Iteration method for the inversion of simulated multiwavelength lidar signals to determine aerosol size distribution

A new method is proposed to derive the size distribution of aerosol from the simulated multiwavelength lidar extinction coefficients. The basis for this iteration is to consider the extinction efficiency factor of particles as a set of weighting function covering the entire radius region of a distribution. The weighting functions are calculated exactly from Mie theory. This method extends the inversion region by subtracting some extinction coefficient. The radius range of simulated size distribution is 0.1–10.0μm, the inversion radius range is 0.1–2.0μm, but the inverted size distributions are in good agreement with the simulated one.
