde data.
This parameter is used only if the atmospheric model to be used is user-defined (AMODEL=RS). It specifies the moisture content of each of the NLAYERS of atmospheric layers given in the radiosonde data. It may be specified in units of dewpoint temperature, grams per cubic meter, or relative humidity, as indicated by the WTYPE parameter.
This parameter is used only if the atmospheric model to be used is user-defined
(AMODEL=RS). It specifies the units used by the WATER parameter to denote
moisture content. The valid values are:
RH for relative humidity (percent of sauration)
DP for dewpoint temperature (degrees Celsius)
and DE for density (grams per cubic meter)
Used to vary the impact of the ozone model in use. All ozone
concentrations are multiplied by this factor prior to atmospheric
parameter computation.
Used to vary the impact of the oxygen model in use. All oxygen
concentrations are multiplied by this factor prior to atmospheric

Used to vary the impact of the carbon dioxide model in use. All
carbon dioxide concentrations are multiplied by this factor prior to
atmospheric parameter computation.
Used to vary the impact of the sulfur dioxide model in use. All
sulfur dioxide concentrations are multiplied by this factor prior to
atmospheric parameter computation.
Used to vary the impact of the methane model in use. All methane
concentrations are multiplied by this factor prior to atmospheric

Used to vary the impact of the moisture profile in use. All moisture
concentrations are multiplied by this factor prior to atmospheric
parameter computation.
TIMSCAL2RE uses the date of data acquisition to determine the proper calibration coefficients. If defaulted, the date in the VICAR label is used. This parameter is needed only if the VICAR label is incorrect, or if an abnormal calibration set is to be used.
Normally, the report file generated by LOWTRAN (or MODTRAN) is discarded at the conclusion of the LOWTRAN/MODTRAN run. If a dataset name is given as the parameter value to LOWFILE, the report for the nadir looking case of LOWTRAN/MODTRAN is saved in that dataset.
Normally, the tabular file generated by LOWTRAN (or MODTRAN) is discarded at the conclusion of the LOWTRAN/MODTRAN run. If a dataset name is given as the parameter value to LOWTAB, the report for the nadir looking case of LOWTRAN/MODTRAN is saved in that dataset.
This parameter selects the particular atmospheric modelling program to be used in the computation. The choices are LOWTRAN (LOWTRAN7) or MODTRAN (MODTRAN3).
This parameter is used to adjust the wavelength calibration of the TIMS filter functions. This value (in nanometers) is added to the wavelengths in the table of spectral response functions.
