Abstract: | A wavelength-selecting method to improve the precision of retrieving the aerosol size-distribution is presented. The optimal wavelength set selected by using this method can decrease the degree of ill-condition of the Mie matrix effectively, indicating that the optical depth set of the optimal wavelength set is more unjammable than the optical depth sets of other wavelength sets. By using the computer simulation and the actual measurements of the size-distribution of Al2O3 particles in water, the wavelength-selecting method is proved to be validity to some extent. |
