Case Study on Combined Lidar-Photometer Retrieval of Volcanic ASH Properties

Abstract

We study the benefit of considering sun-/skyphotometer measurements in a microphysical lidar retrieval. Furthermore, to assess the importance of the aerosol model employed by the retrieval, we compare results obtained using a spheroid aerosol model with results using an advanced aerosol model that considers irregular particle shapes. Preliminary results are shown for the massextinction conversion factor and the single scattering albedo during a measurement case of long-range-transported volcanic ash.
