Abstract
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 1.08° 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.
