Journal ArticleDOI
Inversion with regularization for the retrieval of tropospheric aerosol parameters from multiwavelength lidar sounding
Igor Veselovskii,Alexei Kolgotin,Vadim Griaznov,Detlef Müller,Ulla Wandinger,David N. Whiteman +5 more
TL;DR: An inversion algorithm for the retrieval of particle size distribution parameters, i.e., mean (effective) radius, number, surface area, and volume concentration, and complex refractive index from multiwavelength lidar data is presented.
Journal ArticleDOI
Inversion of multiwavelength Raman lidar data for retrieval of bimodal aerosol size distribution
Igor Veselovskii,Alexei Kolgotin,Vadim Griaznov,Detlef Müller,Kathleen Franke,David N. Whiteman +5 more
TL;DR: Simulations showed that surface area, volume concentration, and effective radius are derived to an accuracy of approximately 50% for a variety of bimodal particle size distributions, which makes this algorithm applicable to large particles, e.g., investigations concerning the hygroscopic growth of aerosols.
Journal ArticleDOI
Depolarization and lidar ratios at 355, 532, and 1064 nm and microphysical properties of aged tropospheric and stratospheric Canadian wildfire smoke
Moritz Haarig,Albert Ansmann,Holger Baars,Cristofer Jimenez,Igor Veselovskii,Ronny Engelmann,Dietrich Althausen +6 more
TL;DR: In this paper, optical and microphysical properties of western Canadian wildfire smoke observed in a tropospheric layer from 5.5-6.5 km height and in a stratospheric layers from 15-16 km height during a record-breaking smoke event were presented.
Journal ArticleDOI
Application of randomly oriented spheroids for retrieval of dust particle parameters from multiwavelength lidar measurements
Igor Veselovskii,Oleg Dubovik,A. Kolgotin,Tatyana Lapyonok,P. Di Girolamo,Donato Summa,David N. Whiteman,Michael I. Mishchenko,Didier Tanré +8 more
TL;DR: In this paper, a model of randomly oriented spheroids for the inversion of multiwavelength lidar data is presented, which is applicable to the modeling of light scattering by spherically symmetric particles only and does not adequately reproduce the scattering by generally nonspherical desert dust particles.
Journal ArticleDOI
Extreme levels of Canadian wildfire smoke in the stratosphere over central Europe on 21-22 August 2017
Albert Ansmann,Holger Baars,Alexandra Chudnovsky,Ina Mattis,Igor Veselovskii,Moritz Haarig,Patric Seifert,Ronny Engelmann,Ulla Wandinger +8 more
TL;DR: In this article, the European Aerosol Research Lidar Network (EARLINET) lidars in the stratosphere over central Europe on 21 and 22 August 2017 were used to identify smoke layers with a 1-2'km vertical extent 2-5'km above the local tropopause.
