Wavelength-independent refractive index of the aerosol; if wavelength-dependence
is required, use aerosol_refrac_file instead. Together with
aerosol_sizedist_file this forms the input to Mie calculations of the
aerosol optical properties. Please see the description of aerosol_refrac_file
to learn how the optical properties are set up.
It is recommended to avoid this option and rather to calculate the aerosol optical
properties externally e.g. with mie and to pass them to uvspec with
aerosol_files.
