Method of the retrieval of the aerosol particle size distribution (APSD) in the marine atmosphere boundary layer (MABL) from optical measurement data

摘要

Abstract: The retrieval of the aerosol particle distribution function in the marine atmosphere boundary layer for the radius interval up to 30 $mu@m is considered with the use of simultaneous data on the spectral attenuation and small- angle phase function. An iterative procedure is constructed combining inversion algorithms for the spectral attenuation and phase function, each of them being efficient for a specific particle size interval.Numerical experiments with two aerosol models are performed. It is shown that the inversion methodology under discussion makes it possible to retrieve the particle size distribution function for the radius interval 0.2-30 $mu@m with a mean relative error less than 10 percent. !5
