Location of solar zenith angle file for wavelength-dependent solar
zenith angle.
sza_file file
This option is useful if you want to simulate an instrument
which scans so slowly that the solar zenith angle may change significantly during
the wavelength scan.
The file must have two or three columns. Column 1 is the wavelength,
in nm, and column 2 the corresponding solar zenith angle. Optionally
the third column may contain the corresponding solar azimuth angle. The solar
azimuth angle is only needed when calculating radiances. The wavelength
grid may be freely set. The solar zenith and azimuth angle will be interpolated to
the wavelength grid used for the radiation calculation.
