Help for ALPHAE_RE
Program to calculate alpha emissivity by iteration.
PARAMETERS:
INP
Input radiance at sensor
dataset (Halfword) in
radiance (mW/m*m/um/sr)
OUT
Root name for output. Root
will have ".1", ".2" etc
appended for each iteration.
Output includes emissivity and
an extra band of temperature.
All output data in Halfword.
Emissivity data *1.0e4.
Temperature data degrees*100.
SL
Starting line
NL
Number of lines
AMODEL
Selects the model for which the
atmospheric corrections will
be performed via LOWTRAN/MODTRAN
ATEMP
Selects atmospheric temperature
and pressure profiles, if
different from that defaulted
with AMODEL.
AHUMID
Selects the atmospheric water
vapor model, if different from
that defaulted with AMODEL.
AOZONE
Selects the ozone model, if
different from that defaulted
with AMODEL.
HEIGHT
Aircraft altitude (km above MSL)
DATUM
Surface elevation (km above MSL)
NLAYERS
The number of atmospheric lay-
ers in the radiosonde data
(if used).
ALTITUDE
The altitudes of each of the
atmospheric layers given in
the radiosonde data. (km.)
PRESSURE
The atmospheric pressures of
each of the atmospheric lay-
ers given in the radiosonde
data. (mb.)
TEMP
The temperatures of the at-
mospheric layers given in
the radiosonde data. (deg C)
WATER
The water profile in terms
of the parameter WTYPE, for
each layer in the radiosonde
data.
WTYPE
The units in which H2OS are
given. The three types are
relative humidity (RH), dew-
point (DP), and density (DE)
WATERFAC
Varies the moisture profile
by the factor specified
O3FAC
Varies the ozone profile by
the factor specified
CO2FAC
Varies the carbon dioxide
profile by the factor specified
SO2FAC
Varies the sulfur dioxide
profile by the factor specified
CH4FAC
Varies the methane profile by
the factor specified
O2FAC
Varies the oxygen profile by
the factor specified
E
The emissivity assumed for
each band.
DATE
Date of data acquisition. Used
to override the date in the
VICAR label (yymmdd)
ATMODEL
Atmospheric model to be used
(LOWTRAN or MODTRAN)
WAVE
the central wavelength for the
input channels, in micrometers.
(1 value per channel)
NITER
Number of iterations.
