Paper Abstract

A new method is proposed to solve inverse problems with new types of a prior partial information about physical parameters to retrieve. The partial information are relative to integrals of the functions over an arbitrary range of a variable, and/or first and second derivatives of desired functions. They might be provided either form common features of desired solutions or from independent measurements. This inverse problem was solved in the framework of the iterative inversion method under the assumption of log-normal probability density function of measurements. As a typical example of the approach, we examined particle sizing of stratospheric aerosol from multi-wavelength extinction and angular aureole measurements in the visible.
