An improved inversion procedure for the retrieval of aerosol size distributions using aureole data is presented. The inversion procedure involved a modified Twomey-Chahine algorithm using differential kernels with subsequent averaging and smoothing of the inverted size distributions. The numerical simulations were performed by calculating the angular scattering coefficients between 1.0 ° and 10° for the wavelength of 0.2537 µm using four different aerosol models, including a realistic noise estimate of 4%. It is demonstrated that the differential kernel method is superior to the conventional direct kernel approach.
