Analogous with above similar virial expansion relations, a relation between absorption coefficient, absorption
intensity, and molar density under the effect of pressure and temperature could be achieved.
The software package can calculate the following optical properties of aerosols: extinction coefficient, scattering coefficient, absorption
coefficient, single-scattering albedo (SSA), asymmetry parameter, and aerosol optical depth (AOD).
a] and I are scattering coefficient, absorption
coefficient, and radiation intensity, respectively.
